Advocacy links
What are general feelings on links to advocacy organizations as references? My view is that links to groups that 'spin' the science to promote a particular viewpoint -- whether the Sierra Club on the one hand or the co2science.org on the other -- belong in a separate article on policy. At the very least, links to such organizations shouldn't be under the general heading 'Scientific', which to me implies some attempt at objectivity. Raymond Arritt 01:33, 2 August 2006 (UTC)

Carbon absorption
Could somebody more familiar with global carbon absorbtion please add that oceans actually absorb over 50% of the worlds carbon, a common misconception is that plants and trees absorb most of the world's carbon. This is important as the more carbon the oceans absorb, the more acidic they become (carbonic acid). Once ocean acidity reaches a certain level it will start to kill the ocean wildlife, starting with plankton, and as plankton is at the bottom of the food chain, this will decimate the entire chain. — Preceding unsigned comment added by 85.210.30.128 (talk • contribs) 13:57, 2 August 2006 (UTC)
- That would belong in a carbon dioxide level article rather than this one.
- I'd like to see a source, as carbonic acid is actually a very mild acid.
- Samsara (talk • contribs) 14:04, 2 August 2006 (UTC)
Ok, mild acid. Is not so much the "mild acid" part but the pH. The point is that no matter the acid, if the pH goes down too much so of the excessive H will begin reacting with vital minerals in sea water. As the presence of such minerals decline, the calcium that makes up the skeletons of some of this animals becomes a very attractive reacting partner for the excessive H ions.
- I got this information from a documentary I watched a couple of months ago, however I have about 20 or so documentaries about global warming and I can't remember which one it is right now and seeing this is just one small point it will take a while to find, will post the source when I find it. Thanks for the link to ocean acidification, do you think a note should be added in the predicted effects of global warming section with a link to the ocean acidification page? Also, addressing the above point about carbonic acid being a mild acid, I remember the documentary saying this wouldn't happen any time soon and after checking the ocean acidifcation page I found this "Between 1751 and 2004 surface ocean pH is estimated to have dropped from approximately 8.25 to 8.14 (Jacobson, 2005)." Weak acid or not it will still cause a pH drop eventually and if trends continue there definetly will come a point where the level of acidity will kill plankton.
- As a rule, popular science documentations can give a good overview, but are not very good sources. They often not reliabiliy and they are rather bad at adequately covering multiple viewpoints. Anyways, we do cover this topic already. I've just added a link to ocean acidification.--Stephan Schulz 20:08, 2 August 2006 (UTC)

Is acidification of the oceans a potential compounding effect? i.e. if plankton start to die due to acidification, will that release methane or cause the oceans to absorb less CO2 thereafter?
Al gore editing?
Anyone think Al Gore had edited some of this page? I am sure he has......he loves the subject.
- Well, it does conform to his POV. Perhaps we need to distinguish between the undisputed facts, and matters of scientific dispute.
- What is the determining factor for deciding whether a given proposition is a "fact", a "theory" or a matter of "scientific consensus"? And should Wikipedia articles consider as 'undisputed fact' ideas which are held to be 'consensus' even if they are disputed? --Uncle Ed 13:13, 4 August 2006 (UTC)
So, since evolution is disputed in the US we should indeed give some room to creationist in wiki? It would lower our standards. — Preceding unsigned comment added by 128.148.248.208 (talk • contribs)

Good idea Ed. Lets insist that "flat earthers" be allowed to dispute that the earth is round, and add POV warnings to all the astronomy articles on that basis... while were about it, lets re-write the NPOV policy to remove the undue weight clause... William M. Connolley 19:28, 4 August 2006 (UTC)
- WMC, perhaps you shouldn't be so cavalier when casting aspersions on Flat Earthers. Someday Global Warmers may be just as ridiculed even though they currently enjoy the same "scientific consensus" Flat Earthers once had. Everyone wants to be part of a disaster; maybe that's why every generation thinks the world will end during its lifetime. -- LoudMouth 19:45, 4 August 2006 (UTC)
- When ever in history did the Flat Earth theory have a "scientific consensus"? bikeable (talk) 19:46, 4 August 2006 (UTC)
- Oh, just for a good long while, until it was debunked. Now people laugh at the silly notion of such a thing. I'll grant you that it wasn't as pervasive as this theory, but yeah, there've been lots of things considered "generally accepted" that didn't turn out to be so.
- I notice the lack of any sources. Are you aware of the fact that more than 2000 years ago Eratosthenes not only knew that the Earth was roughly sperical, but also computed its circumfence within a margin of error of roughly 1 percent? A flat Earth has not been accepted by scientific (or any informed) consensus ever since. --Stephan Schulz 20:26, 4 August 2006 (UTC)
- Exactly. It was accepted, then it was disproven, and now scientists and laypersons laugh at it. What goes around comes around. But GW may have a bit longer life cycle; there's a lot of political hay (and money) to be made. (Not that there aren't a LOT of people also deeply invested in seeing GW disproven - don't start calling me a Big Oil empty suit.) My only reason for remaining skeptical of Global Warming is that I believe in calling Bulls*it when I see it.
- We just don't automatically assume your vision in these matters is 20-20, or even 2-50. Skyemoor 12:17, 20 August 2006 (UTC)
- I don't doubt it's getting incrementally warmer. I just doubt that it won't cool again,
- And the damage wrought in the thousands of years in between? We choose not to ignore unpleasant consequences of inaction.Skyemoor 12:17, 20 August 2006 (UTC)
- and I really doubt that somehow evil Americans are responsible for it (AND can reverse it if we just throw enough money at it).
- If you doubt AGW, then you need to provide evidence to sway the opinions of the scientific community. Until then, your name is telling. Skyemoor 12:17, 20 August 2006 (UTC)

There has never been scientific concensus that the earth was round. Thats like saying that there was scientific concensus that hell and heaven exist... There was general belief in the flatness of the earth but it has nothing to do with science. It was general. Also, be careful when you talk about the "scientific" because science back in the day was hardly distinguishable from philosophy, mathematics, and even "religion" (yep, bad spirits are the cause of disease.) It is only in more recent times when specialization has led clear boundaries across fields. Talk about politics. Any one know what happened to the first guy that proved that the square root of two could not be rational...? — Preceding unsigned comment added by 128.148.248.208 (talk • contribs)
- Ermmm....2000 years ago, there was not scientific community or scientific consensus. The fact that the Earth is roughly spherical has been known since before the scientific method has been developed. So there never was a scientific consensus that the Earth was flat, and hence it never was overturned. --Stephan Schulz 07:28, 6 August 2006 (UTC)
- There are a lot of people heavily invested in making sure global warming is real. (Well, as long as it's caused by Americans.) So, believe what you will. Maybe someday we'll all figure out who was right and who was wrong. But I imagine we'll all be long dead before then. From old age, of course. -- LoudMouth 20:01, 4 August 2006 (UTC)
- Who is "heavily invested in making sure global warming is real"? And who claims it is caused (only) by Americans? Assuming the claim that doing something about CO2 emissions is bad for the economy (I have seen no hard evidence for this, but that is a different question), who has an interest in an economic depression? --Stephan Schulz 16:47, 6 August 2006 (UTC)

- You know this is a funny topic to bring up, because there's an amatuer-looking YouTube video making fun of Al Gore and An Inconvenient Truth, but the Wall Street Journal was able to track the origin of the video back to ExxonMobil.

(As an aside, I also wouldn't be surprised to see Big Oil try to figure out a way to cash in on it, were it to ever be a major issue for the general public. Think Phillip Morris running anti-smoking ads). LoudMouth 18:23, 9 August 2006 (UTC)
Ah, this discussion might just go to show us that perhaps what scientists say is influenced many times not by (just) why they think, but what is safe and/or beneficial to say? And if we want to talk about measurements, when were the pyramids built? Does anyone know that? And how did they build them to such precise dimensions, in a place that doesn't change, on exact compass lines? Some things we'll never know, yes. And indeed! That has nothing to do with Global Warming. Nor with Al Gore.

Stephan - (1)Eratosthenes did not prove that the earth was round, he merely used mathematics to estimate its shape and circumference; in other words, he created a model. Models are not proof. The roundness of the earth wasn't proven (by hard, empirical evidence) until September 6, 1522 when the surviving members of Ferdinand Magellan's expedition finally completed a circumnavigation of the globe. Similarly, GW models must be considered theoretical until future events prove or disprove them. (2) Wide-spread belief that the world was flat persisted well beyond Eratosthenes' time. On his first voyage, Christopher Columbus's crew nearly mutinied over fears that they would sail off the edge of the earth, nearly 1500 years after Eratosthenes. And a question for anyone with an answer - How did Al Gore wind up as the point-man for the crusade against GW? The guy has claimed that he invented the internet and that the movie "Love Story" was about him & Tipper (not to mention the fact that he married Tipper in the first place). Not exactly the paragon of credibility a movement usually looks for in a poster-boy. 130.36.62.140 16:59, 21 August 2006 (UTC)
- Magellan's voyage wasn't "proof", either -- it could be explained by a toroidal Earth, among others. Eratosthenes refined a model that we still use today. I confess that as an epidemiologist I find "proof" rather a slippery concept. As for the Gore/internet story, puh-lease -- that old chestnut is simply BS; see [1]. bikeable (talk) 17:18, 21 August 2006 (UTC)
- In that case, Yuri Gagarin proved that roundness of the earth when he became the first to orbit it. And drawing distinctions between "inventing the internet" and "creating the internet" is just playing games with semantics - either way he tried to claim more credit than he deserved. (For the record, I voted for Gore when he ran against Bush, so don't bother trying to chalk this up to me being some kind of right-wing fanatic.)130.36.62.140 17:34, 21 August 2006 (UTC)
- Nope, Gagarin never proved it either. That was all Russian propaganda! It's a good thing, then, that science does not deal with "proof", only with models, theories, and evidence. Note that I never claimed Erathosthenes proved the Earth was round, but that he knew. Nobody will ever prove "global warming models", either, although we might disprove some of them (and then probably refine them into better models). Nobody has "proved" gravity either, and still I brace myself for a fall when I stumble...
- And Columbus crew was, of course, not afraid about falling off the edge of the Earth, but of sailing onto an ocean of unknown size, following the prevailing winds, without adequate supplies. Contrary to a common misconception, Columbus also was not laughed out of every expert meeting for suggesting the Earth was round, but for suggesting that it's circumfence was only 25000 km and that Japan was about 3500 km off the European coasts. --Stephan Schulz 18:12, 21 August 2006 (UTC)
- I suppose John Glenn, Project Apollo and the Space Shuttle program are all just propaganda too? And the Hubble Space Telescope, International Space Station and the multitude of communications satellites allegedly orbiting the earth and making things like wikipedia possible don't really exist? By that reasoning how do we know that all the "evidence" supporting GW isn't just propaganda? The point here is that dragging out the old, tired flat-earth argument for excluding opposition viewpoints is just plain weaselly. The two subjects have nothing in common, since the roundness of the earth can be immediately proven by taking pictures of it from orbit. The effects of human activity on global climate over the next 10/50/100+ years, on the other hand, can only be proven by waiting 10/50/100+ years to see if actuality follows the models.130.36.62.140 18:45, 21 August 2006 (UTC)

- Stephan didn't say the Earth wasn't round, just that you can't prove it -- as you can't prove any scientific theory. In fact, the programs you cite provide excellent evidence to support the theory that the Earth is (more or less) round. Personally, I believe it. I don't know where this little discussion we are having comes from or where it's going, but I suspect it is from that old misapprehension about the word "theory". Just because global warming is a "theory" does not mean we do not understand it relatively well. If you have specific criticisms related to the article, please make suggestions. bikeable (talk) 19:05, 21 August 2006 (UTC)
pro-skeptics bias
From reading the article, and especially from reading the discussion page, I have to come to the conclusion that this page needs an unbiased expert to review it. The page appears to have a subtle bias towards those who claim global warming is either A. not caused by humans, B. a good thing, or C. yet to be proven. Anyone with a high school level of experience in the Bio lab can show that bruning fuels increases carbon dioxide levels, so why are even the basics such as this still the subject of debate in the discussion page? It's time the free time wiki-warriors got out of this fight and let some pro's revise it. —The preceding unsigned comment was added by 68.49.13.119 (talk • contribs) .
- Wow. I am not sure which article you were reading, but, if anything, this article is, and this is being charitable, WILDLY biased in favor of those on the left who believe that global warming is a fact. The statements, arguments, citations, sources, etc. are all VERY selective and TOTALLY biased in favor of one viewpoint -- the alleged anthropegenic nature of global warming. --The Outhouse Mouse 19:22, 7 August 2006 (UTC)
- Why on earth should the scientific opinion be a matter of "left" or "right"? Policy reactions to it, sure, but why the facts?--Stephan Schulz 20:28, 7 August 2006 (UTC)
- An unbiased expert is hard to find these days, and you certainly won't find one lurking in this discussion. But you sure read this thing different than I do; I see your ABC as the complete opposite as far as the main article goes. 72.129.83.116 07:11, 6 August 2006 (UTC)
- No, it's not. It's just that most of the unbiased experts, looking at the evidence, arrive at roughly the same conclusion. That is not bias, it is science. To the original remark: You should not judge the article by the least informed comments on the talk page. Fortunately, most of the article itself has been written by some of the most informed participants. --Stephan Schulz 07:34, 6 August 2006 (UTC)
- Your definition of "Informed" seems to mean arriving at the same conclusions as those who wield the power in this article. Others, who after reading the same papers come to a different conclusion, are treated like witches in 1690's Salem; their additions reverted and their talk bullied into resignation. 66.81.20.197 10:09, 6 August 2006 (UTC)
- This kind of stuff will do you no good, its just whinging. If you can find a specific example that you want to discuss we might get somewhere. Remember to check that it hasn't been done to death already though William M. Connolley 10:45, 6 August 2006 (UTC)
- I agree it will do no good, which is why I didn't start the topic. I just answered it truthfully (which is why it will do no good.) Specific examples??? Oh my goodness that's a deer-in-the-headlights response to a problem that's been ongoing since this article's inception. It's well written and deserves its accolades based on that fact but as far as its usefulness to educators and their students (at least in K-12) it's a little too one sided to be used in any meaningful way. 66.81.20.167 20:54, 6 August 2006 (UTC)
- I should think that finding an unbiased expert is very near to an impossibility. In the process of becoming an "expert" it is human nature to form certain opinions on a given subject, making it very difficult to remain unbiased. Understand that in the strict sense, an unbiased expert should be possible but I believe it to be very, very unlikely. Patris Magnus 18:13, 12 September 2006 (UTC)
I must ask what course you teach, if any. I would never teach this controversy in a science course. Otherwise, I would have to teach that HIV does not cause AIDS, that the earth is not necessarily round, and the evolution may not explain species variety (rather, some designer...) There are opposing "scientists" to the scientific concensus in each example I just mentioned, but that does not mean that you have to teach their views becuase they are all economically motivated. (its funny that the ID movement originator is also one of the first to claim that HIV does not cause AIDS. I think he wants label the disease as a punishment for "Bad behavior."
- What do you want? A balance between a well-supported sicentific theory acknowledged by all professional scientific organizations that ever spoke out on it, that has unanimous support in the literature and overwhelming support in the scientific community on the one hand, and a public relations stunt pushed by a few weirdos on the other? --Stephan Schulz 21:36, 6 August 2006 (UTC)

- And that single sentence speaks volumes on why there is a problem with this article and why many have thrown up their hands in surrender when trying to add things of value. Remember, this is not a research paper and this is not a science journal or even a scientific encyclopedia; this is a free general encyclopedia for the masses. The heavy-handedness of the few in true power smacks of bias. Even in editing out postings in this talk section I see things written that are truly inappropriate from both sides of the aisle but far and away the ones that get expurgated or reprimanded are the ones written against global warming. When I see the bias and rudness in the handling of this simple talk page how is an educator to believe that the same thing isn't being done in the main body? Believe it or not there is a Global Warming controversy out in the everyday world; away from climate scientist polytechnic. When reading something one is on the tip of understanding in the first place and "knowing" there is a controversy one wants to know why others believe in the exact opposite. True, some of the science may be fringe or bit dicey or for every good point brought up on "no" global warming there are two saying why that won't work, but without the balance this reads as a political mailing, and I get enough of those every November. 66.81.21.62 05:25, 7 August 2006 (UTC)
- This article focuses primarily on the scientific case surrounding global warming, however we do have global warming controversy which is intended to cover the social/political/scientific controversy surrounding the subject. How well this, or any other article, does at covering its subject matter is always going to be in the eye of the beholder. Every reader (and editor) comes to this article with their own preconceptions that necessarily influence how it is percieved and written. The best we can do is try to write fairly and use discussion to rectify disparate points of view. Often we do okay, sometimes we fail, but as this is a wiki there are always opportunities to make it better in the future. Dragons flight 05:47, 7 August 2006 (UTC)
- The members of the Left have taken every opportunity to denigrate, minimize, disparage, impugn, attack, and relegate to the "back seat," the opinions of erudite, notable, and well-qualified academics, members of the scientific community, and other members of the cognoscenti who disagree with the official Socialist line on global warming. I am just surprised that they haven't yet used the article to break into an attack on conservatives.--The Outhouse Mouse 19:27, 7 August 2006 (UTC)
- This is true but the article is entitled "Global Warming" not "The Scientific Case Surrounding Global Warming." Most people will type in just "Global Warming" so like it or not this "IS" the frontpiece of the encyclopedia. I expect more from a desk encyclopedia and I certainly expect better here. Don't get me wrong, I'm glad this article is here and that the group is diligent in erasing graffiti; I'm glad it gets people talking about the subject and in seeing scientists actually taking a working part in building such a site. The students like that. At the same time we show the great disappontments we have with the article and the fact that the power hierarchy here, just as in world politics, corrupts. 66.81.21.36 08:26, 7 August 2006 (UTC)
- "I expect more from a desk encyclopedia"...well, in the great Wikipedia vs. Britannica shootout, global warming was excluded because the EB did not have adequate coverage of the topic. We do mention the (minimal) dissent in the introduction (and I've just put in a link to the global warming controversy article that was missing). If you're students are "disappointed with the article", they are welcome to improve it. They should be aware, of course, that a large amount of work by rather knowledgable people has gone into the article and "things I heard on CBS last night" are unlikely to be accepted as well-sourced and authorative. But since we actually have no corrupt power hierarchy, everybody who contributes in a constructive manner is welcome.--Stephan Schulz 09:17, 7 August 2006 (UTC)
(carriage return) The article accurately reflects the current state of the science. Why mislead K-12 students by giving excessive weight to hypotheses that are not widely accepted by scientists in relevant fields? There's already too much of that going on in the U.S. with respect to evolution and some other topics. Raymond Arritt 02:59, 7 August 2006 (UTC)

I come off at times as argumentive (I am) and annoying (I am) and so on and so forth. This article is very good, very well written, very filled with citations supporting the claims. From my viewpoint (Which is: There's a lot of evidence of something but no proof of anything) is that the article is not biased. Nope.
What it is, however, is that it's very focused on some aspects of the debate and not upon others. In that respect, it becomes biased, in a way, by the focus of others who are writing it. That's to be expected. If the subject was one of "absolute" proof or fact, that's a different thing then an article on what causes time, what's the best economic or political system, how much cheese there is in Norway....
To my way of thinking, the reason there's so much contention on this entire subject is that there is no proof as one would normally expect it; what we'd expect from burning methane into a beaker filled with dynamite, vs how burning methane reacts in the atmosphere to cloud cover when the ocean is warmer during the day and the volcanos are errupting under intense blizzards in Spain while holding a giraffe, blah blah blah) Of couse, we all know no professional scientific organization would never be biased or go along with things other than science, things like politics or funding or a degree program or peer pressure or media coverage.
But as to here, "Water turns into steam at 212 F," turns into a discussion of if it's better to cite it as C rather than F, or adding in things like oh, what atmosphere is it, is it not pure or it is pure, is this calories, are we talking about joules, what's the ambiant temperature, what humdity level is it, what's the gravity.... So, let's turn a discussion on physics into one of chemistry into one of experiments in a lab versus in the real world, mix them all together, toss in 8 other subjects, and then not talk about the same thing. Ya think?
"1 calorie is needed per degree Kelvin of temperature change for 1 gram of liquid water." "Blue is better than indigo. Because 460 is a bigger positive number than 430 is."

This page doesn't have a truly neutral point of view. It should use several different pieces of data from independent sources, not just from the same, bogus "hockey stick". --ChevyFanatic 16:19, 7 August 2006 (UTC)
- You mean it might be nice to have a picture showing different reconstructions, not just the hockey stick... oh... wait... William M. Connolley 16:31, 7 August 2006 (UTC)
- Like THIS ONE? Please... --The Outhouse Mouse 19:36, 7 August 2006 (UTC)
- No, like the one in the article actually based on observations. As for the one you reference... you've been lied to, see MWP and LIA in IPCC reports for the details William M. Connolley 20:45, 8 August 2006 (UTC)
- Wow. So you're saying that the Wall Street Journal and the Intergovernmental Panel on Climate Change are lying to me? --The Outhouse Mouse 15:14, 7 September 2006 (UTC)
- The "hockey stick" is based on observations. I do not know of any datasets that suggest global (surface) cooling, or time series without positive interannual trends over the past 30 years. I would be interested to see such a dataset if it exists. LotR 18:29, 8 August 2006 (UTC)
The only question we need to discuss is:
- Do we want this page to reflect a multiplicity of views? Or,
- Do we want this page to lean toward the view that Mann's hockey stick is right and that the recent global warming is mostly human-caused?
Contributors in good faith can disagree on how to implement NPOV, but I'd like to see some agreement from long-timers on the fact that the article should be neutral on all controversial matters. --Uncle Ed 20:32, 8 August 2006 (UTC)
- What specifically do you propose? --TeaDrinker 20:38, 8 August 2006 (UTC)
- Ed appears to be proposing that we confuse attribution of climate change with the HS [2]. Since this is wrong, his entire premise collapses William M. Connolley 20:45, 8 August 2006 (UTC)
- You are imputing Ed's intentions where none exist. Perhaps if you were to ask him for clarification instead of making conclusions for him then we might have meaningful discourse on the subject. --The Outhouse Mouse 15:39, 7 September 2006 (UTC)
- The hockey stick says nothing about cause and is as consistent with natural causes as with anthropogenic causes. The anthropogenic attribution is largely model based, and they are given credibility far beyond the current state of their science.--63.226.208.50 11:40, 9 August 2006 (UTC)
- It's true that the (mean surface temperature) "hockey stick" alone does not provide indication of cause. However, do keep in mind that there are "other hockey sticks." The observed concurrent positive trends in CO2 (1.5 ppm / year) (and CH4) are, in all likelihood, attributable to anthropogenic causes. In any event, this section asks for independent, "non-hockey-stick" datasets for NPOV, but the point is that practically all datasets (that I'm aware of, anyway) show the "hockey sticks." LotR 14:10, 9 August 2006 (UTC)
- True. But the point oyu are missing is that the palaeo record - last 1000 y - has little to do with attribution of recent change, as the link I provided attempts to tell you. The idea that the HS, or others like it, underpins GW is a myth spread by the septics William M. Connolley 16:30, 9 August 2006 (UTC)
- The hockey stick did contribute to global warming alarm, since the rate of warming appeared to increase, but the rate may be an artifact of the better representation of high frequencies in recent data. 20th century solar activity is unusually high, and the interrupting episode of aerosol cooling contributes to the high frequency appearance of what may well be a longer term response to that solar activity. Models are not yet accurate enough to tease out attribution of the recent warming.--63.226.208.50 09:34, 10 August 2006 (UTC)

- Time-scales are problematic. Comparing the last 2 or 20 or 200 years with the last 200 thousand or 200 million is a very long and wide mine field. Sln3412 04:24, 10 August 2006 (UTC)
- Yes, higher frequencies are damped due to the lower resolution of older paleo data, a period of warming as short as the recent one, may well be missed in the paleo data.--63.226.208.50 09:38, 10 August 2006 (UTC)

- Discussion is where we have the space and liberty to clarify what we mean. That seems more like a pinnicle than an abyss. Do you have any remaining questions?--63.226.208.50 09:14, 11 August 2006 (UTC)
Predictions
cut subsection
Global Warming Effects on the Future
The potential effects of CO2 on climate become more significant as we look into the future. Estimated present day reserves of fossil fuels (mainly coal) should last for another few hundred years and will add far more CO2 to the atmosphere than has accumulated so far. Unless human technology or extreme conservation efforts reduces this, atmospher CO2 levels will increase within two centuries to levels at least two and possibly four or five times higher than those that existed before humans. Levels this high are comparable to those last seen tens of millions of years ago in warmer greenhouse worlds. This warming will cause environmental changes. As regional patterns of temperature and precipitation change, impacts on human populations will vary by season. Atmospher CO2 levels will remain high for 1000 of years or more, until the ocean absorbs the excess CO2.
I cut the preceding subsection, as it lacks sources and reads more like an argument for reducing CO2 emissions. Does it even belong here, or should it go to Kyoto Protocol or Emissions trading?
Anyway, we need more info about the relationship of air temperature and CO2 levels in the historical temperature record. Last month, I saw a graph illustrating the point the CO2 increases are caused by temperature increases. At least temp went up first, then CO2 went up; same for down. --Uncle Ed 17:24, 9 August 2006 (UTC)
- Try What does the lag of CO2 behind temperature in ice cores tell us about global warming? crandles 17:45, 9 August 2006 (UTC)
- Just for once I agree with Ed. Sorry about that :-). The article *should* have something in it about future CO2 levels, but I think it does already, higher up William M. Connolley 17:57, 9 August 2006 (UTC)
- crandles - At the end of the article you cited, it reads "CO2 might be stored in the deep ocean during ice ages, and then get released when the climate warms." However, it has been stated more than once on this page that the oceans are currently absorbing large amounts of CO2. Wouldn't this be indicative of an approaching ice age, rather than GW?130.36.62.140 16:21, 21 August 2006 (UTC)
- The oceans currently absorb CO2 because of a simple chemical imbalance. We add a lot of CO2 to the atmosphere, and part of this is absorbed into the ocean. Note that atmosperic CO2 levels still increase. This has nothing to do with an ice age. --Stephan Schulz 16:31, 21 August 2006 (UTC)

The same contributor restored the above section and followed it with this:
- The future within the next 500 years is that when crude oil runs out. After that there will be alternative fuels such as ethanol, biodiesel, hydrogen, and many more types that come from the earths crust and return to the earth crust for a completely renewable cycle. When this comes then global warming will still be here but will start to decline slowly.
I agree that with the above statements that to the extent this information is correct and useful, it needs to be better referenced and presented. Dragons flight 20:24, 9 August 2006 (UTC)
Someone made a change that just made a particular sentence redundant. The changer changed "predict" to estimate, which I thought was fine, but then said that the models estimates assume that we are not going to curb emissions. The next sentence says that estimates are difficult because we do not know future emissions and climate variability. Thus, I too away the part that says "assumes that we will not curb emissions" since this is stated better in the next sentence... Sorry if I am redundant, I am new at this... Brusegadi 04:40, 10 August 2006 (UTC)
- I made that change because the IPCC scenarios are explciity based on 'what if' storylines that assume that nothing will be done about emissions because of climate change. Obviously, even with that caveat the emissions are difficult to predict so I did not see it as contradictory with the following sentence. I still think it is useful to state this assumption up front though. 209.79.152.198 12:32, 12 August 2006 (UTC)
I see what you mean, but I feel it is somehow redundant. Perhaps with better phrasing the assumption of the panel can be explecitly stated. I'll see if I come up with something. Brusegadi 21:51, 12 August 2006 (UTC)
Common misconceptions
Half the Norwegian Wikipedia article on global warming is a list of misconceptions about global warming, with discussion/refutations. The choice of misconceptions seems biased, but mentioning in the article that there are numerous common misconceptions, and listing and discussing them, seems like a good idea. As it is now, several issues that preoccupy many people are represented only on this discussion page instead of in an article. I suggest someone makes a separate article called "Common misconceptions about global warming" that lists and discusses claims that are unscientific, very improbable or poorly founded in science. It is rather obvious that misconceptions are abundant amongst laymen - and I guess laymen are the main target group for the Global warming article. Notice that pro-science advocates seem to forget that a huge number of people seem to hold an unrealistic and often scientifically unfounded sense of impending apocalypse, mainly due to sensationalist tabloid newspapers. This should be addressed, as should a lot of the refuted claims on this discussion page. On the other hand, a list of misconceptions - this is a too strong concept, perhaps? - may end up too black-and-white, showing a disregard for the subtleties that the article in its present form has. I'd welcome viewpoints on this. Narssarssuaq 12:04, 10 August 2006 (UTC)
- This could be useful but probably best as a separate article. The main entry is already bordering on too long. As a start maybe you could translate the Norwegian version. Raymond Arritt 02:30, 11 August 2006 (UTC)
From what I understand, 'misconceptions' refer to what some British have been calling "climate porn." This 'misconceptions' were not brought about by scientists but by media and politicians. Thus, it might make sense to deal with them in the page where we deal with the media and politics of global warming and not in the page where we deal with the science of global warming. Making a separate page may be good, but I feel that it would also be ok to treat them in a more politically leaning article. I feel that as long as we dont put it here, in the science part, it should be fine. Brusegadi 02:37, 11 August 2006 (UTC)
That sounds interesting, all of it. I don't know myself if any of this is anywhere near apolitical on its basic level. It's very difficult to take any large organization or group or subject and see exactly what is social, what is political, what is economic, what is professional, and what is something else (or a mix). So perhaps trying to make this subject anything else than what it is, is impossible. It looks fairly difficult already just in the current format. Sln3412 03:49, 11 August 2006 (UTC)

"The Wegman Report on Statistical Errors of Global Warming Studies" http://energycommerce.house.gov/108/home/07142006_Wegman_Report.pdf
Should this be under "other" and not under scientific? Its energy commerce and it seems to be purely statistical... Just wondering. Brusegadi 19:49, 11 August 2006 (UTC)
- "purely statistical" - sounds scientific to me. --Spiffy sperry 20:05, 11 August 2006 (UTC)
Ok Brusegadi 20:12, 11 August 2006 (UTC)
- Definitely not 'purely statistical' - "In this case we judge that there was too much reliance on peer review, which was not necessarily independent. Moreover, the work has been sufficiently politicized that this community can hardly reassess their public positions without losing credibility." This is clearly a political document that belongs in 'other'.Skyemoor 12:28, 20 August 2006 (UTC)
- While I agree it's not "purely statistical" (I wasn't condoning the use of that phrase by repeating it), it is primarily a statistical (i.e., scientific) report with some discussion on the political nature of the subject. It most certainly does not belong in 'other'. Even Mann doesn't dispute the report's findings on his statistical methods, but complains that it's not peer-reviewed, as if that somehow discredits it. (FWIW, a month ago I was fine with this reference instead being listed elsewhere. But if it's here it should be correctly categorized.) --Spiffy sperry 21:12, 22 August 2006 (UTC)
- It's clearly and unequivocally a political document. At times, they expound on some abstract nuances of the sciences, but then jump lightyears to conclusions that are not at all supported in the report, such as;
- "MBH98/99 has been politicized by the IPCC and other public forums and has generated an unfortunate level of consensus in the public and political sectors and has been accepted to a large extent as truth. Within the scholarly community and in certain conservative sectors of the popular press, there is at least some level of skepticism."
- "Coupled models that have been claimed to show an atmospheric response to oceanic flux shifts are so simplified and lack adequate resolution that they cannot be skillfully integrated over the time periods required to describe true climatic time scales. Again, these models are only indicators of processes that can be operating but with no evidence that they dominate."
- "Especially when massive amounts of public monies and human lives are at stake, academic work should have a more intense level of scrutiny and review. It is especially the case that authors of policy-related documents like the IPCC report, Climate Change 2001: The Scientific Basis, should not be the same people as those that constructed the academic papers."
- "While the paleoclimate reconstruction has gathered much publicity because it reinforces a policy agenda, it does not provide insight and understanding of the physical mechanisms of climate change… What is needed is deeper understanding of the physical mechanisms of climate change."
- "Generally speaking, the paleoclimatology community has not recognized the validity of the MM05 papers and has tended dismiss their results as being developed by biased amateurs. The paleoclimatology community seems to be tightly coupled as indicated by our social network analysis, has rallied around the MBH98/99 position, and has issued an extensive series of alternative assessments most of which appear to support the conclusions of MBH98/99."
- "This study finds no evidence for any earlier periods in the past two millennia with warmer conditions than the post-1990 period. However, natural multi-centennial climate variability, especially as a response to solar irradiance, may be larger than previously thought."
- "The (McIntyre and McKitrick) calculations indicate that these values for the 15th century section of the temperature reconstruction are not significant, thereby refuting the conclusions made by MBH98." (even though the M&M approach has been debunked thoroughly!)
- And these people are statisticians!? Again, this is clearly a political document with a thin veil of 'science' in the form of statistical mumbling. It is not science, it is a sellout. Skyemoor 00:41, 23 August 2006 (UTC)
- It's clearly and unequivocally a political document. At times, they expound on some abstract nuances of the sciences, but then jump lightyears to conclusions that are not at all supported in the report, such as;
- Yes, Dr. Edward J. Wegman is a statistician. 65.95.41.70 03:19, 25 August 2006 (UTC)
- Then it would have been nice for him to have used statistics to prove his point, rather than making political and conspiracy accusations. The few references to statistics in the above quotes are unsupported and leaps of faith. Skyemoor 14:19, 25 August 2006 (UTC)
Statistics is a mathematics tool used by scientists, politicians and others. In this case it seems quite political - the use of statistics does not qualify it as science. Vsmith 01:50, 26 August 2006 (UTC)
- Statistics is a mathematical science. Claiming otherwise is silly. Kyaa the Catlord 01:55, 26 August 2006 (UTC)
Hello again, sorry for saying "purely statistical." Since stats have so many faces... I feel that the bottom line is that, becuase the source is highly political in nature, it should be placed under other. My experience with stats tell me that if you are not very familiar with the data you are working with, you may just mess something up. Perhaps one of the assumptions that is "obviously" met by the data turns out not to be met. My view may be discredited, since Mann has admitted some of the errors that were criticized. Yet, when reading it, I feel that I am getting only one side of the story. Skyemoor points to many examples of text that would never be in a real science source. So, I, again, suggest to try to keep it out. Brusegadi 02:58, 26 August 2006 (UTC)
- blind from the source of the data is a good thing, it prevents you from making unnecessary assumptions. 65.95.41.70 00:33, 27 August 2006 (UTC)
I disagree here, there are assumptions that are VITAL to selecting one statistical procedure against another. And knowledge of the data is essential to knowing if such assumptions are met. What should be avoided is a political interest in a certain result. What can be damaging to a statistician is having a preconceived agenda. Knowledge of the data is rarely detrimental. And that is why the report is not scientific, it belongs under 'other' only because we do not have a 'political' section for external links. Bottomline is that the report was writeen by a statistician and not by a climate scientist. Brusegadi 02:04, 27 August 2006 (UTC)
- While I disagree with others here on the science vs. politics issue, I see no point in continuing that battle. However, I am interested in seeing a source for "Mann has admitted some of the errors that were criticized", since I've only seen this comment. --Spiffy sperry 03:34, 26 August 2006 (UTC)
globalwarminginthenews.com
How is an external link decided? If there is a site that is updated many times a day with global warming news is that a good external link to have? It provides something extra on top of what Wikipedia offers. Some of today's news, after it has been verified and quantified, will make it here as substantiated information. So a good external link site would offer news that has not yet been covered here? Yes or no? Webchat 00:24, 1 September 2006 (UTC)
- The link in question has Google ads. It's been my WP:SPAM experience that the more someone objects to a link's removal, the more likely it is that the intention of adding the link is to generate traffic and revenue to that site. Wikipedia's external link policy discourages non-notable, ad-heavy sites. Also see Wikipedia's policy on external links and Webchat's contribution history. OhNoitsJamie Talk 00:30, 1 September 2006 (UTC)
- Alright. As I have done here - I will place any sites (mine or others I think should be linked to) up for discussion. My only remaining question is what is wrong with Google ads? Does every site have to be without advertising before it has merit? Webchat 00:51, 1 September 2006 (UTC)
- Ceteris paribus, I tend to prefer sites with no ads, although will link to be-aded sites when there is nothing better. A subject like global warming will likely have hundreds of potentially relevant links, so there is a good reason to be picky about the sites linked to. The look of the site, with the look of the appearently parent site robinnixon.com, leads me to think this is a single person's website project, and is a relatively new one at that. I think I would hold off on linking to it until it is better established as a source. By no means is it a bad site, just a bit too limited and new for linking. --TeaDrinker 01:01, 1 September 2006 (UTC)
- Furthermore, the {{spam1}} states, Please do not add commercial links or links to your own private websites to Wikipedia. Wikipedia is not a vehicle for advertising or a mere collection of external links. You've already admitted that this is your site (and I'm guessing the other sites you linked to are owned or managed by you). If your site becomes notable enough, other (non-affiliated) people will add your site. OhNoitsJamie Talk 01:07, 1 September 2006 (UTC)
- I think you've made your point here. But there *is* a dilemma when you yourself are certain you have a good resource that other people will find useful but you aren't supposed to create a link. Whatever. It will stand the test of time. It would be nice to have it linked to in Wikipedia - maybe one day someone will :) I've decided to take ohnoitsjamie up and revise a few articles that need a little work instead - so I won't be bothering you here for a while :) Webchat 01:13, 1 September 2006 (UTC)
- Here's what I'm going to do instead. I found an article that didn't exist mashup (video) something else I know something about. I'm going to try and make a good article here, but it'll be the first I ever started from scratch. So if any of you would care to offer any advice it will be more than welcome. I'm sure it'll start off messy but will get into shape quite soon. Thanks! Webchat 01:38, 1 September 2006 (UTC)
Publicity section
This material would have a good home in the Global warming controversy article but not here. The main article already is long and is in danger of becoming unwieldy. The main article needs to stick to the science. Raymond Arritt 16:03, 22 August 2006 (UTC)
- Thank you for suggesting a suitable place. Wavelength 17:59, 22 August 2006 (UTC)
Question
Just to be sure, if I want to edit the Spanish version of this article, is it ok for the references to be in English or do they have to be in Spanish? In general, can an article written in X language have references in Y language? I am trying to avoid getting in trouble :) I have seen that being done but I am not sure if it is right. Thanks a lot guys and sorry for the diversion. Brusegadi 23:00, 23 August 2006 (UTC)
- Most original research is published in English nowadays, so I think you will have a hard time to come up with Spanish references for the current state of the art. In this situation, it's certainly ok to use English references. --Stephan Schulz 23:27, 23 August 2006 (UTC)

ridiculous, a published scientific paper is un-scientific, yet a group blog is scientific? 65.95.41.70 00:28, 27 August 2006 (UTC)

- My mistake, I removed it. Throw it back in, but the external links section needs a clean up! HawkerTyphoon 01:00, 27 August 2006 (UTC)
- But the blog is ran by scientists. I mean, at least one of them has been called to testify in congress. On the other hand, if adding a blog to the science part is going to make the article lose credibility then lets just leave it as it is.
- The RealClimate blog is the conduit for the paleoclimate community, and is a colloborative 'engine' for continuing climate research direction and information. To leave it out would be missing a big piece of the puzzle. Skyemoor 11:19, 1 September 2006 (UTC)
- Since it is employed by the scientists in the field collaboratively, and criticisms are an openly welcomed part of the process, this site belongs in the Scientific section. Skyemoor 15:49, 1 September 2006 (UTC)
IMBALANCE
The following was posted in the article:
- The warming is the result of an imbalance between ambient levels of sulfurous or nitrogenous aerosols and carbon dioxide in the atmosphere. [1]
If you look at the reference provided it says that smog clearing has 'accelerated' global warming but it says nothing about it being a cause of global warming. Thus, with the source provided, I dont think it makes sense to place this under alternate theories. Brusegadi 04:21, 28 August 2006 (UTC)
References Broken
I've been starting to cite using < ref > because it says that is in the todo section but the problem is something glitched, when I preview the cites start at 1 but when I actually save it they cites start at double however there are. So if you check the references section it doubles up does anyone have any idea how I can fix this. Reverting doens't seem to help. SirGrant 00:52, 29 August 2006 (UTC)
- Ok I'm not sure if it is a local problem (like with my account) but I see this but the thing is if I log out everything shows up fine. I tried logging in on my roommates PC and I still have the problems so I know it isn't computer specific. I don't know why it would work when I'm not logged in but not when I am. If anyone could let me know how it shows up for them that would be a big help thanks SirGrant 01:11, 29 August 2006 (UTC)
- Side note: Before hitting SAVE PAGE, use SHOW PREVIEW, it will save you much aggravation and many versions.
Please review the discussion on references styles for this article, now preserved in Archive 9 [3]. This has been a problem issue in the past. Vsmith 02:22, 29 August 2006 (UTC)
- Ok so was there a general consensus cause after reading that it seems pretty split if there was and I'm citing it wrong I'll go back and set everything back to the way it was. SirGrant 02:44, 29 August 2006 (UTC)
- Not sure about a consensus (guess I need to reread it), but if no consensus is reached, I think policy is that the current style remains. There was an Arbcom case over this last Nov/Dec - got kinda messy. I know that ref systems have evolved and improved since then. But, discuss before unilaterally changing please. My preference is for a Harvard style alphabetized reference section - which I think is now an option for the note style you are using. Maybe with improvements a concensus can be reached now ??? Vsmith 03:04, 29 August 2006 (UTC)
- Ok makes sense, and if again anyone wants me to undo the edits I was doing I will. Hopefully we can possibly get a third voice in here on what to do. SirGrant 03:11, 29 August 2006 (UTC)
- Oh also I wasn't trying to be unilateral in my editing style it just at the top it says Pending Tasks: * Set up HARVARD inline citation system. * Note first scientists to study Global Warming. so that is what I thought I was doing. SirGrant 03:22, 29 August 2006 (UTC)
References
Ignore the above the problem got fixed I think it was just some sort of browser error. Regardless I was wondering what we should do about the citations, I would be happy to go about changing all the links to this format:
{{cite web}}
: Unknown parameter |coauthors=
ignored (|author=
suggested) (help)However I do abide my wikipedias rules and if the current ruling was to leave it as was I'll go back and undo my edits. Sorry about not going through the archives there is just so much stuff it's like a book to read of just talk pages. So if anyone has any oppinions on what I should do I would appriciate it. I would also like to note that I do think the < ref > system is better than having the links in brackets like [ www.whatever.com ] because I think by doing that firstly it is not asthetically pleasing and doesn't contain information about the source you are citing. However I will say it again I will follow the rules and if people decided that it should stay the way it was I'll revert it. Thanks SirGrant 19:38, 29 August 2006 (UTC)
- I was only acting to caution you, before you did a lot of work - as some would disagree. User:William M. Connolley, one of the major contributors to the page is currently on vacation. I am aware of his feelings regarding references and inline links as they are quite similar to mine. I like inline links that take you directly to the referenced page (I typically open the link in a background tab for reference as I continue reading). The note system that you started to implement is quite cumbersome as it requires a complicated three clicks to do what I want. It also produces an essentilly useless numbered list at the bottom of the article. I prefer a reference section arranged alphbetically with Harvard style ref links in the text. Standard for science works. I would like a system using a Harvard style link which links to the ref section for text works and gives a dual choice for online links: a direct link to the website with a secondary link to the reference in an alphbetized reference section. I haven't kept up with the newer Harvard styl ref linking system - need to investigate it more, but am quite opposed to the simple note system you started working on. Cheers, Vsmith 23:00, 29 August 2006 (UTC)
- Yeah I read about William M. Connolley and about the arbitration that is why I haven't been citing any more sources till I can maybe get some instruction on what to do because honestly the only person who has even responded to me is you Vsmith and you kinda seem unsure and I don't want to continue until I get some sort of official word Thanks. SirGrant 23:10, 29 August 2006 (UTC)
- Well, here is my opinion: I don't mind too much either way. A good reference system is certainly worth having, and your work seems to be on the way towards it. On the other hand, the status quo works ok, too. Given that William seems to have the strongest opinion, we should probably wait till he's back. --Stephan Schulz 23:18, 29 August 2006 (UTC)
- I agree with Stephan that sounds reasonable. I'm gonna leave a message on William's talk page hopefully he will respond fairly soon. If not I'll go back and revert my edits but hopefully he can give us some sort of judgement in a reasonable amount of time SirGrant 23:43, 29 August 2006 (UTC)
I'm back :-) I'm still of the opinion that two-clicks-to-link is really really annoying... I'm with Vsmith on this William M. Connolley 19:44, 1 September 2006 (UTC)
- ok, I'll change it back tonight SirGrant 20:08, 1 September 2006 (UTC)
On Wegman and Ritson
I was doing my weekly reading of realclimate, and I saw the Ritson links. Mainly:
http://www.meteo.psu.edu/~mann/house06/RitsonWegmanRequests.pdf
http://www.meteo.psu.edu/~mann/house06/RitsonLetterWaxman.pdf
I feel that if we include the Wegman we should at least be entitled to: 1) Place the links above in the 'Other' external links part of the article, since they bring into question the credibility of the W report in a scientific manner. 2) We could simply remove the W report altogether for the reasons in 1. 3) we could make an article about the wegeman report as someone suggested above. The article would mention the controversy surrounding the report.
If my view is accepted, then I vote for either of the first two options. Also, if most prefer option three, we would have to mention the report in the main article (in order to provide a link) and remove it form the 'other' external links. Thanks and have a lovely day, Brusegadi 03:55, 1 September 2006 (UTC)
- I vote we give it it's own article, so that it can be exposed for what it is. Skyemoor 11:21, 1 September 2006 (UTC)
There is now an article on Wegman, the guy, and most of the stuff about the report is there. Perhaps we should place this there??Brusegadi 22:03, 9 September 2006 (UTC)
the whole story
I know the point of an article on "global warming" is largely to talk about the recent climate warming and how it might have large affects on human civilization, but isnt the article becoming political and non-sientific by totally omitting just what this warming means in terms of the history of the planet over geological time? Temperature and CO variation over millions of years is an order of magnitute greater then what is measureable since the industrial revolution.
Also the biomass section is not up to date it was just in the mainsteam news recently that there were studies showing biomass increasing with increased CO2 INDEPENDENT of other factors like soil and water. http://www.co2science.org/scripts/CO2ScienceB2C/articles/V9/N33/B3.jsp

- This link seems to be about reproductive responses not about biomass balance. Hmmm. an order of magnatude over a period 5000 times longer; do you reckon the current change is at a normal rate of change? crandles 23:40, 2 September 2006 (UTC)
- A few clarifications: (1) co2science.org is an advocacy site, not "mainstream news"; (2) the cited article does not say what you claim it does; (3) the cited article does not say what co2science.org claims it does. The article concludes that "development rate is inversely correlated with life span across tree species (Govindaraju, 1984; Enquist et al., 1999; Loehle, 2000, 1988; in conifers). If the responses obtained in this study result in allocation tradeoffs, and these trees reproduce early and die young, then CO2 enrichment may increase population turnover rates rather than stand biomass." In other words individual trees will grow and die faster, but the net biomass accumulation will not necesasrily change. Raymond Arritt 00:20, 3 September 2006 (UTC)
Disproven
I seem to remember hearing a while back that the theory of global warming was disproven. Several times I think. PowderedToastMan 08:04, 5 September 2006 (UTC)
- Nope, in fact it is generally considered to be accurate, according to the best science we have. --TeaDrinker 08:13, 5 September 2006 (UTC)
- And therefore you call it "consensus"? Three men make a tiger. --NimNick 08:36, 5 September 2006 (UTC)
- The world's scientific academies calls it consensus. Other references with more endorsements as well, including the American Meterological Society, and so forth. Skyemoor 10:44, 5 September 2006 (UTC)
- What is the connotation of "consensus" which you are using? You are not aware of it. Quote of Scientific consensus: "Scientific consensus is not, by itself, a scientific argument, and is not part of the scientific method". Of course, the using of this term is very new and political correct; and it is similar to [Argumentum ad populum]: "(Latin: "appeal to the people"), in logic, is a fallacious argument that concludes a proposition to be true because many or all people believe it;". Maybe there is a relevant men made effect in global warming. Maybe not. But science can't know it. How can there be a consensus on things you don't know? That makes a religious believe and politics will establish an Eco-dictaturship to overcome state failures, war costs and state debt. --NimNick 11:29, 5 September 2006 (UTC)
- The world's scientific academies calls it consensus. Other references with more endorsements as well, including the American Meterological Society, and so forth. Skyemoor 10:44, 5 September 2006 (UTC)
- "Scientific consensus is the collective judgment, position, and opinion of scientists in a particular field of science at a particular time. Scientific consensus is not, by itself, a scientific argument, and is not part of the scientific method; however, the content of the consensus may itself be based on both scientific arguments and the scientific method." The full quote answers your question, doesn't it? If not, visit the links above. If you want to change the minds of the world's scientific bodies, go right ahead. And come back here once you do, so we can update WP. Skyemoor 11:38, 5 September 2006 (UTC)
- No, it answers no question. The "consensus" may itself be based on both scientific arguments but this doesn't mean that it is. And then, you tell me that I shall fight against a reglious believe. You act the fool. The world's scientific bodies must not be changed. They must only be fairly adopted but there are powerful interests to control peoples behavior and their economical ressources. --NimNick 12:18, 5 September 2006 (UTC)
- Actually, Mr. Skyemoor, you'd be surprised to find out, how many sicentists share NimNick's sane point of view but keep silent, because they are afraid to lose their jobs. "Global warming" alarmism is a religion, not science, and this Wikipedia article is outrageously biased against facts, one of the worst I've ever seen. Alas, prejudice always prevails in scientific circles -- until the next superstitious fad replaces it. Arvin Sloane 07:15, 6 September 2006 (UTC)
- Well yes, we would be surprised - if they've kept silent, how do you know? Intuition? William M. Connolley 08:10, 6 September 2006 (UTC)
- Mr. Connolley, what if I am one of them, and know many more? Do you seriously believe that I would continue to hold my tenure if I would have made a statement against the global warming hysteria, and sign such a statement with my real name? What is happening now over the alleged climate change is feeding frenzy, not science, and this Wikipedia article is a clear reflection of this craze, a typical argument from dishonest intelligent design. A stampede of cattle can be defined as a consensus of cows but the existence of such consensus proves neither that cows are running in the right direction nor that they have any reason to run in the first place. Arvin Sloane 08:27, 6 September 2006 (UTC)
- I don't know Mr Connolley, but hopefully he won't mind if I answer for him :-). The asnwer is, of course you would keep your tenure (if you were one of them, which you aren't), just like Lindzen or Spencer. Now... we can try to sort out some of your confusions. A consensus proves nothing of itself other than that a lot of people agree. Which is why the article doesn't say: "There is a consensus, therefore...". Instead, it describes the state of the science and says there is a consensus over it. Notice that you, like many septics, can't quite decide if there is a consensus over GW (but that it proves nothing); or that there isn't even a consensus (in which case your previous para makes no sense) William M. Connolley 09:24, 6 September 2006 (UTC)
- So you want to say that "scientific consensus" is a weasel term, and the doctrine of "scientific consensus" is not vulnerable since nobody can know the real meaning of "scientific consensus". --NimNick 09:46, 6 September 2006 (UTC)
- Nope, scientific consensus makes perfect sense. You just need to remember to get things the right way round: there-is-a-consensus, *therefore* the science says... is wrong. The-science-says-and-people-agree, *therefore* there is a consensus is right. Fairly simple, but many people seem to find it hard to understand William M. Connolley 19:20, 6 September 2006 (UTC)
- Ah, and therfore scientists like Lindzen are writing, there is no consensus, and therefore you must misuse a real name for your user-acount. Troll. --NimNick 20:10, 6 September 2006 (UTC)
NimNick writes: "You act the fool", "Global warming alarmism is a religion, not science", "Troll" &tc. By your condescending tone, you have lost any modicum of respect here and will be ignored. Skyemoor 21:10, 6 September 2006 (UTC)
- This is the same state as it already has had. So what do I have lost? --NimNick 21:49, 6 September 2006 (UTC)
- William M. Connolley (whoever you are), I admire your chutzpah. What makes you think that "I am not one of them"? Intuition, perhaps? There has been an article in WSJ recently by Sharon Begley (Has String Theory Tied Up Better Ideas In Field of Physics? June 23, 2006; Page B1) that explains how scientists sceptical about prevailing fads are left out of their jobs. Lindzen and some others made their names long before the global warming scare followed the equally meaningless global freezing scare. For young scientists, however, sceptical attitude toward this subject is strictly taboo. As for non-existing "consensus," any article on "global warming" that doesn't mention works by Ross McKitrick, Robert Balling Jr., Randall Cerveny, Oliver Frauenfeld, or Robert E. Davis, to name a few, is no more than ideological propaganda (aka "brainwash"). Arvin Sloane 18:36, 6 September 2006 (UTC)
- I am who I say I am. Unlike you, who are a nameless anon. You're not one of us (not them) because your ignorance is too obvious. Just to prove it, you make the obligatory septic reference to global cooling. Incidentally, you have the wrong Mc: McI has the better reputation. I'm not aware of Randall Cerveny, Oliver Frauenfeld, or Robert E. Davis as skeptics, but who knows? One might equally well assert that an article that doesn't mention Mann is odd... before remembering that this is the overview page and looks at temperature record of the past 1000 years William M. Connolley 19:20, 6 September 2006 (UTC)
- Mr. Connolley, if you are who you say you are, why did you say (see above) that you "don't know Mr. Connolley"? Or is it that your academic eminence should be obsequiously addressed as "Dr." only? Or is it that you are just wasting my time? Reasons for my unwillingness to disclose my real name here have been explained to you in painful clarity. Articles by Randall Cerveny, Oliver Frauenfeld, and Robert E. Davis constitute part of Shattered Consensus, a widely known collection of essays disproving the "consensus" argument as abused in "climate change" mock-science. Your not being aware of it doesn't bode well for your reputation (if any). Mann has been proven to have tampered with the evidence and to have geared his methods to the intended effect, he is definitely not the one to be mentioned here. IMO, all references to "consensus" should be removed from this article immediately, and its grade to be lowered from "FA" to "B." Arvin Sloane 20:21, 6 September 2006 (UTC)
- The same Randall Cerveny from Arizona State University, where Robert Ball runs the Office of Climate, a well known climate change skeptic who has accepted funding from Exxon? That's who you hang your hat on? Sorry, out of 120 climate researchers working on the IPCC report, only two disagreed with the summary statements. Provide the 'proof' of Mann's tampering, and I don't mean the disreputed M&M damage control rewrites. We'll let the climate scientists determine the consensus, not Faux News adherents. Skyemoor 21:10, 6 September 2006 (UTC)
see here. Count Iblis 13:23, 5 September 2006 (UTC)
Since we seem to be enjoying the absurd task of exchanging credentials in wikipedia, allow me to say that I am Emeritus Professor at -University of your choice.- I will not say my name, since they may stop funding my research. Besides, I promised my wife I was going to stop having pointless arguments in Wikipedia... On a more serious note, the funding argument is bogus. I wonder how much Exxon would be willing to pay a scientist, if the latter found strong, REAL, evidence against global warming. So far, the only thing EXXON has been able to fund are mere distractions, aimed at the general public, that would be read with abundant humor by the academic circles if it were not for the fact that what we have at stake is the well being of our planet! Yet, since I enjoy morbid humor, they make me laugh all the same. Brusegadi 21:25, 6 September 2006 (UTC)
- As soon as "Exxon funding" is mentioned in a climate change discussion, everyone following it knows that there is no point to continue: we are dealing with the environmentalist religion here, not environmental science. Very sad that such zealots seem to have taken over "climate change" section and many other sections of Wikipedia. In itself, Wikipedia has been a great idea. However, like most great ideas, it is being actively perverted by fanatics and ax-grinders of all sorts. Nothing is new under the Moon, as Copernicus would say. Arvin Sloane 21:57, 6 September 2006 (UTC)
- Yes, I have noticed that the 'Exxon funding' tends to end many of these pointless discussions. Curious fact! It took me a long time to join the 'religion' of global warming. I really did not want to believe in it, because like most religions, joining it would mean that I would have to make great sacrifices. Catholicism could not convert me, the church of the WMDs could not convert me, but Global Warming! They were the first religion ever to offer belief based on fact, throwing the concept of faith and the 1% doctrine out the window! Horray for the MODERN RELIGIONS!Brusegadi 22:10, 6 September 2006 (UTC)
Before we get distracted onto the tedious funding arguements, perhaps we could return to a subtle point which I fear you all missed... what do you notice about Randall Cerveny, Oliver Frauenfeld, or Robert E. Davis? Yes, thats right, they are all red links. It doesn't bode well for their importance. So instead of tedious talk, how about someone who considers them of any importance (hello, septics!) writing a decent article about them, *including* what they think about GW, nicely sourced to published papers. Now *that* would be useful. BTW, thanks for mentioning SC - nice to know where you're getting all your ideas from William M. Connolley 22:43, 6 September 2006 (UTC)

New Ice Core Data
There is new ice core data from the British Antarctic Survey, showing carbon dioxide levels as higher than at any point in 800,000 years. Does this constitute reliable enough information to replace the existing figures in this article? I'll leave that up to the experts on this page, but it seems to deserve consideration. 130.195.86.38 12:01, 5 September 2006 (UTC)
- It turns out that... the 650 kyr CO2 is published. The 800 kyr was presented at EGU (last April) but is not yet published. If it exists on the web in "pre-pub" form I don't know where William M. Connolley 19:39, 7 September 2006 (UTC)
- The release from the BAS is here [4] and its been widely republished in the popular media in the last few days, eg [5], which is why I stumbled accross it. Best wait for publication then... 125.237.74.41 23:38, 7 September 2006 (UTC)
OK, having given the details of the original post here a thorough beating, can we now aknowledge its point? If there are in fact reliable ice core samples for the past 650,000 years, and CO2 levels are higher today than at any point since then, we have to ask at least two questions: 1. Have C02 levels been steadily increasing (on average) over the past 650,000 years? or 2. Is there a significant deviation in the trend at some point near the start of the industrial revolution? A third question, possibly, cuold be: Is there a correlation between human population increase and CO2 increase? These are relatively simple questions, and I would be surprised if the global scientific community had not already begun to investigate them, yet data of this nature seems to be very pervasive (or nobody agress). Or am I just not reading enough, or carefully enough? The proof is in the pudding. -Nick
- As you say, you are not reading enough, or carefully enough. Your first two questions are directly answered in the Global warming article itself. Your third question is a bit vague, but there is indeed a correlation between human population increase and CO2 increase in that both have been increasing at an increasing rate since about 1750.

See here. Count Iblis 19:01, 7 September 2006 (UTC)
- I short-ciruited the process ;-) William M. Connolley 19:40, 7 September 2006 (UTC)
- Do you really think that smug, trollish remarks have any place here, Mr. Connolley? The only thing you have short-circuited is your brain, and that was, probably, long ago. As soon as I will have some time, I will undertake a major re-writing of this article to make it much shorter, balanced, substatiated with hard experimental data, and removing any and all irresponsible conjectures, including any references to the non-existent "consensus." Arvin Sloane 20:27, 7 September 2006 (UTC)
- Arvin, this is the real universe, not the Rightwingoverse :) Count Iblis 01:34, 8 September 2006 (UTC)
- Thanks WMC. About time some common sense was shown towards people vandalising the encyclopedia by inserting rubbish. Tell me to get back to work! 01:28, 8 September 2006 (UTC)
- Iblis, neither it is an Eco-nut-verse. BTW, I haven't made any changes yet in this article. But I will, starting with "consensus" POVs. Arvin Sloane 02:25, 8 September 2006 (UTC)
- If you are doing major rewriting, I would suggest doing so in user space, e.g. under User:Arvin Sloane/Global warming, and getting consensus on that version. This was recently a featured article, and major rewrites will require some consensus among editors. Also, please log in if you are using the name of a registered editor. thanks. bikeable (talk) 02:41, 8 September 2006 (UTC)
- And the best place for Arvin to start seems to be Global Warming Controversy. Skyemoor 02:47, 8 September 2006 (UTC)
- First of all, I would like to remove (if I achieve any modicum of agreement here, of course) the paragraph starting with "However" in Alternative theories section. Naomi Oreskes is a professor of history, not climatology. Her infamous count of articles neither disproves nor challenges any of the alternative theories in question. It has been a political action, not a scientific critique. It is deplorable that Science magazine has become politicized enough to allow such a manifestly unscientific publication. Wikipedia should not repeat this mistake. This paragraph doesn't belong in serious article about global warming. Arvin Sloane 04:23, 8 September 2006 (UTC)
- No. The fact that these views are held by only a small minority of scientists in the field is relevant, according to the standards of Wikipedia. See WP:NPOV, under "Undue weight." However, I'd consider it appropriate to leave out references to the Oreskes piece and simply state that these views have little support among climate researchers. Raymond Arritt 04:38, 8 September 2006 (UTC)
- Einstein developed General Relativity and was ridiculed for his theories. Was he, then, in a so-called "small minority?" What about Galileo when he stated that the Earth revolved around the Sun? Did that also put him in a small minority?
- In this case, alternative theories are views held by a significant minority. In the history of science, significant minorities (Galileo, Copernicus, Mendel, Darwin, Wegener... should I continue?) proved to be right more often than not. Therefore, in a section dedicated to alternative theories, emphasizing the majority POV is giving it undue weight. After all, the rest of the article is relentlessly biased toward anthropogenic interpretation of global warming. It is so full of "may bees" and "ifs," it's really difficult to find any incontestable information in it. So, please, give it a break, and leave this ideological passage out of Alternative theories section altogether. Arvin Sloane 05:15, 8 September 2006 (UTC)
- First, Einstein came up with a hypothesis to describe physical relationships, to put it succinctly, between mass, light, and gravity. He struggled to gain acceptance of this idea, though some skeptics held out for decades. This is exactly what is happening in global warming; the few remaining skeptics will gradually lose all significance.
- In this case, alternative theories are views held by a significant minority. In the history of science, significant minorities (Galileo, Copernicus, Mendel, Darwin, Wegener... should I continue?) proved to be right more often than not.

- Second, Galileo, Copernicus, Darwin, etc were struggling against religious leaders rather than the scientific community. Again, the same can be said for global warming, though climatologists are struggling against fossil fuel corporate propaganda that some have taken on as religious beliefs. Skyemoor 18:08, 8 September 2006 (UTC)
- Demonizing one's opponents is always an excellent method of distracting attention from the paucity of one's own argument. Seems to work in the political arena, so why not here? --The Outhouse Mouse 11:27, 11 September 2006 (UTC)
- No need to 'demonize' certain fossil fuel corporations, the evidence is clear against them. Visit www.exxonsecrets.org Skyemoor 11:31, 11 September 2006 (UTC)
- Hrmm...I notice that site has a lot of "theories" about how Exxon spends its money, but it gives you absolutely no information about who is behind or funds that website itself. --The Outhouse Mouse 11:10, 12 September 2006 (UTC)
- No. First of all, the number is very small at this point not even what could be reasonably called a "significant minority". Second of all in fact very often views which are held by a significant minority turn out to eb wrong. The only reason you think that they "proved to be right more often than not" is because you remember the cases where they did and don't remember the cases where they didn't (in addition to the matter that all views by definition start out at the ultimate minority of 1 person and go up from there). Third, this is not at all like the examples you gave since the number of supporters has gone down not up. Fourth and finally this is all irrelevant. What the general trends in science are do not in any way shape or form alter how to apply WP:NPOV. JoshuaZ 05:23, 8 September 2006 (UTC)
- No. Because "significant minorities" have been correct in some cases does not mean that being in a "significant minority" makes you likely to be correct. Oreskes' contribution to the discussion is an extremely valuable one and deserves to be highlighted here. I even disagree with RA about not referencing her -- if we make a statement like that one without a reference, it'll be removed immediately. It should stay as is. The "alternative" theories must be clearly qualified by the fact that very few people take them seriously. bikeable (talk) 05:29, 8 September 2006 (UTC)
- Well, so far we've got two votes against one in favor of removing the reference to the "valuable contribution" of counting other people's articles in a pre-sorted catalog, and assessing them subjectively from an extremely biased POV. That's a progress. I'll wait a day or two for other opinions. though. Arvin Sloane 05:38, 8 September 2006 (UTC)
- Of course I agree with you. The Oreskes study is at least disputed. Not only by Peiser. This is no extreme minority. --NimNick 10:32, 8 September 2006 (UTC)
- If counting votes is what you are doing, then, I am against removing that reference. Brusegadi 05:43, 8 September 2006 (UTC)
- Here are some arguments against the contentious "consensus," which several of my colleagues, me included, find compelling. Being pressed for time, I am quoting from Steven Milloy:
1. "Global warming" is a fact - it's definitely warmer now than when it was colder (profound, no?) 2. The rate of current warming and the identity of the most significant climate forcings are contentious items in the debate. 3. Land use change and other activities guarantee some human influence on climate - the degree is contentious. 4. Near-surface temperature reading amalgams indicate rapid warming ongoing. 5. Near-surface temperature reading amalgams are composites gathered from less than 1% of the Earth's surface. 6. Near-surface temperature reading amalgams are subject to local influences. 7. Near-surface temperature reading amalgams have suffered significant urbanization with the closure of rural recording stations. 8. Near-surface temperature reading amalgams are adjusted for UHIE corruption - the degree and the methodology are contentious. 9. Near-surface temperature reading amalgams vary widely by region, with better financed and maintained regions showing little warming. 10. Radiosonde balloon measures test the well-mixed atmosphere. 11. Radiosonde balloon measures are significantly less subject to local influences and UHIE than near-surface temperature readings. 12. Radiosonde balloon measures do not indicate atmospheric warming in the 1,000mtr-10,000mtr height where enhanced greenhouse warming should theoretically be readily apparent by now. 13. Satellite-mounted Microwave Sounding Units test the well-mixed atmosphere. 14. Satellite-mounted Microwave Sounding Units provide near-global coverage. 15. Satellite-mounted Microwave Sounding Units are not subject to local influences or UHIE. 16. Satellite-mounted Microwave Sounding Units suggest a small tropospheric warming trend (about three-fourths of one degree (C) per century). 17. General Circulation Climate Models are programmed to show warming proportionate to atmospheric carbon dioxide levels. 18. General Circulation Climate Models do exactly as they are programmed to do. 19. General Circulation Climate Models cannot yet be programmed with the complexity of the atmosphere. 20. General Circulation Climate Models have yet to demonstrate greater predictive power than a table of random numbers.
All a bit dull, and badly formatted to boot. If you're interested in eductating yourself, you want urban heat island and satellite temperature record William M. Connolley 08:40, 8 September 2006 (UTC)
- Hrmm...when speaking about satellite temperature records, you propose to use data accumulated over the last 27 years to make statements about weather patterns on a 4.2-billion-year-old planet? Perhaps you should expand your horizons, as it were, a bit. --The Outhouse Mouse 23:58, 8 September 2006 (UTC)
- If you don't understand how satellite temperature records are used in the understanding of our climate, it wouldn't hurt you to learn something about the subject. Skyemoor 01:03, 9 September 2006 (UTC)
- This would be akin to compressing the lifespan of the Earth down to a year and then looking at the temperature over the last three seconds on December 31 and using that to make conclusions about the previous whole year. --The Outhouse Mouse 11:12, 12 September 2006 (UTC)
- This is false. If you 'compress' in a manner that you speak, you will lose information. The information contained in three seconds is not the same as the information contained in many years. Also, if you were to use the information in the last 3 seconds to predict the next second, it will probably work! That is what scientists are doing. They are not saying "based on the last billions of years, the temperature a billion years from now will be..." They are saying, "based on the drastic changes of temperature in the past X years, the next y (y much smaller than X) will probably follow a similar pattern." Also, by looking at one year I can predict certain things about the earth. For example, I would be able to tell you about day and night in certain areas. Some patterns are highly predictable, others are not.

Milloy as a source of scientific input?? "Sloane", you show all the signs of a political hack. You've shown that you are clearly not a scientist, and are attempting to further a political agenda (with typical extremist name-calling). We know a troll when we see one and it is not William Connelley who is the troll in this thread. Skyemoor 11:23, 8 September 2006 (UTC)
- Skyemoor, I would be very much obliged, if you would demonstrate any facts supporting your accusations. As far as I can see, so far you have been the one mostly engaged in name-calling, not me. Also, calling yourself in plural to beef up your point of view gives it away as an unsubstantiated attack. I will simply ignore your further attacks. Arvin Sloane 07:16, 9 September 2006 (UTC)
- #1 Anyone quoting Milloy is clearly not a scientist. #2 You show no signs of understanding the science. #3 You were the one to start making accusations of trolling. #4 Show me where I called you a name. Skyemoor 03:55, 10 September 2006 (UTC)

Several of Milloy's contentions are simply wrong (e.g., "General Circulation Climate Models are programmed to show warming proportionate to atmospheric carbon dioxide levels"), several are red herrings (e.g., "General Circulation Climate Models do exactly as they are programmed to do" -- ALL computer programs do exactly as they are programmed to do!), and some of the rest are outdated. If you are going to write a new article or make significant changes then you should be more diligent in verifying your sources. Raymond Arritt 12:30, 8 September 2006 (UTC)
- Perhaps, some of Milloy's statements are simplified, since he popularizes scientific opinions as a journalist, though I don't see why it would be polite or appropriate to call any of them "red herrings." Please be assured that I am very diligent in everything I do. Thank you for your advice, however. Arvin Sloane 07:19, 9 September 2006 (UTC)
- The statement I quoted is not "simplified"; it is wrong (as are several others in the list). There's a big difference. Only Milloy can tell us whether he makes these mistakes from dishonesty or from incompetence. Raymond Arritt 22:48, 9 September 2006 (UTC)
- So far, the vote to remove reference to Oreskes is 3 in favor, 2 against. I ask all parties concerned to note that I do not rush to make a change. I also ask you to be honest: that is, not to bring in some friend who doesn't regualry participate in this discussion. (I could have brought 7 or 8 votes immediately this way.) Arvin Sloane 07:27, 9 September 2006 (UTC)
- For what it is worth, I oppose the removal of the ref. Note, however, that Wikipedia almost never counts votes as a means of settling an issue. What is important is the discussion. Other than your personal dislike of the research, what grounds do you have for removing it (the former being impermissible grounds per WP:OR)? The essay was published in Science, and for whatever criticisms I have of it, lack of prominence in the scientific community is not one of them. And Arvin, please sign in. --TeaDrinker 07:52, 9 September 2006 (UTC)
- I oppose ther removal of the ref. Skyemoor 03:55, 10 September 2006 (UTC)
- A historian is well qualified to add up papers and draw a conclusion, she is not making judgements on the science itself. The statement needs a source, and it would be stupid to remove it. If there is a similar reference that gives a contrary implication, that can be added as well. --Michael Johnson 07:59, 9 September 2006 (UTC)
- What, where did that "vote" start to remove Oreskes? You can't be serious! Of course she needs to remain in the article. Hardern 08:08, 9 September 2006 (UTC)

It is a moot point, of course, since we don't decide things by counting votes anyway. --TeaDrinker 22:17, 9 September 2006 (UTC)
Where do you count 2 vs. 3? Besides, it will not be removed. Its too important. On another note, is there a wiki policy against being under the influence when editing? Brusegadi 15:18, 9 September 2006 (UTC)

- No, I am not able to sign in. First page that opens when I come to Wikipedia has me signed in, the next — when I click "edit," for example — already has me logged out, and I can't do anything about it. It has been happening ever since I've been on this station. But this is beside the point: who cares, except you guys, who would like to find something — anything — false about everybody who has guts to stand up against your preconceptions? When it comes to GW "consensus," majority is all you're talking about, and Oreskes' article count is an "important research." When there is a danger that your preferences would be denied by a majority, vote count is suddenly no-no, and the very concept of consensus goes down the drain. Be it your way. I am patient. Solar activity peak has passed, from now on it will be colder and colder, and few years from now you yourself will be scrambling to re-write this article, to save what's remained of your reputations. My guess would be by 2011-2014 you all will be crying wolf again about global freezing. We'll live and see. Arvin Sloane 23:34, 9 September 2006 (UTC)

"Global Warming"?
Michael Crichton doesn't think so, and from what i understand, he's actually a scientist, not just some left winger on the internet. Why does this article ignore his conclusions about "man made" warming?--—(Kepin)RING THE LIBERTY BELL 12:57, 8 September 2006 (UTC)
- Chrichton was a medical doctor before he became an author, and gave up his practice years ago. And this and this hardly qualify as "some left winger on the internet." · j e r s y k o talk · 13:12, 8 September 2006 (UTC)
- Michael Crichton is absolutely right, and he has one huge advantage: he is financially independent, and, unlike government- and UN-subsidized scientists, can say what he really thinks. Arvin Sloane 07:30, 9 September 2006 (UTC)
- So can I. Does that give my views equal credibility with Chrichton's? And if not why not? He writes novels. Big deal. Has he done any orginal peer-reviewed research on this subject? I haven't, and neither has he, so frankly neither of our opinions deserve to be included, unsupported, in a wikipedia article.—Exile 11:40, 13 September 2006 (UTC)

- Actually, support by someone who is not qualified says nothing at all...neither is it positive nor negative. In the linked article, Gore does not discuss the science, but the political reaction to it. For this, arguably, he is qualified. --Stephan Schulz 15:41, 19 September 2006 (UTC)
- Besides, Gore is not claiming anything new, he is just explaining what the scientists are saying and the scientists said that he did a great job. Thus, his views are supported by the vast majority of scientists. Brusegadi 15:52, 19 September 2006 (UTC)
- The linked article was just to show a ridiculous political statement by Gore. Gore's relying on his alleged credibility to make GW a political issue. Gore is not a scientist. Neither is Crichton. Neither, to my knowledge, are publishing original research; they are just stating their support for opposing viewpoints. So why is one vilified while the other is revered? Oh wait, one's in lockstep; the other's not. Bingo. -- LoudMouth 15:57, 19 September 2006 (UTC)
- So why is one vilified while the other is revered? Oh wait, one's in lockstep; the other's not.
- I thought it was because one is accurately stating the consensus opinion of the scientific community and the other is free-lancing on behalf of his usual conservative beliefs.
- Indeed. If by "being in lockstep" you mean "being in good agreement with the considered opinion of the vast majority of competent scientists", and by "being vilified" you mean "being ridiculed for spewing nonsense", you have a point. --Stephan Schulz 17:26, 19 September 2006 (UTC)
- Usual "conservative" beliefs? What the hell? Crichton disagrees, so he's in it for the politics? I guess that's in sharp contrast to Gore, who's clearly just a science buff who moonlighted as Vice President and Senator, and who hopes to be President someday. So here we go again, bringing politics into it. I never said that Gore is "revered" by you people because of his politics - he's revered because he agrees with the groupthink of those who desperately need human-caused GW to be fact as opposed to theory (or myth). -- LoudMouth 17:33, 19 September 2006 (UTC)
- Schulz blathered ..."vast majority of competent scientists", and by "being vilified" you mean "being ridiculed for spewing nonsense"...
Who defines "competent"? And which scientists get to weigh in and be counted as part of the "consensus"? Do physicists and astronomers get to have their say? If there's a list of individual scientists and thier qualifications, I'd love to see it. I'm just curious and would like to verify who this consensus really is. But I'm not going to to take something at face value just because someone says it really loud and pounds his fist. -- LoudMouth 17:43, 19 September 2006 (UTC)
Global Warming - an alteritive hypothesis
Global Warming – An alternative Theory
Introduction
There can be little doubt that global warming is occurring. The current wisdom is that this is due to the Greenhouse effect of global emissions, hence the Kyoto agreement. However there is a simpler and potentially more worrying possibility.
Energy usage
Mankind has become a huge consumer of Energy. Well, physically speaking, this is not possible, because, except by nuclear power, Energy can neither be created nor destroyed. It is simply converted from one form to another – usually heat.
So when you are burning fossil fuels in your car, you are releasing energy stored in the fossil fuels as heat (and kinetic energy – movement, which also ultimately gets converted to heat). Where does this heat go? It would be tempting to think that it is radiated or released into space, but lets think about that. The temperature of space is close to absolute zero, and the rate of heat loss is proportion to the difference in temperature. Historically we have been in approximate equilibrium, which is to say that the heat coming in (from the sun) equals the heat going out (due to difference in temperature). We are not changing the size of the Earth, nor its mass, so any heat we add to the equation must result in a temperature rise until a new equilibrium is reached. So if we are generating say 1% of the sun’s heat, the global temperature must also rise by 1% (nearly 3 degrees Celsius) in order for us to successfully get rid of it into space as fast as we are generating it. That is regardless of any Greenhouse Gas effect (which only makes matters worse).
More bad news
This means that controlling Green House gases will not save us. What is more, it doesn’t matter what the energy source is, unless it is the sun itself (and not historical sun, such as in fossil fuels). Nuclear energy is just as bad as fossil fuels. Wind and Wave energy are just as bad too. The only safe energy in this regard is plant energy, so bio-diesel, plant oils, solar panels and wood burning are all OK, but that is about it. All of this energy has been provided by the sun in its recent history, BUT, of course, we must not reduce the total plant mass, so it must not just be a renewable, but a source that has been renewed. There is no way to cheat.
The good news
The good news is that this is not runaway global warming. If we mend our ways and use the right sources of energy (and that means more forests, albeit farmed and managed), the earth will eventually return to the old equilibrium, except for the effects of greenhouse gasses.
OOO - Own Opinions Only
Dave Mear.
- (A) Wikipedia is not the place for original theories, and (B) the amount of energy beamed to earth by the sun is many orders of magnitude greater than all the energy usage of mankind; man's use of energy is nowhere near what is necessary to affect change on a global scale. Raul654 16:26, 8 September 2006 (UTC)
- (edit conflict) Sorry, this page is not for discussing global warming itself, but for discussing our article on global warming. Please feel free to discuss your theory further, but this isn't the place to do so; I'm sure someone will come and suggest a place where people would be happy to help, though. In the meantime, you've also got a few inaccuracies; for example, the amount of heat radiated away from an object is not proportional to its temperature (see black body for some equations). You may want to work on your theory a bit more. —AySz88\^-^ 16:32, 8 September 2006 (UTC)
- The sci.environment newsgroup would be a great place to propose your theory. Raymond Arritt 16:34, 8 September 2006 (UTC)
- Well it would be except its been done before :-) See-also http://mustelid.blogspot.com/2005/05/global-warming-is-not-from-waste-heat.html (and the earlier post) William M. Connolley 17:22, 8 September 2006 (UTC)
Just a thought. Is this REALLY original?
I have seen this in a (factual) book by Isaac Asimov - that is, the idea that all forms of energy used by humans end up as heat, which must be radiated into space - so the more energy we generate, the hotter we'll get. Think of one possible energy source - solar energy stations in space, beaming the energy to receivers on earth. Now surely if the total energy we receive from the sun increases - shouldn't we get hotter, as the energy is converted to different forms and eventually becomes heat? And wouldn't this also apply to increases in energy conversion on earth - eg from nuclear sources, or fossil fuels? If it's true that "the amount of heat radiated away from an object is not proportional to its temperature " (I don't know, I'm not a physicist) then Asimov seems to be wrong in this case. Just thinking out loud! -- Exile 11:48, 13 September 2006 (UTC)
- The amount of heat radiated is proportional to T^4 (see Stefan-Boltzmann law), not to T (and I'm certain Asimov knew that ;-). Yes, any form of latent or external energy we use (space mirrors, nuclear, anti-matter, fossil fuels...) contributes to the Earth's heat budget. But all these sources are so miniscule compared to solar irradiation that they can be essentially ignored for now. --Stephan Schulz 12:41, 13 September 2006 (UTC)
The connection to Asimov reminded me of the Dyson sphere. — [Mac Davis] (talk) (Desk|Help me improve)

Global Warming's Prolonged Effects
Global warming will effect everyone in the world.
More objective information needed
I think there needs to be more recogninition that more than a "small minority" of scientist disagree on global warming. I think it is important from a credibility POV to not appear so biased in presenting a wiki and its important to remain objective and not emotional. Objectivity and a lack of emotion are hallmarks to great science. I should know, I am an engineer who graduated top of his class and have recently graduated from Oxford law school, not only that but my fiance is a PhD in astro physics at the university of Hawaii. We get pretty steamed when there is bad science out there and to spin science is wrong. I think it is wrong to discount the disenting voices in the global warming debate. I think it is always better to debate and disagree than to not debate at all. And when the wiki is saying only a "small minority of scientists disagree", that is really shutting down that important area of debate. Lets keep the wikis unbiased and factual. Its best for all parties involved.
- The article isn't biased. Please see WP:NPOV especially the section about undue weight. Furthermore, please note that Wikipedia is not attempting to foster debate or stifle debate simply report things in an accurate as possible fashion subject to WP:V and other policies. As such the statement that a "small minority of scientists disagree" is an accurate depiction of the current situation. (And incidentally, good for you and your fiance but none of those degrees have anything to do with the global warming (if you want to make this about personal degree related issues (which are irrelevant anyways) we have a number of climate scientists who have helped write this article and neither an engineering degree nor a law degree are generally considered to be in science.) Now, if you have specific points in the article which you think are inaccurate, you are more than welcome to point them. Please also remember to sign your comments with four tildes like this ~~~~ .

As you can see, this is a featured article with recognized quality. Sources confirming its content abound. You must follow all the proper procedures in order to make changes that will not be promptly reverted. Do not start a revert war, you may be blocked for violating the three-revert rule. Last but not least, I recommend signing all your comments on the talk page by simply typing ~~~~ in the end of your comment. Thank you.--Húsönd 01:27, 13 September 2006 (UTC)
- The article is obviously biased. It doesn't "simply report things as accurate as possible." It is full of unnecessary conjectures and one-sided references; in the eyes of an impartial observer (and I am no conservative) it reads like Al Gore poster. Don't hide behind the alphabetical soup of Wikipedia "policies," everybody is annoyed to death by these smokescreens of arbitrary nothingness. Arvin Sloane 07:10, 13 September 2006 (UTC)
- According to Stephen Colbert, "Reality has a well-known liberal bias". Science is not a matter of liberal or conservative. We report on the science as it is, not on how some (or the other) side wants it to be. If it currently coincides more with Al Gore's view than with Exxon's or Dick Cheney's, that's just how it is, but it's no reason to change the article. --Stephan Schulz 08:44, 13 September 2006 (UTC)
- I don't know (and don't want to know), who is Stephen Colbert. But I would like to know who are "we" — are you representing yourself in plural? If not, what group of people appointed itself judges and custodians of this article, and on what basis? Arvin Sloane 09:16, 13 September 2006 (UTC)

- And 'we' are basing our material on the breadth of the analysis and findings of the world's science academies and organizations, who have embraced these positions after careful deliberation and examination of the evidence. So yes, the scientific critics are a small minority. We do not intend to represent industry or political interests. If you want to contribute in such a way, see Global warming controversy. Skyemoor 13:23, 13 September 2006 (UTC)
- That's a pity for you, but you might have to get used to the idea that Al Gore is correct in a lot of points concerning climatology (though not in all). Btw: If it were Bush who'd say that the US must do a lot more against global warming, he'd been correct likewise. He probably should listen more to his Californian party-friend Schwarzenegger... Hardern 10:55, 13 September 2006 (UTC)
- Although, Al Gore is also incorrect on a lot of his points concerning climatology... — [Mac Davis] (talk) (Desk|Help me improve)
- Does repeating that claim give it a greater sense of Wikiality for you? Or is it more an attempt to create the Big Lie? Because, seriously, there are very few claims by Gore that are even contentious, let alone "incorrect", except among people who are politically-motivated to deny GW claims.
- Al Gore is not a scientist -- he's a shrewd politician. Whether or not his political platform stands to benefit from findings presented in this article is immaterial (BTW, let it be known that climate funding has not suffered under Bush). There has been an observed warming trend in global surface temperatures, colloqially known as "global warming." There is also an observed increase in greenhouse gases over the same time period. And there is a known absorption band in the IR caused by CO2. Just my 2-cents for common sense. LotR 19:29, 19 September 2006 (UTC)

The global average surface temperature has increased by 0.6 ± 0.2 °C since the late 19th century. -- Climate Change 2001: The Scientific Basis, IPCC Third Assessment Report (TAR), page 26.
We estimate that the sun contributed as much as 45–50% of the 1900–2000 global warming... -- Phenomenological solar contribution to the 1900–2000 global surface warming, Geophys. Res. Lett., 33, L05708, doi:10.1029/2005GL025539.
Even the IPCC estimates that there has been a warming influence from the Sun in their radiative forcing summary figure of about 0.25 Watts per meter squared. Adding this 0.25 Watts per meter squared value reduces the percent contribution of CO2 to about 26.5%.
-- What Fraction of Global Warming is Due to the Radiative Forcing of Increased Atmospheric Concentrations of CO2? Professor Roger Pielke Sr., Climate Science
Thus 0.6 °C x 26.5% = 0.16 °C warming from CO2 since the late 19th century.
The temperature effect of increasing atmospheric CO2 is logarithmic -- that is, the per unit effect constantly declines.
Doubling the human contribution to atmospheric carbon dioxide will cause somewhat less than 0.1 °C additional warming.
The average seasonal rise in global mean temperature for the period 1880-2004 has been 3.8 °C between January (12.0 °C) and July (15.8 °C) only to decline again. -- Global Surface Temperature Anomalies National Climatic Data Center
This annual warming is almost 20 times the total temperature increase possible from doubling the pre-Industrial Revolution level of atmospheric carbon dioxide and yet there is no sign of "runaway" water vapor-driven warming.
Of all the things humans should worry about, atmospheric CO2 isn't one of them. We are being told to look in the wrong direction. Why? — (Quoted from www.junkscience.com)
Arvin Sloane, 04:12, 14 September 2006 (UTC)
- Why are you answering for TOHM? You aren't his sock, are you? But anyway: CO2 log - of course; well known. So what? Why the runaway strawman? Its not in the article. Quoting junkscience is a bit of a giveaway. Pielke Sr is in a minority - you can tell that from his blog. Solar stuff... well, its been argued before; S+W is just one more contribution.

I have tried to insert a link to an author who discovered serious flaws in Oreskes essay on the so called "consensus".
- Assuming you are referring to Benny Peiser, his work is self-published, without any formal quality control. And any attempt at verifying his claims has failed. Check out the abstracts he claims disagree with the consensus (as defined by the refined IPCC position). His work is insignificant. If we include it we have to add an equally irrelevant discussion of his errors...this probably goes on to infinity, certainly ad nauseam.--Stephan Schulz 20:21, 18 September 2006 (UTC)
Those in the game know that there no such thing but the interesting thing about Oreskes essay is that it is used by the Alarmist side in order to try to kill the debate. I also therefore question the very silly headline describing the researchers opposing the mainstream IPCC view: "List of scientists opposing global warming consensus" Well, since there are credible scientists opposing IPCC then THERE IS NO CONSENSUS how can they then oppose something that does not exist? It is like writing a "nice murderer" or something.
- Consensus does not require unanimity. The number of (serious, qualified) dissenters is extremely small.--Stephan Schulz 20:21, 18 September 2006 (UTC)

I am worried that the other parts of science are beginning to shake their heads at climate science. It seems that "evidence" are very easy to come by. The same reasoning is simply not possible in other research fields.
- How familiar are you with each of the various models? How familiar are you with the physics behind IR absorbtion in different molecules?
On the other hand they are not politically saturated in the same way. It is beacuse of this, totally impossible to end an article waithout stating that "it is very likely that the observed/measured/calculated/modelled changes are due to anthropogenic influences". To say with the same degree of uncertainty " It is very likely that the observed/measured/cluclated/modeled changes are within the range of normal variations" is simply suicide.
- Not in the US, or Australia. Quite the opposite, actually, because they drag you in front of Senate Inquisition panels to ask why your climate findings are not in line with right-wing political organizations or science fiction writers.
http://www.cnn.com/2004/ALLPOLITICS/02/19/scientists.bush.ap/
The Alarmist church will then crucify you and you can kiss your fundings good-bye. Oh, well science will survive. But humanity will be sent along the wrong track for a long time before it awakens. And next time "sience" cries "the wolf is coming" surely with a higher degree of certainty, nobody will be listening.

The Cooling World
I reverted the link added because besides not belonging here, it is misleading. We should try to improve the article and stop misleading the reader. WMC has shown much evidence that scientific concensus on global cooling during the 70s was non-existent. Scientists made it clear that they were not sure and that they did not have the tools to be sure, etc. Thus, comparing global warming with global cooling is unfair to the reader.

Cutting an argument for citations to published sources

By far the biggest contributor to the natural greenhouse effect is atmospheric water vapour, which accounts for 98% of the effect seen.[citation needed] Again here there is clear evidence of a feedback mechanism at work, with greater evapo-transpiration rates and greater atmospheric water holding capacity.[citation needed] Some models of climate change miss out the water vapour effect, but although this helps simplify the maths,[citation needed] it leaves the validity of the model in question.[citation needed] The nay-sayers quote this repeatedly, attempting the discredit the climate models [7], and disprove the anthropogenic origin of the current trends, but it can clearly be demonstrated that human activities are contributing both directly and indirectly to the increased loading of this overwhelmingly important contributor to climate change.[8]

- "It is wrong from beginning to end," said the Caterpillar decidedly. (Lewis Carroll, Alice In Wonderland) Don't bother trying to find references to support this stuff. Raymond Arritt 21:43, 18 September 2006 (UTC)
- A simple google search for "greenhouse effect" "atmospheric water vapour" yeilds this which states "Though water vapour is not anthropogenic in origin, it is the most important greenhouse gas" in the first paragraph. —Memotype::T 13:47, 20 September 2006 (UTC)
- Further, this states that about 60% of the obvserved greenhouse effect is contributed by water vapor. —Memotype::T 13:50, 20 September 2006 (UTC)
- Yes, as already is summarized in the Greenhouse gases article. Guess I'm not following what point you're trying to make, so it would be helpful if you could clarify. Raymond Arritt 13:58, 20 September 2006 (UTC)
- I guess I figured the OP was looking for sources which showed that water vapour was a major contributor to GW... —Memotype::T 22:32, 20 September 2006 (UTC)
- OK, reasonable enough. A simple link to the Greenhouse gases article would do for that point. If they want the primary sources, there are a couple of oldish papers by Graeme Stephens that I'd be willing to look up (don't recall the journals off the top of my head). A lot of the other stuff -- "98%...", "some models of climate change miss out the water vapour effect..", etc. -- is either flat wrong or so poorly worded as to be meaningless.

What natural causes are there? — Preceding unsigned comment added by 24.52.175.91 (talk • contribs)
Is this addressed in the article?
This seems interesting. Is it addressed in the article? How long will it take someone here to vilify him & "discredit" him? --LoudMouth 13:37, 21 September 2006 (UTC)
- "In particular, the relationship between global warming and hurricanes is still being debated. [9] A draft statement by the World Meteorological Organization acknowledges the differing viewpoints on this issue [29]." Have you ever actually read the whole article or do you fear ritual defilement?--Stephan Schulz 14:18, 21 September 2006 (UTC)
Political Controversy
I am not sure if this is the right place to present this, but perhaps it would be a good idea to present the facts surrounding the "controversy" over Global Warming. I myself am quite convinced of Global warming, but to present the anti-warming arguments together with the pro-warming arguments might serve to enlighten those who are uncertain. I realize this is a political debate more than it is a scientific debate, but perhaps that will be evidenced by the realities at hand. Just my 2 cents.
