This abstract sounds like a good source for additional info. -- Alan Liefting (talk) - 04:42, 11 September 2008 (UTC)

Have obtained the paper and added the info to the article. -- Alan Liefting (talk) - 18:57, 16 November 2008 (UTC)

Alan, thanks for starting a much-needed article. May I suggest an edit to the title. To "Climate Change Policy in NZ". Mrfebruary (talk) 10:18, 19 January 2009 (UTC)

Thanks for that. I prefer the current title since the article is about more than climate change policy. Only one section is about policy. If the article grows, and the policy info become a significant part of the article it could the be split out to its own article as a sibling to this one. -- Alan Liefting (talk) - 19:16, 19 January 2009 (UTC)
Cool. I see what you mean. Mrfebruary (talk) 10:23, 20 January 2009 (UTC)

Climate modelling[edit]

We should add a section on climate modelling. "And here is our lovely Karen wearing the latest merino wool number. You won't need it for very long my dears with all this global warming!" ... sorry. -- Alan Liefting (talk) - 03:08, 25 January 2010 (UTC)

I think even with global warming we will still have winters Catonz (talk) 08:21, 4 April 2010 (UTC)
Yep. And possibly colder in cold areas. -- Alan Liefting (talk) - 08:27, 4 April 2010 (UTC)

Climate begun in 1870?[edit]

This article needs a history beyond 1870. I know thats when most records go to and graphs showing global warming usually begin at this date. But if this article is only referring to modern climate change the title should be changed. If it is indeed referring to climate change in New Zealand it should go back as far as possible. It would be a far more interesting article too. Catonz (talk) 09:38, 4 April 2010 (UTC)

I have had the discussion elsewhere about the name of these articles. There are a series of "Climate change in [political entity]" articles. A title such as Anthropogenic climate change in New Zealand or Human induced climate change in New Zealand are unnecessarily unwieldy. Readers would generally assume that it is about anthropogenic climate change. -- Alan Liefting (talk) - 10:10, 4 April 2010 (UTC)
Hmmm this is an encyclopaedia tho right? Is it better to have an inaccurate title or an unwieldily one? Why don’t we just do some digging and find articles showing changes in climate overtime in New Zealand before 1870. That way the article can be accurate and have a short title. The article could have three sections, the first and largest could be ‘Anthropogenic Climate Change in New Zealand’, the second could be ‘Holocene Climate Change’ and the third could be ‘Geological time scale climate change’. There is no doubt New Zealand’s climate has varied in the past, just have a trip around Marlborough Sounds or Fjordland National Park and you will see the evidence. In my opinion such as article would be far more informative and interesting also.Catonz (talk) 09:43, 6 April 2010 (UTC)
I will put a scope of the article contents in the lede. That will hopefully address your concerns. "Climate change in New Zealand" is a distinct top which is partially a subset of Climate of New Zealand. Any climate information prior to anthropogenic climate change should be incorporated into that article. The two articles do need a better cross-linking. -- Alan Liefting (talk) - 05:54, 8 June 2010 (UTC)

NZ Climate Change controversy[edit]

In the article published under the following link it is shown that the temperature trend is valid only for "adjusted data", and not when the measured non-adjusted data are used. The non adjusted data show a pretty stable average with variation of +0.06 per century. See also link: There is apparently a legal proceeding. I cite from the site: <<The NZCSC filed judicial review proceedings against NIWA, requesting the Court to:• Declare the 7SS invalid• Direct NIWA to prepare a valid replacement NZTR>> Lars B R (talk) 17:59, 23 October 2010 (UTC)

What are you arguing should happen here? We do cover the court case in our New Zealand Climate Science Coalition article, but not here or in our NIWA article. --Avenue (talk) 00:21, 24 October 2010 (UTC)
I agree with Avenue. The High Court claim is mentioned in the NZCSC page. IMO its not particularly notable. Mrfebruary (talk) 05:56, 24 October 2010 (UTC)

The very base of the article is the heating trend which is shown to be not true and therefore the article disinforms. How can we tell <<The Royal Society of New Zealand's statement on climate change notes that between 1908 and 2006, there has been a clear upward linear trend in the country-wide average air temperature of 0.9°Celsius.[2]>> and not mention that this is due to adjusted data not measured data? Maybe I am wrong, explain pls why to keep the info that is shown to be wrong? It is not the court part that is relevant.Lars B R (talk) 12:15, 24 October 2010 (UTC)

As far as I'm aware, the heating trend has not been shown to be untrue, but anyway that is somewhat beside the point. Wikipedia is not here to discover the truth, but to report what reliable sources have said. The two blog posts you cite above are not reliable sources. Having said that, NZCSC's activities are part of the public debate over these issues. I don't object to mentioning that NZCSC has challenged the NZ temperature record, as long as we cover this neutrally and without giving it undue weight. --Avenue (talk) 15:30, 24 October 2010 (UTC)
I think that a sentence mentioning NZCSC's challenge of the NIWA temperature record is warranted. I will put something in the article about it. -- Alan Liefting (talk) - 20:46, 24 October 2010 (UTC)

Section from New Zealand Article[edit]

Thought I would drop this section here instead of trying to fit it into a well developed article. I removed it from the New Zealand article as I think it would be more appropriate here. I think a one paragraph summary about climate change under New Zealand#Climate would be useful however (see Talk:New Zealand). AIRcorn (talk) 06:50, 29 January 2011 (UTC)

Environmental Protection
New Zealand's patterns of greenhouse gas emissions are similar to Scandinavian countries, in that land use and land use change and forestry are amongst the most significant contributors.[1] Most of the current 11.9 million hectares of agricultural land had been cleared, representing around 44% of the total land area of New Zealand.[1] Initial attempts to decrease the scale of further deforestation, such as Forestry Rights Registration Act 1983 that created 'forestry rights' have been argued to only be moderately successful.[1] However, they created world class structures of data collection and property rights that made way first for an amendment to the 1949 Forests Act in 1993 and later to the Climate Change Response Act 2002.[1] Forestry came to be seen as main tool in meeting New Zealand's Kyoto Protocol targets.[1] Accordingly, REDD programmes (reducing emissions from deforestation and forest degradation) were implemented, whereby reforestation and deforestation was tied carbon emissions credits and traded (ETS) and commercial carbon-sink forests were planted.[1] Perhaps due to the government's initial control over REDD and the trade in carbon credits there was initially an increase in deforestation and it was not until private forestry owners gained access to the trading scheme and to carbon credits that the scheme started to produce reductions in deforestation.[1]

New Greenhouse Gas Inventory out[edit]

Hi All! There is a new version of the greenhouse gas inventory out covering 1990-2009 – and the current article only talks about to 2007 so it's probably worth changing. I'll try and make a start, but it will take a while as there are a lot of statistics to update. You can find it here:
