Causes of ice ages[edit]

The lede para for this section isn't as clear as it should be. It needs to be clearer that its talking about ice ages in general, not just the most recent lot William M. Connolley (talk) 11:58, 24 May 2012 (UTC)

"The consensus theory of the scientific community..." Yeah, right. What consensus? I guess that's why his article is locked. — Preceding unsigned comment added by 24.234.24.22 (talk) 19:46, 28 January 2013 (UTC)

There is no source for the first paragraph, other than how dinosaur flatulance may have caused the ice age. What about the first few sentences??? — Preceding unsigned comment added by 199.36.116.81 (talk) 17:02, 24 February 2014 (UTC)

Major Ice Ages[edit]

This section does not measure up rhetorically. It starts by saying there have been 5 major ice ages, then meanders all over regarding naming them - identifying one of them as "minor", and inserting hypothetical causes inconsistently. It's more similar to a stream of consciousness than reflecting clear thinking on the matter. It should be rewritten by someone familiar with the subject matter and ability to keep the subject matter foremost and supplementary information subordinate. — Preceding unsigned comment added by 76.88.1.215 (talk) 10:14, 8 June 2012 (UTC)

This section also starts off by saying "the current ice age" and ends with "we are no longer in an ice age - it ended 10,000 years ago.... but, there is still glacial ice covering Greenland and the poles.." I'm paraphrasing, but this is contradictory. We ARE obviously still at the end of our current ice age. This paragraph is clearly opinion meant to sway people into believing in climate change, and not scientific evidence. — Preceding unsigned comment added by 198.24.120.174 (talk) 04:20, 4 September 2013 (UTC)

No mention of "Icehouse"[edit]

This article surely needs to talk about, or at least link to the article on Greenhouse and icehouse Earth, since an "Ice Age" is only a period within an "Ice House", etc. --Hibernian (talk) 01:45, 11 March 2013 (UTC)

Megafauna Paradox Not Mentioned[edit]

The latest BBC tv series Ice Age Beasts features the "elephant in the room" (pun intended) which is the conundrum of how millions of mammoths and other megafauna managed to survive the colder ice age period compared to the interglacial conditions of today. How did grass manage to grow in Siberia where it doesn't grow today? This paradox needs a mention at least, due to it putting the whole ice age theory into question. (P.S. A more common sense idea imv is that Jupiter's 100,000yr cycle increases the Earth's equatorial tidal strength which can even push warm water into the Arctic Basin). 176.24.226.120 (talk) 21:08, 31 May 2013 (UTC) Alan Lowey

Effects of Glaciation[edit]

The orthodox effects of ice age glaciation is assumed in this article, i.e., ice is moving from somewhere to somewhere and is digging, scraping, and gouging the earth's surface to give us the artifacts that we see today. Nowhere is it explained what is forcing the ice to move. Hopefully, in a classroom, it is not assumed from a vertical wall map that ice is flowing "down?" Isn't the force of the assumed movement of primary interest? 3km - 4km (~11,500 feet) thickness of ice greatly exceeds the average elevation differences in most areas of North America. What is the source of force that is pushing the "moving" ice to "dig," "scrape," and "gouge" the land? Hanging a vertical map on a wall simply does not supply the force! — Preceding unsigned comment added by GQuickstad (talkcontribs) 16:25, 6 September 2013 (UTC)
