Talk:Late Paleozoic icehouse

Latest comment: 1 year ago by Dudley Miles in topic End of ice age

Correct name?

edit

I would suggest to change the name of this article into Late Paleozoic Ice Age, as that's the name which is most often used in recent publications. Let me just give this paper as an example. Regards, Wenkbrauwalbatros (talk) 16:23, 11 May 2009 (UTC)Reply

In line with Wikipedia naming would be "Karoo glaciation", see the five ice ages, Huronian glaciation, Cryogenian glaciation, Andean-Saharan glaciation, and Quaternary glaciation. Prokaryotes (talk) 22:13, 9 April 2014 (UTC)Reply

Karoo Coal Id like to see a segment on the effect of the Karoo ice age on sea level and north american coal. —Preceding unsigned comment added by 35.14.206.156 (talk) 18:18, 19 February 2010 (UTC)Reply

Connection with Dwyka formation tillites?

The time looks about right. Peter (Southwood) (talk): 15:57, 1 July 2011 (UTC)Reply

Glacial Dynamics

edit

I removed the following because that's just not how glaciers and ice sheets work. "Further pressure would melt the bottom layer, lubricating and letting the snowfield begin moving downslope as a glacier." Ice flows like molasses without ever melting. In cases where there is meltwater at the base of the glacier, that helps lubricate the entire glacier as it slides downhill as well. However, meltwater is not caused by high pressures. Look at a phase diagram of water to see why: even with a few km of ice on top, the pressure only depresses melt temperature by less than 1 degree C. Whereas ice in Antarctica my easily be -10C or colder --- so cold that nothing will melt, even under immense amounts of pressure. And yet, ice in these sheets flows without ever melting. — Preceding unsigned comment added by Citibob (talkcontribs) 12:27, 16 September 2012 (UTC)Reply

References

edit

The article 'Atmospheric oxygen over Phanerozoic time' produced a delayed link that timed out for so long that I put a cite tag in the article before the page would show. It was not actually paywalled but it does show more solid evidence than the other article. I left the tag in because this page does have a relatively low number of references. 71.214.125.228 (talk) 22:03, 30 July 2014 (UTC)Reply

Not sure which link you meant but i added two references. prokaryotes (talk) 00:09, 31 July 2014 (UTC)Reply

End of ice age

edit

The third episode of Chris Packhams new BBC TV series Earth, on the history of the planet, gives a different explanation of the end of the ice age from the one in this article. He said that the Earth was heading for another Snowball Earth and a possible end of plants due to the equatorial swamp forests locking up carbon and causing a disastrous decline in carbon dioxide. (So far his explanation is as in this article but with far more extreme prediction of effects.) He said that the disaster was averted by movement of tectonic plates over the course of the Carboniferous causing the rise of equatorial mountains, destroying the swamp forests and allowing carbon dioxide to rebound, Has anyone come across reliable sources for this theory? If so, it would be worth covering. Dudley Miles (talk) 21:54, 1 August 2023 (UTC)Reply
