Article clarifications and improvements[edit]

There are a number of changes that would help clarify the area of Ice Age or glaciation in general. These include:

  • This article should not deal with climate change caused by human activities. Ice ages (or glacio-epochs) have been part of Earth history for 3Ga (3 billion years). Human induced climate change is recent and has very little to do with long term glaciation.
  • The summary is very dated and the references are quite old.
  • The summary focuses on recent glacial events (last 2.5 Ma), this is a very small part of the entire history of glaciation. The Pleistocene, holocene, and references to existing ice sheets do not need to be mentioned here.

I hope to update this section soon. Once these changes are in place, further changes in the article will be made. Mark Buchanan (talk) 18:17, 4 August 2014 (UTC)

This article also uses the term 'ice age' for recent glaciations of the Quaternary as well as long term ancient periods of glaciation like the Huronian. I propose changing the wording where 'ice age' is used for Quaternary glacial cycles for better clarity. Mark Buchanan (talk) 22:04, 9 August 2014 (UTC)

Within the paragraph about Negative feedback mechanisms for an ice age, please edit "ice age" to "glacial period." For example "According to research published in Nature Geoscience, human emissions of carbon dioxide will defer the next ice age." That should be "will defer the next GLACIAL PERIOD." This wikipedia article clearly (and multiple times) states the difference between ice ages and glacial periods and that we are currently in an ice age, but interglacial period. Come on, people! Use your brains. — Preceding unsigned comment added by (talk) 23:53, 3 January 2015 (UTC)

Mammals appeared around 10 million years ago on this globe. The Dinosaurs went extinct around 19 million years ago when chuxaba in the yucatan killed them. There is a lot of error in scientific classification. — Preceding unsigned comment added by (talk) 16:54, 6 March 2016 (UTC)

When is next ice age?[edit]

Why does this article fail to estimate when the next ice age will begin? Surely the plethora of sophisticated climate models can determine something which has occurred with such predictable regularity throughout the ages.

Obama science advisor John Holdren says the next ice age would have already begun except that it is being offset by man-made global warming.John Holdren Discusses Ice Age (Is a youtube video of someone actually saying something considered a "reliable source" that someone said something? It would seem to be the most reliable source of all.) — Preceding unsigned comment added by (talk) 18:11, 24 December 2014 (UTC)

If you read the article you'll find out we're in an ice age right now and we have been in it for over 2 million years. NewsAndEventsGuy (talk) 19:05, 24 December 2014 (UTC)
Fine. The next "glacial period" then. When do the omniscient climate models predict the beginning of the next "glacial period", when global temperatures relatively rapidly fall 7 degrees or so? — Preceding unsigned comment added by (talk) 22:36, 24 December 2014 (UTC)
Why does this article fail to estimate when the next ice age will begin? - the answer is, you're a dork, because the article already does what you want: see the section Ice_age#Glacials_and_interglacials. Also, JH doesn't say what you think he said William M. Connolley (talk) 23:06, 24 December 2014 (UTC)

Candidate for FAC?[edit]

A leading expert, Lorraine Lisiecki describes this article on her web site at [1] as "an excellent, easy-to-read introduction to the study of ice ages". Maybe someone who has contributed substantially could take it to FAC. Dudley Miles (talk) 16:38, 6 September 2015 (UTC)

New ice age modulation theory[edit]

A new theory on ice age modulation has been published recently. It suggests that Milankovitch insolation variations regulate interglacials, but only intermittently, because strong northern hemisphere albedo often prevents warming. To overcome this, the paper suggests that CO2 must first reduce to a minimum, which causes flora dieback and the formation of CO2 deserts. This in turn causes dust storm eras, which lower the albedo of the ice sheets and allow an interglacial to proceed.

Modulation of ice ages via precession and dust-albedo feedbacks.

I note the actual ice age page is protected, so I would be grateful if this additional section could be added.
