Plunge in CO2 put the freeze on Antarctica

Atmospheric carbon dioxide levels plunged by 40 per cent before and during the formation of the Antarctic ice sheet 34 million years ago, according to a new study. The finding helps solve a long-standing scientific puzzle and confirms the power of C0₂ to dramatically alter global climate.

The study by an international team is the first multidisciplinary research of its kind to show that C0₂ was tracking global cooling at that time. It confirms that significant falls in the greenhouse gas result in global cooling, just as rises result in global warming.
