Fossilized leaves hold evidence of a sharp increase in carbon dioxide levels as the Antarctic ice sheet began to shrink 23 million years ago, a new study finds. This magnified image of a fossilized Litsea calicarioides leaf clearly shows the stomata, through which leaves take in CO2 and release oxygen. (Tammo Reichgelt/Lamont-Doherty Earth Observatory)

Ancient Leaves Link Loss of Antarctic Ice to a CO2 Spike

Twenty-three million years ago, the Antarctic Ice Sheet began to shrink, going from an expanse larger than today’s to one about half its modern size. Ancient fossilized leaves retrieved from a lake bed in New Zealand now show for the first time that carbon dioxide levels increased dramatically over a relatively short period of time as the ice sheet began to deteriorate.

Red Flags Over the Arctic’s Future

A new white paper reviews climate impacts already underway in the Arctic, and examines further changes expected to take place even if the world meets the goals of the Paris Agreement. It will be presented today at a meeting at the White House of national-level science ministers and advisors from around the world.
