Learning About Climate Change and Ice Sheet Melting From Ocean Sediments
About 18,000 years ago the world's carbon dioxide levels increased leading to melting of ice sheets. NSF-funded scientists published a new study on the melting of the now-extinct Cordilleran ice sheet, giving insight into what may happen to the Greenland and West Antarctic ice sheets in the face of current climate change.
