Antarctica was once downright balmy, lush with plants and lakes, but not any time recently. Despite all of the climate change and global warming of the last few million years, the continent has been a barren, cold desert of ice.
What might we expect there in the future as Earth's atmospheric concentration of carbon dioxide grows? More of the same. Antarctica's ancient lake deposits have remained frozen for at least the last 14 million years, suggesting that the surrounding region, the East Antarctic Ice Sheet, or EAIS, has likewise remained intact.
