As global warming passes certain limits, dire changes will probably become irreversible, the researchers said, including the loss of polar ice sheets and the death of coral reefs.
Scientists have unravelled the secrets of a period 35 million years ago when Earth cooled rapidly, leaving Antarctica shrouded in ice. The findings could help to predict the unstable future of the West Antarctic ice sheet, researchers from the Alfred Wegener Institute say.
Clinging to the underside of ice hundreds of meters thick, strange communities of sea life eke out a living in perpetual darkness. Now, researchers are racing to find and study these creatures before they—and their ice sheets—disappear.
A new satellite finds a surprise: Atmospheric rivers of moisture can dump huge amounts of snow over Antarctica, and now we can track it incredibly closely.
