While it’s not yet too late to prevent total collapse, scientists emphasize that only drastic carbon emission cuts can slow the process. If Greenland’s ice sheet melts entirely, the ...

Greenland is covered by more than 650,000 square miles of ice – a massive, frozen ice sheet that blankets the island and slowly flows toward the ocean. But as the climate warms, the ice is melting and ...

A NASA team found signs of the remnants of Camp Century, which shows the extent of Washington’s longtime involvement in the ...

For around 2,000 years, global sea levels hardly varied. That changed in the twentieth century. Sea levels started rising and ...

Greenland is a bellwether of global disruption driven by climate change. The ice sheet is dwindling in real time. Sapphire lakes of meltwater, sometimes miles wide, collect on glaciers in summer.

Tipping points mentioned in the study include collapse of the Greenland and Antarctic ice sheets; coral-reef die-offs; Amazon rainforest loss; lack of winter sea ice in the Arctic; abrupt ...
