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 ...

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.

Greenland’s massive ice sheet is losing ice at an accelerating rate, with scientists warning that a global temperature rise of just 2°C could trigger irreversible collapse. The loss of 230 ...

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 ...

it is more vulnerable to melt than Greenland's land-based ice — precariously so in West Antarctica. In 1978, glaciologist John Mercer warned that rising carbon dioxide levels could trigger the ...
