Greenland’s Ice Sheet Collapse Could Be Closer Than We Think The collapse of the world’s second-largest ice sheet would drown cities worldwide. Is that ice more vulnerable than we know?

Greenland’s ice-covered landscape looks like an immovable block on satellite maps. Yet the story beneath its center suggests ...

Greenland is renowned for its substantial ice sheet. It appears on satellite maps as a massive, immobile, frozen block. But a ...

As the Cold War intensified at the end of the 1950s, the U.S. Army devised a plan to build a sprawling launch site for nuclear missiles — underneath the ice in Greenland. Dubbed "Project Iceworm," the ...

Earth’s major climate goal is too warm for the polar ice sheets, study says If Earth stays at its current levels of warming — below policymakers’ goal of 1.5 degrees Celsius — polar ice ...

The left map illustrates the cumulative melt days on the Greenland Ice Sheet for the 2025 melt season through June 30. The ...

A salty surge in the Southern Ocean is melting Antarctic sea ice from below — and causing dramatic changes scientists didn’t see coming.

When ice gets trapped on land as giant ice sheets, it causes the sea level to change, but it doesn’t change by the same amount all around the planet.

Searching for the source of these higher sea levels takes us to the poles. In a climate similar to today, the Antarctic and Greenland ice sheets retreated, raising global sea level.

An ancient glacier high in the French Alps has revealed the oldest known ice in Western Europe—dating back over 12,000 years to the last Ice Age. This frozen archive, meticulously analyzed by ...

For more than a century, a patch of cold water south of Greenland has resisted the Atlantic Ocean's overall warming, fueling debate among scientists. A new study identifies the cause as the long ...
