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

A climate tipping point is a critical threshold where a small environmental change can lead to dramatic and often ...

In two recent studies, researchers suggest a weakening ocean current system is to blame for a persistent cold spot in the ...

The ocean around Antarctica is rapidly getting saltier at the same time as sea ice is retreating at a record pace.

An unprecedented Arctic heat wave caused record high temperatures in Greenland and Iceland, raising major concerns among ...

Real world measurements of how much extra heat the Earth is trapping are well beyond most climate models. That’s a real problem.

First created during the Cold War, Project Iceworm saw the US plan to store hundreds of ballistic missiles in a system of ...

NASA scientists in Greenland took an unprecedented look at Cold War history when surveys found an abandoned "city under the ice." In April, two scientists surveying the Greenland Ice Sheet found ...

The Greenland Ice Sheet is cracking open more rapidly as it responds to climate change. The warning comes in a new large-scale study of crevasses on the world’s second largest body of ice. Using ...

Global warming is causing the Ice Sheet to melt and flow more rapidly, raising sea levels and disturbing weather patterns across our planet. Because of this, precise measurements of its changing shape ...

Here’s how it works. A disturbing new video shows 13 years of melt at the Greenland Ice Sheet. The video was stitched together based on NASA and European Space Agency (ESA) satellite data.
