Arctic landscapes with spots of disconnected permafrost erode faster than those with continuous permafrost, a new study finds ...

To put a price tag on climate change, some approaches focus on whether it made an event more likely, whereas others focus on whether it made an event more severe and damaging. A new study examines the ...

Changes in river chemistry in the northwestern North American Arctic reflect increased acid rock drainage associated with permafrost thaw, an unexpected consequence of Arctic warming.

A global comparison of microbial magnetic minerals unlocks a new tool for glimpsing the future of oxygen in Earth’s changing oceans.

The Upsala Glacier in Argentina, like many of Earth's glaciers, has been thinning and retreating at a rapid pace. According to a new report, worldwide glacier thickness is at a record low. Credit: ...
