Atmospheric rivers linked to melting Greenland ice sheet

Atmospheric rivers—long, concentrated flows of moisture in the sky—are a key factor in the complex conditions accelerating glacial melting over northern Greenland, according to new research from the University of Wisconsin–Madison.

Elegantly modeling Earth's abrupt glacial transitions

Proxy data—indirect records of the Earth's climate found in unlikely places like coral, pollen, trees and sediments—show interesting oscillations approximately every 100,000 years starting about one million years ago. ...

Models oversimplify how melting glaciers deform land

Around 21,000 years ago, ice sheets retreated from the Northern Hemisphere, and great swaths of land were unburdened by the weight of glaciers. Even today, Earth's shape is still changing as the land rebounds, causing effects ...

Glaciers flowed on ancient Mars, but slowly

The weight and grinding movement of glaciers has carved distinctive valleys and fjords into Earth's surface. Because Mars lacks similar landscapes, researchers believed ancient ice masses on the Red Planet must have been ...

Ice lost, island found?

The eastern coast of Antarctica has lost most of the Glenzer and Conger ice shelves. In the process, it gained what is likely an island. If confirmed, the unnamed island would be one in a series of islands exposed in recent ...
