'Super-river' formed the English Channel

(PhysOrg.com) -- A team of Anglo-French scientists studying sedimentary deposits in the Bay of Biscay have concluded that Britain and France were separated by a "super-river" during three periods of glaciations, and they ...

Wind shifts may stir CO2 from Antarctic depths

Natural releases of carbon dioxide from the Southern Ocean due to shifting wind patterns could have amplified global warming at the end of the last ice age--and could be repeated as manmade warming proceeds, a new paper in ...

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. ...

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 ...

Seawater seep may be speeding glacier melt, sea level rise

The melting of ice sheets at the points where they float on and along the world's oceans is a major climate culprit when it comes to sea level rise. But less is understood about the extent of melting that is due to warm, ...
