Burning remaining fossil fuel could cause 60-meter sea level rise

New work from an international team including Carnegie's Ken Caldeira demonstrates that the planet's remaining fossil fuel resources would be sufficient to melt nearly all of Antarctica if burned, leading to a 50- or 60-meter ...

End-of-summer Arctic sea ice extent is eighth lowest on record

Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have reported. Analysis of satellite ...

Endurance: Explorer Shackleton's ship found after a century

Researchers have discovered the remarkably well-preserved wreck of polar explorer Ernest Shackleton's ship, Endurance, in 10,000 feet of icy water, a century after it was swallowed up by Antarctic ice during what proved to ...

West Antarctic Ice Sheet collapse is under way

The West Antarctic Ice Sheet, which holds enough water to raise global seas by several feet, is thinning. Scientists have been warning of its collapse, based on theories, but with few firm predictions or timelines.

New tipping point discovered beneath the Antarctic ice sheet

A new and worrying way that large ice sheets can melt has been characterized by scientists for the first time. The research focuses on how relatively warm seawater can lap at the underside of ground-based ice, which can accelerate ...

Colossal Antarctic ice-shelf collapse followed last ice age

In a new study that provides clues about how Antarctica's nation-sized Ross Ice Shelf might respond to a warming climate, U.S. and Japanese oceanographers have shown that a 100,000-square-mile section of the ice shelf broke ...
