Scientists have discovered a large aquifer, the size of Ireland, near the surface of the Greenland Ice Sheet. “This was a big surprise,” said Jason Box, a researcher for the Geological Survey of...

We’ve all heard it: Arctic sea ice is melting. Sea ice is thinner year to year and there is less of it. In 2007, scientists observed a nearly 50 percent loss of summer ice as compared to 1980....

In recent years with sharp summer sea ice decline, the Arctic seems more sensitive to climate warming than elsewhere on Earth. But are other frozen features of Earth changing too? Notably, most of...

Much talk surrounds the deterioration of glaciers and ice sheets—particularly, how they are thinning and losing mass with global warming; but the mechanisms are complicated and scientists want to...

Although Arctic sea ice extent did not set a low record this year, it’s still clear that there is less sea ice than there used to be. Scientists are keeping a close eye not only on the dwindling...

Does melting of the East Antarctic Ice Sheet (EAIS) pose a threat to sea level rise? Studies of the ice melt that fuels sea level rise often focus on the prominent warming and melting of glaciers...

Have you been skiing in the Western U.S. and been surprised by brown snow? We recently talked to a research team that studies these coats of dirt. The dust storms that cause dusty snow appear to be...

Most people picture the Arctic Ocean as miles upon miles of thick sea ice. This icy expanse has become threatened as Arctic sea ice shifts from mainly old ice to much younger, thinner ice. How...

After a cool Arctic summer, sea ice at the North Pole has recovered somewhat from last year’s record low extent. While this is a welcome pause in the downward trend of sea ice extent, some are...

Scientists take ice core samples in cold, windy, and forbidding environments. After drilling through solid ice to...
