Greenland's ice is getting darker, increasing risk of melting

Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely to continue, with the surface's ...

Revealing glacier flow with animated satellite images

Frank Paul, a glaciologist at the University of Zurich in Switzerland, has created animations from satellite images of the Karakoram mountain range in Asia to show how its glaciers flow and change. The images of four different ...

Seeing Antarctica's future more clearly

Do you love to lose yourself in little things? To read every footnote of a book, watch ants in a patch of grass, memorise every mole on a lover's skin?

New method relates Greenland ice sheet changes to sea-level rise

Climate models are not yet able to include full models of the Greenland and Antarctic ice sheets and to dynamically simulate how ice sheet changes influence sea level. Early schemes failed to accurately account for both mass ...

Combined Arctic ice observations show decades of loss

It's no surprise that Arctic sea ice is thinning. What is new is just how long, how steadily, and how much it has declined. University of Washington researchers compiled modern and historic measurements to get a full picture ...

Two lakes beneath the ice in Greenland, gone within weeks

Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly drained away.
