Climate scientists Nicholas Balascio and Francois Lapointe working with an ice auger to drill in the 3.5m thick ice at South Sawtooth Lake, Ellesmere Island, Nunavut Territory, Canada. An ice auger extension is needed because the ice is so thick. Coring lake sediments can only be done after this tedious […]

Satellite imagery has revealed that two of the fastest-changing glaciers in Antarctica are fracturing and weakening faster than ever – the first step towards the glaciers disintegrating and causing sea levels to rise dramatically. Using observations from ESA, NASA and USGS satellites, the researchers explored the Pine Island and Thwaites Glaciers in the […]

An artist’s rendering of undersea earthquake waves.

The method, which they tested in the East Indian Ocean and where they uncovered a decadal […]

If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of […]

Lake Imja near Mount Everest in the Himalaya is a glacier lake that has grown to three times its length since 1990. Credit: Planetary Science Institute/Jeffrey S. Kargel In the largest-ever study of glacial lakes, researchers using 30 years of NASAsatellite data have found that the volume of these lakes worldwide […]

Even if the climate cools, study finds, glaciers will continue to shrink. Nearly 40 years of satellite data from Greenland shows that glaciers on the island have shrunk so much that even if global warming were to stop today, the ice sheet would continue shrinking. The finding, published today, Aug. […]
