When she returned to Alaska, Mitchell asked the same question of glaciologist Martin Truffer, who also works at UAF’s Geophysical Institute. He said no, Himalaya glaciers […]
There are two primary causes of global mean sea level rise — added water from melting ice sheets and glaciers, and the expansion of sea water as it warms. The melting of Antarctica’s ice sheet is currently responsible for 20-25% of global sea level rise. But how much of a role will it play hundreds of […]
Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm – once big enough to stretch across the Atlantic Ocean from Boston to Portugal – is shrinking out of existence as seen in pictures of Neptune taken by NASA’s Hubble Space Telescope. Immense dark storms on Neptune […]
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet. It’s also thought to be among the most stable, not gaining or losing mass even as ice sheets in West Antarctica and Greenland shrink. But new research, […]
