Latest Ice sheets Stories
The glaciers along Western Antarctica are among the fastest melting in the world and a new study from researchers at the University of California, Irvine has found that the rate of melt there has tripled in the past ten years.
As the massive ice sheet that once covered much of North America began to melt, icebergs and meltwater would have regularly reached South Carolina and even Florida, according to new research published in the current advance online edition of the journal Nature Geosciences.
Current changes in the ocean around Antarctica are disturbingly close to conditions 14,000 years ago that new research shows may have led to the rapid melting of Antarctic ice and an abrupt 3-4 meter rise in global sea level.
Prevailing models from the melting of the Greenland ice sheet have made the calculation that the ice sheet sits atop hard bedrock. A new study from a team of British and American scientists has thrown out that assumption, however.
The sea level around the coast of Antarctica is expected to rise faster than the projected global rate, experts from the University of Southampton report in research appearing Sunday in the advanced online edition of the journal Nature Geoscience.
Data from the European Space Agency's CryoSat-2 spacecraft has been used to map elevation and elevation changes in both Greenland and Antarctica by a team of researchers from the Alfred Wegener Institute in Germany.
New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated.
A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters.
Ice loss from the Greenland Ice Sheet has increased four-fold over the past four decades, and scientists now report that oceans play a vital role in how quickly the ice sheet will melt and how much total mass will be lost.
