A joint study by NASA and the University of Irvine in California confirms that the western Antarctic ice sheet is melting. The process is now irreversible, and will culminate in an initial rise of around 1.2 meters in sea level. The only good news is that the process will take hundreds of years to complete.
According to glacier expert and study coordinator Eric Rignot, not only is Antarctica’s ice melting faster and faster, but the process is no longer reversing even if the temperature drops again.
Rignot and his team have collected data on the area within the Amundsen Sea, west of the frozen continent. According to data from the last 40 years analyzed in the study, the glaciers in this area have passed their point of no return. Its ice flows faster and faster, and the height above sea level decreases.
via The ice of Antarctica has begun to melt irreversibly.
