Antarctic ice sheet warming faster than thought: study
The West Antarctic Ice Sheet, whose melt may be responsible for 10 percent of the sea-level rise caused by climate change, is warming twice as quickly as previously thought, a study said Sunday.
A re-analysis of temperature records from 1958 to 2010 revealed an increase of 2.4 degrees Celsius (36.3 degrees Fahrenheit) over the period — three times the average global rise.
The increase was nearly double what previous research had suggested, and meant this was one of the fastest-warming regions on Earth, according to paper co-author David Bromwich of the Byrd Polar Research Center.
“Our record suggests that continued summer warming in West Antarctica could upset the surface balance of the ice sheet, so that the region could make an even bigger contribution to sea-level rise than it already does,” he said.
Scientists believe the shrinking of the West Antarctic Ice Sheet is responsible for about 10 percent of global warming-related sea-level rise, which if unchecked threatens to flood many coastal cities within a few generations.
