A new paper that uses the

temperature record from Byrd Station, a scientific outpost in the center of the West Antarctic Ice Sheet (WAIS),

 says that the western part of the ice sheet is experiencing nearly twice as much warming as previously thought.

The temperature record from Byrd Station shows an increase of 4.3 degrees Fahrenheit in average annual temperature since 1958, three times faster than the average temperature rise around the globe.  If those older temperature readings are accurate, this temperature increase is nearly double what previous examinations have suggested.
