Strange artic melting

A new study funded by the National Science Foundation finds that the western part of the massive West Antarctic Ice Sheet is experiencing nearly twice as much warming as previously thought. An unmannd station (Byrd Polar Research Center) has recorded the temperatures in the west artic ice sheet and demonstrates a marked increase of 4.3 degrees Fahrenheit in average annual temperature since 1958. That is three times faster than the average temperature rise around the globe. "Our record suggests that continued summer warming in West Antarctica could upset the surface mass balance of the ice sheet, so that the region could make an even bigger contribution to sea-level rise than it already does," said David Bromwich, professor of geography at Ohio State University and senior research scientist at the Byrd Polar Research Center. Many people say that it is global warming, but it does not explain why this area is melting 3 times faster then any other ice sheets in the world. While the researchers work to fully understand the cause of the warming at Byrd Station, the next step is clear, he added.” West Antarctica is one of the most rapidly changing regions on Earth, but it is also one of the least known," he said. "Our study underscores the need for a reliable network of meteorological observations throughout West Antarctica, so that we can know what is happening--and why--with more certainty."        http://www.macroevolution.net/antarctic-ice.html
