NASA study examines Antarctic sea ice increases

NASA and British Antarctic Survey scientists have reported the first direct evidence that marked changes to Antarctic sea ice drift caused by changing winds are responsible for observed increases in Antarctic sea ice cover in the past two decades. The results help explain why, unlike the dramatic sea ice losses being reported in the Arctic, Antarctic sea ice cover has increased under the effects of climate change.

Global climate models abound. What is harder to pin down, is how a warmer global temperature might affect any specific region on Earth. Researchers have now made the global local. Using a combination of climate models, they predict how different greenhouse gas scenarios would change the face of Greenland and impact sea level rise.
