File:NASA Arctic Temperature Change 1981-2007.png

Image showing temperature change throughout the Arctic from 1981 until present. Original description from the NASA website (see below):

"Few places on Earth are warming faster than the Arctic. Temperatures have been rising several degrees Celsius per decade (red areas) since 1981. Among the most fundamental questions about Arctic climate change is how the warming will affect the Greenland Ice Sheet. (NASA Map by Robert Simmon, based on data from Josefino Comiso, GSFC.)"
