Studies made by the National Snow & Ice Data Center, at the University of Colorado, Boulder, and NASA satellite images show the extent of Arctic Ocean ice decline from 1979 and August 2012. The ice cover represents a decline of 40 percent in just 32 years when records began being kept. Jennifer Francis a Rutgers University researcher who studies sea ice an weather patterns commented to the New York Times that:
“It’s hard even for people like me to believe, to see that climate change is actually doing what our worst fears dictated. It’s starting to give me chills, to tell you the truth.”
Computer models have been readjusted to take account of the new ice data. The Arctic could be virtually ice-free by the end of this decade. This ice reduction is primarily attributed to human caused greenhouse gases emissions.
Arctic Ice Cover, 1979-2012
It is unlikely the latest NASA imagery, the ice cover data, or climate change will receive much discussion at the current national conventions. Too bad!
