CO2 emissions melting sea ice

Portland temperatures topped 90F on Monday reminding us that summer is, if not yet here officially, right around the corner. And summer brings big questions for climate scientists like, “how much ice will remain in the Arctic when summer is over?”

As these some recent articles make clear, this past winter was a bad one for the Arctic so sea ice is already weakened, and to make things worse, rising CO2 emissions spell even more trouble:

If you don’t have time to read these articles, these quotes from the Cornwall article puts the American lifestyle in perspective,

“The jet fuel you burned on that flight from New York City to London? Say goodbye to 1 square meter of Arctic sea ice. … The average annual carbon emissions from a U.S. family of four would claim nearly 200 square meters of sea ice. Over 3 decades, that family would be responsible for destroying more than an American football field’s worth of ice … Each person in the United States is responsible for the destruction of 10 times as much ice each year as someone in India.”
