Chicago (IL) – NASA’s Ice, Cloud and land Elevation Satellite (ICESat) provides new clues about the presence of ice in the Arctic and you already know the picture isn’t pretty. Critical thick ice coverage has dropped by a staggering 595,000 square miles, more than the land size of the U.S.’ largest state - Alaska - in just four years.
NASA found that Arctic sea ice is thinning much faster than previously thought. The area covered by thick ice, which is ice that survives several summers, apparently decreased by 42%. That number translates into 595,000 square miles, which exceeds Alaska’s 570,374 square miles and is more than twice the size of Texas (260,914 square miles), almost four times the size of California (155,973 square miles) or about ten times the size of Georgia (57,919 square miles).
