Although this wasn’t the worst winter on record for retention of Arctic sea ice, a report from NASA and the National Snow and Ice Data Center says that the region is now missing a Texas-sized chunk of the stuff that keeps polar bears alive and cities above sea level. More alarming, the ice that is there is younger, thinner and more fragile than in years past.
National Geographic:
This winter’s maximum Arctic sea ice extent was 5.85 million square miles (15,150,000 square kilometers)—about 278,000 square miles (720,000 square kilometers) less than the Arctic average between 1979 and 2000.
“That’s a loss about the size of the state of Texas,” said Walter Meier of the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado.
“We used to have a winter ice maximum about twice the size of the lower 48 United States,” Meier added.
