Unusual Arctic heat has been accompanied by a new record low level for Arctic sea ice extent during the normally ice-packed month of January, according to the National Snow and Ice Data Center — over 400,000 square miles below average for the month. And of course, that is closely tied to warm Arctic air temperatures.
“We’ve looked at the average January temperatures, and we look at what we call the 925 millibar level, about 3,000 feet up in the atmosphere,” says Mark Serreze, the center’s director. “And it was, I would say, absurdly warm across the entire Arctic Ocean.” The center reports temperature anomalies at this altitude of “more than 6 degrees Celsius (13 degrees Fahrenheit) above average” for the month.
