2015 Arctic Sea Ice Video
This video shows the evolution of the Arctic sea ice cover from its wintertime maximum extent, which was reached on Feb. 25, 2015, and was the lowest on record, to its yearly minimum, which occurred on Sept. 11, 2015. This year’s yearly minimum was the fourth lowest in the satellite era.
The analysis by NASA showed the annual minimum extent was 1.70 million square miles on Sept. 11, 2015. This year’s minimum is 699,000 square miles (1.81 million square kilometers) lower than the 1981-2010 average.
“This year is the fourth lowest, and yet we haven’t seen any major weather event or persistent weather pattern in the Arctic this summer that helped push the extent lower as often happens,” said Walt Meier, a sea ice scientist with NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
“It was a bit warmer in some areas than last year, but it was cooler in other places, too.”
