“The ice is just thinner than it used to be. So it doesn’t really matter so much what the summer weather does anymore—the thin ice melts out easier during the summer melt season.”
Apparently the cold weather this summer had nothing to do with the doubling of Arctic ice!
In a new study, detailed recently in the journal Geophysical Research Letters, Stroeve and her colleagues analyzed nearly two dozen computer climate models to determine the extent to which global warming is responsible for the increasing shrinkage of Arctic sea ice.
Her team determined that human activity can be blamed for some 60 percent of the observed rate of decline since 1979, with the rest due to natural climate variability.
