NASA Reveals Record-Breaking Loss of Arctic Sea Ice
August saw the fastest retreat of arctic sea ice on record, according to new NASA data. During that month, sea ice melted at a rate of 32,700 square miles per day, compared with 24,400 square miles per day in 2007. The rate of decline is even more dramatic when compared with the 30-year average rate of decline, 19,700 miles per day.
The accelerated seasonal retreat of sea ice surprised NASA scientists, who expected a more moderate retreat on the tail of a la Niña year. Moreover, the data show that one cold year, when sea ice levels are able return to normal, is not enough to counter the long-term melting of the arctic.
