A new report says that global warming could cost the Californian economy billions of dollars each year, through a combination of rising sea levels, and the increased frequency of wild fires and extreme weather events.

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.
