Dramatic Slowdown in Melting of Arctic Sea Ice Surprises Scientists

The melting of sea ice in the Arctic has slowed dramatically in the past 20 years, scientists have reported, with no statistically significant decline in its extent since 2005. From a report: The finding is surprising, the researchers say, given that carbon emissions from fossil fuel burning have continued to rise and trap ever more heat over that time. They said natural variations in ocean currents that limit ice melting had probably balanced out the continuing rise in global temperatures. Howe...
