Arctic ice cap sustains increasing melt rate

This year's melt rates are in line with a sustained decline of the Arctic ice cover.

Last year, the ice cap over the Arctic Ocean shrank to a record low. This year's melting season won't be as extreme, but NASA scientists say the long-term trend is moving strongly downward.

This year's melt rates are in line with a sustained decline of the Arctic ice cover, which has been monitored by NASA for several decades.

In the 1980's the ice cap was about the size of the lower 48 states. It's lost about half its size since then and scientists now say we might see an ice-free Arctic in 30 to 50 years.
