WASHINGTON (Reuters) - Arctic sea ice melted to its second-lowest level this summer, rising slightly from 2007's record but still showing a downward trend that is a key symptom of climate change, U.S. scientists said on Tuesday.

The ice slipped to its minimum extent for 2008 on September 12, when it covered 1.74 million square miles (4.52 million square km), and now appears to be growing as the Arctic starts its seasonal cooldown, the National Snow and Ice Data Center said.

This is 33 percent below the average summer ice cover in the Arctic since satellites began measuring it in 1979 and is less than 10 percent above last year's all-time record low, said Walt Meier, a research scientist at the ice center."
