Arctic ice ebbs to record level - U.S. scientists

Arctic sea ice melted to its lowest level ever this week, shattering a record set in 2005 and continuing a trend spurred by human-caused global warming, scientists said on Thursday.

"It's the biggest drop from a previous record that we've ever had and it's really quite astounding," said Walt Meier, a research scientist at the U.S. National Snow and Ice Data Center in Colorado.

Sea ice freezes and melts seasonally, but never has it ebbed to this small a patch, the data center said in a statement. Compared to 2005, the previous record-low year for Arctic sea ice, this year saw a decrease of more than 386,100 square miles (1 million square km).

That is about the size of Texas and California combined, or nearly five times the size of the United Kingdom, the center said. It is more than double the drop between 2005 and 2002, the previous record-holding year.

"That's a dramatic change in one year," Meier said of this year's sea ice decrease. "Certainly we've been on a downward trend for the last 30 years or so, but this is really accelerating the trend.".......
