Arctic Sea Ice Reaches Lowest Level on Record

The smallest extent ever recorded for the month of July

ANCHORAGE, Alaska —

Satellite images show Arctic sea ice in July reached its lowest level since 1979, according to researchers at the National Snow and Ice Data Center in Colorado.

"What we are seeing here is certainly the sea ice cover is responding to climate change, the Arctic is getting warmer and the sea ice is responding to that," Director Mark Serreze said during a phone interview.

The previous record low for July was 2007. That year went on to be the lowest year on record, and analysts say this year could break that record.

A shift in weather patterns during the last two weeks of July slowed down the sea ice loss.

Scientists say the loss of sea ice is having a huge impact on wildlife in the arctic, especially polar bears and Pacific walrus, marine mammals that spend most of their time living and feeding out on the sea ice.

"Remember the haul out at Point Lay last year, because there was no ice around for them to sit on," Serreze said.

Tens of thousands of Pacific walrus hauled out onto dry land last year and federal officials are concerned that it could happen again this year.

The Average ice extent for July 2011 was 3.06 million square miles, which is 81,000 below the previous record low for the month.
