Scientists Report Severe Retreat of Arctic Ice

The cap of floating sea ice on the Arctic Ocean, which retreats under summer’s warmth, this year shrank more than one million square miles — or six Californias — below the average minimum area reached in recent decades, scientists reported Thursday.

The minimum ice area for this year, 1.59 million square miles, appeared to be reached Sunday. The ice is now spreading again under the influence of the deep Arctic chill that settles in as the sun drops below the horizon at the North Pole for six months, starting Friday.

The findings were reported by the National Snow and Ice Data Center in Boulder, Colo., and posted online at www.nsidc.org.

Here’s another interesting bit of information that was buried at the end of the story:

Sea ice around Antarctica has seen unusual winter expansions recently, and this week is near a record high.
