FAIRBANKS, Alaska, Sept. 20 — 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.
While satellite tracking of polar sea ice has been done only since 1979, several ice experts who have studied Russian and Alaskan records going back many decades said the ice retreat this year was probably unmatched in the 20th century, including during a warm period in the 1930s. “I do not think that there was anything like we observe today” in the 1930s or 1940s, said Igor Polyakov, an ice expert at the University of Alaska, Fairbanks. |
