Expert: Arctic polar cap may disappear this summer

OSLO, Feb. 29 (Xinhua) — The polar cap in the Arctic may well disappear this summer due to the global warming, Dr. Olav Orheim, head of the Norwegian International Polar Year Secretariat, said on Friday.

The shrinking of the Arctic ice cap has been astonishing, Orheim said in an interview with Xinhua.



“Ice sheet hit the historical low of 3 million square km duringthe hottest weeks last summer, while it covered 7.5 million squarekm on average before the year 2000, ” he said.

“If Norway’s average temperature this year equals that in 2007,the ice cap in the Arctic will all melt away, which is highly possible judging from current conditions,” Orheim said.
