[:ja]NASAとコロラド大学は、1978年の人工衛星による観測開始以降、2016年9月10日の北極海の海氷が、2007年に次ぐ最少面積を記録したと発表しました。

No.34: 北極海の解氷池でもご紹介しましたが、真夏の北極海の海氷面積は1970年代から4割も減少していることがNASAの研究でわかっています。

[Earthview Wonders][Video] No.81: Minimum Arctic Sea Ice

NASA and the University of Colorado reported that since the beginning of satellite monitoring in 1978, the area of the Arctic Sea ice have reached its annual lowest on Sept. 10, 2016.

As introduced in No.34: Melt Ponds of Arctic Sea, it is clarified from NASA’s research that sea ice at the peak of summer covers 40% less area than it did in the late 1970s.[:en][Earthview Wonders][Video] No.81: Minimum Arctic Sea Ice
