2016年，北极冰盖面积到达历史倒数第二低水平，与2007年并列。
截至9月10日，海冰范围维持在414万平方公里，相比于2012年同样低的339万平方公里。
北极海冰在每年的秋冬季节增加，在春夏季节开始融化。
长期以来，被认作地球气候系统变化的敏感指标。
海冰范围由美国国家冰雪数据中心（ NSIDC ）在科罗拉多州Boulder记录，利用卫星测量。

Second lowest minimum for Arctic ice

Arctic ice cover in 2016 reached the second lowest minimum on record, tied with 2007.
The sea-ice extent on 10 September stood at 4.14 million sq km, some way short of the 3.39 million sq km record low in 2012.
Arctic sea-ice cover grows each autumn and winter, and shrinks each spring and summer.
It has long been regarded as a sensitive indicator of change to the Earth's climatic system.
The ice extent has been tracked by the US National Snow and Ice Data Center (NSIDC) in Boulder, Colorado, using satellite measurements.
