Arctic sea ice shrinks to sixth-lowest extent on record | Environment | theguardian.com

Sea ice cover in the Arctic shrank to one of its smallest extents on record this week, bringing forward the days of an entirely ice-free Arctic during the summer.

The annual sea ice minimum of 5,099m sq km reached on 13 September was not as extreme as last year, when the collapse of sea ice cover broke all previous records.

But it was still the sixth lowest Arctic sea ice minimum on record, and well below the average set over the past 30 years of satellite records. This suggests the Arctic will be entirely ice-free in the summer months within the next few decades, scientists said.
