Scientists will be looking now to see how well the ice recovers

Arctic sea ice shrank to the smallest area on record this year, US scientists have confirmed.

The National Snow and Ice Data Center (NSIDC) said the minimum extent of 4.13 million sq km (1.59 million sq miles) was reached on 16 September.

The figure shatters all previous satellite surveys, including the previous record low of 5.32 million sq km measured in 2005.

Earlier this month, it was reported that the Northwest Passage was open.

The fabled Arctic shipping route from the Atlantic to the Pacific is normally ice-bound at some location throughout the year; but this year, ships have been able to complete an unimpeded navigation.
