Arctic sea-ice struggles to build volume

From the BBC:

“There is likely to be about 10,500 cu km of Arctic sea-ice by the end of the week – a volume that would tie for the lowest on record for a November.

It is another indicator of just how warm conditions in the polar north have been of late.

Temperatures of -5C have been logged when -25C would be the norm.

Ice extent – the two-dimensional measure of frozen ocean surface – is also well down, running currently at just over 9.4 million sq km.

Ordinarily, it would be at least a million sq km higher.

The latest volume assessment comes from the Earth-orbiting Cryosat mission.”
