“Scientists debate polar sea-ice opposites”



Arctic sea ice has passed its minimum summer extent, say polar experts meeting in London.

The cover on 17 September dipped to 5.01 million sq km, and has risen slightly since then, suggesting the autumn re-freeze has now taken hold.

This year’s minimum is fractionally smaller than last year (5.10 million sq km), making summer 2014 the sixth lowest in the modern satellite record.

The Antarctic, in contrast, continues its winter growth.

It is still a few weeks away from reaching its maximum, which will continue the record-setting trend of recent years.

Ice extent surrounding the White Continent has just topped 20 million sq km.


Extreme climate is appearing at the Poles.
