Cryosat spots Arctic sea-ice loss in autumn
http://www.bbc.co.uk/news/science-environment-21437680
The Arctic has experienced rapid change in recent years
The dramatic recent decline in Arctic sea-ice cover is illustrated in new data from Europe's Cryosat mission.
The spacecraft, which uses radar to estimate the thickness of marine floes, has observed a deep reduction in the volume of ice during autumn months.
For the years 2010-2012, this is down a third compared with data for 2003-2008.
For winter months, the fall in volume is not so great - down 9% over the same period.
