BBC NEWS | Science/Nature | Arctic sea ice 'faces rapid melt': "The Arctic may be close to a tipping point that sees all-year-round ice disappear very rapidly in the next few decades, US scientists have warned.
The latest data presented at the American Geophysical Union Fall Meeting suggests the ice is no longer showing a robust recovery from the summer melt.
Last month, the sea that was frozen covered an area that was two million sq km less than the historical average.
'That's an area the size of Alaska,' said leading ice expert Mark Serreze."
