Iceberg Ahoy!

BBC NEWS | Science/Nature | Antarctic shelf 'hangs by thread'

A chunk of ice the size of the Isle of Man has started to break away from Antarctica in what scientists say is further evidence of a warming climate.

Satellite images suggest that part of the ice shelf is disintegrating, and will soon crumble away.

The Wilkins Ice Shelf has been stable for most of the last century, but began retreating in the 1990s.


ICECAP
The full Wilkins 6,000 square mile ice shelf is just 0.39% of the current ice sheet (just 0.1% of the extent last September). Only a small portion of it between 1/10th-1/20th of Wilkins has separated so far, like an icicle falling off a snow and ice covered house. And this winter is coming on quickly. In fact the ice is returning so fast, it is running an amazing 60% ahead (4.0 vs 2.5 million square km extent) of last year when it set a new record. The ice extent is already approaching the second highest level for extent since the measurements began by satellite in 1979 and just a few days into the Southern Hemisphere winter and 6 months ahead of the peak. Wilkins like all the others that temporarily broke up will refreeze soon. We are very likely going to exceed last year’s record. Yet the world is left with the false impression Antarctica’s ice sheet is also starting to disappear.

Are you trying to confuse the sheeple the facts? :-)

Isn't this an annual "event"? Nor is `the size of the Isle of Man` spectacularly large.

But it should make a great lead for tomorrow`s story about the decline in native manx cat population.
