Submission + - Arctic to be ice-free within FIVE years, not 40

OriginalArlen writes: The BBC is reporting new research into Arctic warming to be presented at the fall American Geophysical Union meeting which describes current models of arctic sea-ice response to warming as far too conservative. The work predicts that albedo feedback, together with a greater heat input from warmer ocean currents, will lead to ice-free summers as early as 2013. This would go a long way to explaining the dramatic and accelerating loss of sea-ice in the summer of 2007, which is merely the latest in a progressively widening gap between modeled and actual sea-ice loss (as well as presenting a nicely testable short-range prediction.)

Whilst sea-ice obviously doesn't raise the sea level when it melts, a similar runaway feedback that lead to significant reductions in the Greenland or Antarctica ice sheets would cause a 6-7m sea-level rise, indisputably catastrophic for human society as well as the polar bears.

It is masked but always present. I don't know who built to it. It came before the first kernel.
