I'm sure those brainiacs just had too much coffee this morning:
WASHINGTON - An already relentless melting of the Arctic greatly accelerated this summer, a warning sign that some scientists worry could mean global warming has passed an ominous tipping point. One even speculated that summer sea ice would be gone in five years...
"The Arctic is screaming," said Mark Serreze, senior scientist at the government's snow and ice data center in Boulder, Colo.
This is what's astonishing: in two years I've watched the minimum prediction for when the Arctic Ocean would be ice-free in the summers go from 2050 to 2012. It's basically a given that the Greenland ice sheet cannot long survive in an environment with sustained ice-free summers in the Arctic, according to James Hansen. And we're looking at that scenario much, much sooner than expected.
