Arctic Ice gone by 2013?

Do I hear 2080?

Do I hear 2050?

Do I hear 2030?

Do I hear 2013?

This is almost like listening to an auctioneer. Even though the average global air temperature has declined from last year, we still appear to be on our way to an historic low of arctic sea ice:
Most of the cover consists of relatively thin ice that formed within a single winter and melts more easily than ice that accumulated over many years.

Irrespective of whether the 2007 record falls in the next few weeks, the long-term trend is obvious, scientists said; the ice is declining more sharply than even a decade ago, and the Arctic region will progressively turn to open water in summers.

A few years ago, scientists were predicting ice-free Arctic summers by about 2080.

Then computer models started projecting earlier dates, around 2030 to 2050; and some researchers now believe it could happen within five years.

No wonder we're seeing signs of Tories and extraction industries licking their lips, eh? Elizabeth May knows the score and she's calling them out: The Tories don't want to fight global warming. They're ready to welcome it in fact. It might be good in the short term for the Canadian bottom line, but just ask Westmount-Ville-Marie Green Party candidate Claude William Genest why the consequences of unchecked global warming are being deemed a crisis.
