TheStar.com - Vote on environmental issues, scientists urge

VANCOUVER–More than 120 of Canada's top climate scientists have signed an open letter criticizing Conservative government policy and urging Canadians to vote "strategically" for the environment in next week's federal election.

From the open letter

Many may not realize that even if we immediately stabilized atmospheric greenhouse gases at current levels, the Arctic would still go ice free in the summer, between 10% and 25% of the world’s species would still be committed to extinction, and weather will continue to become more extreme. We have as much warming in store over the next few decades as has already transpired since preindustrial times when the Thames River in England used to periodically freeze over.
