Canada to benefit from global warming?

A recent British government report predicts, heat waves, hurricanes and flooding for most of the world if steps aren't taken to stop global warming. However the outlook for Canada, Russia, Scandinavia is not nearly as bleak. According to the report these countries could see higher agricultural yields, lower winter mortality and lower heating requirements. It appears that our climatic deficits will actually be addressed by global warming! Not that I support the destruction of the ozone layer but sipping Mai Tais year round by the sunny Niagara River instead of shovelling out all winter appeals to me on some level - but not enough to make me drive a Hummer or support the Harper government.
