Well what do you know? Just as I've said many times on the arguement of climate change... and some of you think this is just an election issue? And people want to take a gamble against what we already know of the science with their lives and their children's lives??
And for those who want to argue that this will benefit us by expanding Canada's agricultural zone — give your heads a shake. The climate might seem to expand the zone for growing as for warmer northern temps, but that doesn't mean land that hasn't been farmed before will give predictable yields. And what are we going to do? Clear more forest to make way for more farming? Forest that we need to help recycle the carbon in the atmosphere which is a large part of this problem?
Moreover, world food shortages will no doubt mean very high prices at the grocer. There is a lot we need to import aside from our grains, or perhaps many of you are comfortable living on mostly a bread diet? Well, who knows how this will effect our agriculture, but whatever the case the consequence over all will be very unpleasant.
Case you don't realize it urban cancer sprawl will kill agriculture before global warming/cold so while we are going hungry from no agricultural land we can contemplate the other problems.
