I am all for global warming!!!
Canada (and the UK) will benefit from an increase in temperature, longer growing seasons, better climate, abundant resources
then again the argument was made with windmills back in the 80s-90s regarding production vs saved resources. and modern windmills can offset there total production footprint in 3months of usage... then again this was over 20+yrs of development.
Give us 20yrs of actual 'eco-cars' development (not just short run production cars and then scrap the project ie. GM's EV1) and we will see a drastic change in the production method and use of resources.
