I am from Canada and we have had very normal cyclical weather for my entire life on this planet. I disagree with blaming 300 - 300 parts per MILLION as driving the worlds climate? It is like blaming global warming on bottled water bottles? Water bottles have increased over this century, are they to blame? We all need to move about, we all need to use the best source of energy to get the job done efficiently and effectively, we all need to be responsible BUT we all need to live, all emissions should be regulated, THAT should be our focus. It can be done responsibly and I actually see a carbon tax as a tax grab. Why not just work towards a cleaner environment and work towards REDUCING ALL EMISSIONS. Blaming carbon is just a witch hunt and doesn't really do what is needed to actually improve air quality.
