Well, if it was on CBC it must be true. If you are going to be of such unsound mind to believe every thing you hear, you should turn off all TVs, radios and above all your computer.
First, how did they prove it? How did they attribute temperature variations if any to MANMADE CO2? And 3C is huge. Those are numbers which even the ecotards are saying won't happen for decades if not centuries. But it has happened overnight in BC --- amazing.
But, even if you believe the theory, how will us reducing a little bit here in Canada and killing our economy and putting 25% of us out of work and taxing the sh-it out of us going to counteract the tonnes of CO2 being dumped in the atmosphere by China? CO2 doesn't restrict itself to borders so CO2 anywhere would (if you believe the theory) have the same effect globally.
3C is huge? How much do you really think you'd notice the difference between minus 50C and minus 47C?
