I think we can agree that no matter what we believe there is a chance because of fossil fuel burning we change the climate but it could also be a natural change. We just don't know enough about it. But if there's a chance WE chance it shouldn't we do something about it, just to be sure? The chance there will be a terrorist bomber on the plane you are flying is very very very tiny. Of all the millions of flights, how many have been blown up? Yet the rules and restrictions for flying are ridiculous nowadays. What is the chance your plane will be blown up with liquid explosives? It's next to zero but I can't even take a bottle of shampoo in my handbaggage. This fear of a plane being blown up is also completely "blown" out of proportion by the media. I may take a little ammount of shampoo (or any liquid) in transparant plastic bag now. So, why arn't we a bit more careful about the climate change which could affect millions if not billions on our planet?
