As far as global warming, it my be real, it may not be, either way were all going to be dead from WW3 before global warming is a major threat ;)
I don't know if were causing the heat or weird weather or whatever, but I think we've at least put more CO2 into the air with how many bloody people we have on the planet now! Its not the cars that have done it, its the 6billion+ people all taking deep breaths!
