I think it could be possible for people to have an affect on our climate but I remain highly skeptical. Primarily I suppose because I believe the loudest proponents of mmgw have ulterior motives.
That's pretty much what I agree with. Until these people who shout about Man Mad Global Warming aren't anti-corporation to begin with, then they will NEVER have my trust.
That is until Earth suddenly combusts from all the methane we produced. When that happens, I'll be the one in hell sitting there thinking, "Well, toejam."
