No, no there aren't. There are a few, here and there. There are far, far more that support it. Even this article which tries to claim otherwise in the face of facts supports this: http://www.dailytech.com/Survey+Less+Than+Half+of+all+Published+Scientists+Endorse+Global+Warming+Theory/article8641.htm
6% deny global warming. From the way it's spun, that is probably an exaggeration, but even if it isn't, that's pretty tiny.
Please explain why this is.
> As to people being stupid; do you know how dumb the average person is? By definition, half the human race is dumber than that.
Technically, that is not true, although it may be approximately true. If you want to take an elitist position about how clever you are, perhaps you should not state that as being true.
