I think that the earth is warming, but that it's not going to be catastrophic, and it's not anyone's fault. The earth has had periods of heating and cooling since its creation. Even in just the short time that records of such things have been kept, the temperature has fluctuated. In the '70s, people were freaking out about global cooling, because the temperature was going down. Now it's gone back up, and people are freaking out about global warming. Obviously, if we can do something to help the environment, we should, but to say that we have caused global warming is just silly. And also, I do not remember reading a prophecy in the Bible of the earth being destroyed by melting ice caps. So, I'm not worried.
