I once wrote a term paper on climate change for a geology class.
I couldn't prove or disprove human activity being involved, but I did find from my research that at one time in the past the average temperature on Earth was some 14 degrees warmer than it is now. Also that if past patterns repeat, right now the Earth is nearing the end of a 10,000 year warming trend and within 2,000 years will enter a new small ice age. Also, the polar ice caps didn't even exist until a few million years ago.
Take the Earth as a whole. Subtract the 73% that's under water. Subtract the polar ice caps. Subtract the uninhabited/uninhabitable areas. Subtract the deserts. Subtract the wilderness areas. (The U.S. is 38% wilderness). Subtract the undeveloped countries that have no industry. The area that's left where human activity MIGHT affect climate is really very small.
To put it all into perspective, if the entire life of the planet Earth were compressed into one year, man's entire known history would begin at 3 seconds to midnight on December 31.
