I once wrote a term paper on global warming. Granted, this was probably 15 years ago, but what my research found was that going on past patterns, right now the Earth is nearing the end of a 10,000 year warming trend and within about 2,000 years will begin to cool off again.
I also found that at one time in the past, the average temp on Earth was some 14 degrees warmer than it is now. Polar ice caps didn't form until 250 million years ago. (An eyeblink in the Earths 3.6 billion year history).

The area you have left where man is engaging in activities that "might" affect the climate is really very small.
