I will disagree with you on the \"global warming myth\". Measurements handily indicate a near exponential rise in green house gases in the past 100 years. So I guess the argument revolves around whether or not this massive increase in CO2 and other gases can disrupt the global radiative balance and cause a change in global average surface temperature.
I have to disagree with this in return. We have not been keeping records for a long enough period of to to be able to determine if this is a man-made effect, a natural occurance, or even a normal cycle. Unfortunately, it will take thousands of years of records to probably determine the truth.
From

Yes, there is proxy data used for the older times (ice core samples, tree ring samples, coral samples, etc), but it's all we have right now. There ARE, certainly, natural cycles, and I'm not arguing that. The general trend, however, is a large increase in temperature over the past 100+ years. Again, there will be some natural variation (e.g. the little dip in the middle part of the 20th century), but the overall trend is for rapid increases in average global temperature.[/b]
