Thanks for the defense.

To summarize, I think the Milankovich cycles, solar cycles, thermohaline cycles and geophysical factors such as tectonic movements and volcanism all have a great deal to do with our planet's weather and climate. The exact composition of the atmosphere is a miniscule factor.

Most of the "average temp" data has not adequately taken into account Man's generation of heat with our engines and our effect on terrain with pavement and roofs (heat island effects). If you've ever sat in rush hour traffic in summer on a motorcycle, you know just what I mean.
