...that's essentially been proven.

Perhaps. But the causality has not! The data strongly suggest that global warming (and cooling) are very long-period cycles controlled by forces far outside the control of man.

Repeat after me:

Man-made Global Warming is a MYTH!
Man-made Global Warming is a MYTH!
Man-made Global Warming is a MYTH!

The data strongly suggest that global warming (and cooling) are very long-period cycles controlled by forces far outside the control of man.

Except that the period of concern is the past 150 years, and particularly the past 25-30. Those long-period cycles don't really exert a significant influence on shorter time-scales.
