My question is always:
If not for Global Warming (capitalized because it's now a religion)
...wouldn't we be locked in one of Earth's many Ice Ages, still?

There is a problem with the figures though. Research is showing that
the CO2 llevels are far higher than they have been during any warm
periods they can measure. I believe it is almost double what it
should be for a peak and it's the highest they've measured going back
nearly a half million years. They are coming up with some pretty
concrete figures as far as the excess CO2 and correlating it with the
temperature rise.

Professor Richard S. Lindzen, the Alfred P. Sloan Professor of Meteorology,
Department of Earth, Atmospheric and Planetary Sciences, would be surprised
to hear that.
