I Guess That There's Always a First Time - NOT!

The earth is over four and a half billion years old and there is no evidence whatsoever of there ever having been a runaway greenhouse effect, this despite the fact that atmospheric CO2 levels have at various stages been many multiples of what they are presently. WHAT, PRAY TELL, is so difficult to understand here?

As I'm sure the environmentalist will be quick to point out... the industrial revolution and effects of modern industrialization are but a infinitesimal segment of those 4 billion years. And just look at the environmental impact on the earth's eco system.

Am I close?

Yeah, you are. And I would point out to them that the earth has only warmed some .8 of a degree Celsius, that the U.S. environment has actually gotten much cleaner over the past 3 decades, and that the pre-industrial era wasn't exactly a picnic, either (tons and tons of cow manure in city streets, bad air quality from burning wood, pitiful life spans, etc.).
