"The core theory says if you double or triple CO2 in the atmosphere, it's going to get warmer," Keith said. "This is something we've known from pretty basic physics and proved with a lot of good science for more than 100 years. That's the reason to worry, not the warming over the last few decades."

Scientists first raised concerns over the warming effects of CO2 in the atmosphere in the 1960s, when the climate was actually cooling. While there's nothing overtly problematic about natural climate change, it?s the rate of change that worries experts.

Approximately 55 million years ago, the climate was warm enough to support alligators in the high Arctic. It took 10 million years for those CO2 levels to decrease to the current level. At humanity's current rate of CO2 production, Keith said, levels will rise back up to that point in only 100 years: 100,000 times faster.
"There is no controversy among anybody, even the skeptics, that the amount of CO2 in the atmosphere is going up -- unless you pick ones that are just nutballs." Keith said. "We know that without any doubt."
