Contrary to popular accounts, very few scientists in the world - possibly none - have a sufficiently thorough, 'big picture' understanding of the climate system to be relied upon for a prediction of the magnitude of global warming. To the public, we all might seem like experts, but the vast majority of us work on only a small portion of the problem.

Believe it or not, very little research has ever been funded to search for natural mechanisms of warming... it has simply been assumed that global warming is manmade. Climate change - it happens, with or without our help.

I finally became convinced that the theory of creation actually had a much better scientific basis than the theory of evolution, for the creation model was actually better able to explain the physical and biological complexity in the world.

Twice I have testified in congress that unbiased funding on the subject of the causes of warming would be much closer to a reality if 50% of that money was devoted to finding natural reasons for climate change.

Man-made global warming was a potential serious threat, and NASA wanted Congress to fund new satellites to study the problem. It was a team effort to get that accomplished.

We have no idea what's natural and what's man made. [...] There is no fingerprint of human-caused warming.
