Roy Spencer quotes:

I would wager that my job has helped save our economy from the economic ravages of out-of-control environmental extremism. I view my job a little like a legislator, supported by the taxpayer, to protect the interests of the taxpayer and to minimize the role of government.

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.

We are now at the point in the age of global warming hysteria where the IPCC global warming theory has crashed into the hard reality of observations.

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.

Temperature measurements in the arctic suggest that it was just as warm there in the 1930's...before most greenhouse gas emissions. Don't you ever wonder whether sea ice concentrations back then were low, too?

Nature is not static, but causes its own, internally-generated changes - both in climate and in biological systems.

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

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.

Al Gore likes to say that mankind puts 70 million tons of carbon dioxide into the atmosphere every day. What he probably doesn't know is that mother nature puts 24,000 times that amount of our main greenhouse gas-water vapor-into the atmosphere every day and removes about the same amount every day. While this does not 'prove' that global warming is not man-made, it shows that weather systems have by far the greatest control over the Earth's greenhouse effect, which is dominated by water vapor and clouds.

Politicians and some of the scientists like to say that there's a consensus now on global warming or the science has been settled, but you have to ask them, what is there a consensus on? Because it really makes a difference. What are you talking about? The only consensus I`m aware of is that it's warmed in the last century. They completely ignore the fact that there's this thing called the Oregon petition that was signed by 19,000 professionals and scientists who don't agree with the idea that we are causing climate change.

All scientists should be skeptics. The reason why is that, even with the best of scientific measurements, we can come up with all kinds of explanations of what those measurements mean in terms of cause and effect, and yet most of those explanations are wrong. It's really easy to be wrong in science ... it's really hard to be right.

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...

It is well known that strong to violent tornado activity in the US has decreased markedly since statistics began in the 1950s, which has also been a period of average warming. So, if anything, global warming causes FEWER tornado outbreaks...not more. In other words, more violent tornados would, if anything, be a sign of 'global cooling,' not 'global warming.'

We see something change in our climate and we blame ourselves ... I don't think we understand what happens. We can watch it happen on the (climate) models, we know it happens, but we don't know for sure how it happens.
