Key Quotes

17 April, 2006

"We are not saying that we don't believe that there can be significant global warming. As John [Christy] said, if you add CO2, something has to change. But things are changing all the time anyway. The big question is: So what? How much is it going to change, compared to other things? And what can you do about it?"

"The media is, almost by definition, most interested in extreme views on the issue, so reporting seldom reveals that broad scientific uncertainty still exists."

Rush Limbaugh interviewed Roy Spencer on his show. Spencer's quotes are in bold:

RUSH: You called yesterday and you wanted to say that my instincts on this global warming as you've heard me discuss them, are accurate. You started a discussion of the calculations here, these climate models, saying that they do not factor -- because it's not easy to do or maybe it's not even possible to factor -- in the role of precipitation and clouds. Could you start there, and basically whatever you were going to say yesterday, go ahead and launch.

DR. SPENCER: Well, I feel like -- and there are a few of us that are like this -- that the Earth has a natural air-conditioning process which occurs that is mainly through precipitation systems. Now, people will think, “Oh, well, you mean when they come by they cool off the air,” and that's not what I'm talking about. It's about the Earth's natural greenhouse effect which is mostly water vapor and clouds. The Earth has a natural greenhouse effect that keeps the surface of the Earth warm.

RUSH: Isn't it true that the majority of greenhouse gases do come from the sources you just mentioned, not manmade sources?

DR. SPENCER: Well, yeah, that's true. Carbon dioxide is a relatively small part of the Earth's natural greenhouse effect.


There's a big problem with [the accepted explanation for the greenhouse effect], though. It makes it sound like the greenhouse effect is what determines the temperature of the Earth, and actually the truth is it's more the other way around. Given a certain amount of sunlight coming in, that is mostly absorbed at the surface of the Earth, weather processes happen which create the greenhouse effect because most of the greenhouse effect is from evaporated water which then turns into clouds, and of course water vapor is a strong greenhouse gas.

RUSH: I dare say I have to interrupt you at this point because most people who only pay attention to the crisis mongers, believe that there is no greenhouse effect other than that created by man. The whole notion of the greenhouse effect has led people to believe that man has totally manufactured this and that it's totally harmful. What you're saying is it's a natural thing that helps keep the Earth's temperatures moderate?

DR. SPENCER: Yeah, that's right. That's right. All the scientists agree with that. What you're talking about is the fact that the media distorts things so much that people don't get the right information. If you're using the media to rely on to get the science about this issue, you won't.

"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."

"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."

Key Deeds

December 12th, 2007

Spencer signed an open letter to the Secretary-General of the United Nations alleging that that the "UN climate conference is taking the World in entirely the wrong direction." It claimed that the process resulting in the IPCC report was flawed, and that if Global Warming really was human-caused that energy would be better spent trying to mitigate the damage it would do, as opposed to trying to stop it. The letter was signed by 100 so-called "Prominent Scientists."

Co-author of Interfaith Stewardship Alliance report critical of the Evangelical Climate Initiative's Call To Action urging a swift response to global warming. The ISA letter argues that "the most prudent response is not to try (almost certainly unsuccessfully and at enormous cost) to prevent or reduce whatever slight warming might really occur." They suggest adaptation instead.
