Spencer published The Great Global Warming Blunder: How Mother Nature Fooled the World's Top Climatologists which is prominently advertised on his blog.
Apart from concluding that global warming is likely caused by a natural cycle, Blunder poses the question, that "maybe putting more CO2 in the atmosphere is a good thing."

Spencer published Climate Confusion: How Global Warming Hysteria Leads to Bad Science, Pandering Politicians, and Misguided Policies that Hurt the Poor in 2008.
Confusion is described as "forsaking blindingly technical statistics" about global warming to describe the issue in "simple terms." [10]

Roy Spencer appeared on the The Great Global Warming Swindle to talk about the "Great Science Funding Conspiracy." Spencer claims that "climate scientists need there to be a problem in order to get funding."
Swindle received critical response from the scientific community, including a letter addressed to ABC signed by thirty-seven British Scientists that claimed "the misrepresentations of facts and views, both of which occur in your programme, are so serious that repeat broadcasts of the programme, without amendment, are not in the public interest. In view of the seriousness of climate change as an issue, it is crucial that public debate about it is balanced and well-informed."
ABC Australia’s Tony Jones also brings the film's scientific accuracy into question in an interview with the film’s director, Martin Durkin.

Roy Spencer was interviewed on Rush Limbaugh's Show. See an excerpt below: [11]
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.

Spencer is listed as a signatory to a 2007 open letter to UN Secretary General Ban Ki-Moon that denied man-made climate change. [12]
The letter states that "it is not possible to stop climate change, a natural phenomenon that has affected humanity throughout the ages."
