โ€œIt matters because there is no Climate Crisis. There is no Climate Emergency. Yes, irregular warming is occurring. Yes, it is at least partly due to human greenhouse gas emissions. But seldom are the benefits of a somewhat warmer climate system mentioned, or the benefits of more CO2 in the atmosphere (which is required for life on Earth to exist),โ€ Spencer claimed in an article at the Global Warming Policy Forum.8Roy Spencer. โ€œGlobal warming trend is only half of what climate modellers have predicted,โ€ The Global Warming Policy Forum, April 23, 2021.

“We’re warmer than we’ve been in probably a few centuries, and I think some of that warmth is due to the CO2 we’re producing, but the warming is not nearly as fast as what has been predicted. I think about half of it’s natural, and from a policy standpoint there’s really nothing we could do about the human caused portion of it anyway,” Spencer said.

“For instance, melting on the Greenland ice sheet. That happens every summer, but he makes it sound like it’s due to us,” Spencer said. “Rising sea level in Miami Beach. That is partly natural and it’s partly because Miami Beach was built on reclaimed swampland, which is sinking just as fast as sea level has been rising for the last 150 years.”

“In any event, [temperatures are] not rising nearly as fast as the climate models say it should be rising. And those climate models are what are being used to dictate our future energy policy,” Spencer said.

Spencer summarizes at the start of his talk, suggesting that the warming is “about half” of what is predicted by climate models (note that this article at SkepticalScience counters the idea that models are inaccurate):

“Basically, the variety of observations we have for measuring temperatures, whether itโ€™s in atmosphere or in the ocean, are all pointing to a picture that suggests the warming weโ€™ve seen lately, even if it is due to increasing CO2, which isnโ€™t entirely clear […] the warming is still only about half of what is being predicted by climate models. And remember those climate models are the basis for energy policy,” Spencer began, going on to show “our version of the hockey stick” graph, which he had crafted with the help of John Christy.

He repeatedly suggests that “the climate models aren’t working right,” and also insinuated that the other main source of satellite temperature data “revise[d] their data upward to get more warming.”44โ€œAt the Crossroads IV: Energy & Climate Policy Summit,โ€ The Heritage Foundation, November 30, 2017.

โ€œGlobal warming is not something that we should be terribly worried about from a policy perspective, which is my view.โ€ [58:03]

โ€œThese [models] take marching armies of experts in all different areas.โ€ [58:58]

โ€œNo oneโ€™s an expert with all of that stuff […] itโ€™s almost hopelessly complex.โ€ [59:16]

โ€œThe observations are saying it ainโ€™t warming that fast.โ€ [60:14]

โ€œClearly, the deep layer atmosphere is not warming as much as the models say it should be.โ€ [61:34]

โ€œWe donโ€™t even trust those surface temperatures. Every time they get adjusted, they und up getting a warmer and warmer trend. […] Theyโ€™re trying to force those surface temperatures to warm up to what the models are saying. Theyโ€™re trying to make the measurements fit the theory.โ€ [61:34]

โ€œGlobal warming is not something that anybody will ever feel in their lifetime.โ€ [66:18]

โ€œI am one of the skeptics who believes that adding CO2 to the atmosphere, theoretically, should cause some warming. […] I would expect slow warming to continue in the future–but I wouldnโ€™t bet money on it.โ€ [66:39]

โ€œTheyโ€™re trying hard to make these data sets better match the models. In the matter of the next couple of years, ours will probably have the coldest temperature trend out of all of them, and we will be increasingly marginalized.โ€ [67:12]

Roy Spencer published an article in Forbes titled “Hillary Clinton Boards The Climate Crisis Train To Nowhere” where he makes a number of contentions about climate change. For example, Spencer writes:73Roy W. Spencer. “Hillary Clinton Boards The Climate Crisis Train To Nowhere,” Forbes, October 25, 2016. Archived .pdf on file at DeSmog.

“Global warming and climate change, even if it is 100% caused by humans, is so slow that it cannot be observed by anyone in their lifetime. Hurricanes, tornadoes, floods, droughts and other natural disasters have yet to show any obvious long-term change. “

Eight scientists analyzed Spencer’s article and concluded that it’s overall scientific credibility was “very low.” Their responses are published at Climate Feedback, with overall feedback summarized below:74Analysis of ‘Hillary Clinton Boards The Climate Crisis Train To Nowhere’,” Climate Feedback. Archived November 3, 2016. Archive.is URL: https://archive.is/7sJOS

Kerry Emanuel, Professor of Atmospheric Science, MIT:
The article is inaccurate in several places and conveys that one must choose between solving immediate problems, such as poverty, and long-term risks such as climate change. We can do both, and indeed must do both if we take poverty seriously, since climate change disproportionately affects the poor.

Jim Kossin, Research Scientist, NOAA’s Center for Weather and Climate:
The author makes a number of statements that are not supported by the science or by established scientific process. He is basically playing by a different set of rules than the scientific community at large, which allows him to say anything he wants in order to make his case. A number of statements are misleading and some are obfuscating, particularly in terms of potential impacts of climate change on humans.

Victor Venema, Scientist, University of Bonn, Germany:
This article by Roy Spencer is misleading when it comes to his own work on tropospheric temperature changes and several times severely wrong outside of his expertise. It does not give a fair overview of the state of the science.

Peter Gleick, President Emeritus and Chief Scientist, Pacific Institute:
Almost every claim in this article is scientifically inaccurate or misleading.

Alexis Berg, Associate Research Scholar, Princeton University:
This articles uses a number of misleading statements, logical flaws and unsubstantiated claims to try to defend the erroneous idea that climate change is nothing to worry about, that there is nothing to do about it anyway, and that wanting to address it is all a power play by politicians.

Roy Spencer and John Christy co-released a temperature record analysis, finding “August 2016 was the warmest August in the Northern Hemisphere in the satellite temperature record,” reports the press release.75(Press Release) “AUGUST 2016 AND 2016-TO-DATE ARE SECOND WARMEST,” University of Alabama Huntsville, September 1, 2016.. Republished at NewsRise. Archive.is URL: https://archive.is/CLezm

“While global average temperatures peaked higher this year than they did in 1998, temperatures fell faster this spring and summer to levels that are cooler than they were at this same time of year in 1998,” said Spencer. “We had three months this year that were warmer than their 1998 counterparts, and five that were cooler. There is really no reliable way of predicting what the next four months will do, compared to those same months in 1998.”

Spencer and Christy had released earlier temperature analysis in March, 2016, reports the Washington Post.76Jason Samenow. “February was Earthโ€™s warmest month in the satellite record,” The Washington Post, March 1, 2016. Archive.is URL: https://archive.is/JjVHS

“Iโ€™ve always cautioned fellow skeptics that itโ€™s dangerous to claim no warming,โ€ Spencer told the Post in March. “There has been warming. The question is how much warming thereโ€™s been and how does that compare to whatโ€™s expected and whatโ€™s predicted.”

“It should be clear that the science of global warming is far from settled,” Spencer writes in the report. “Uncertainties in the adjustments to our global temperature datasets, the small amount of warming those datasets have measured compared to what climate models expect, and uncertainties over the possible role of Mother Nature in recent warming, all combine to make climate change beliefs as much faith-based as science-based.โ€

The Guardian notes that the Texas Public Policy Foundation has received substantial funding from both the tobacco and fossil fuel industries, including $65,000 from ExxonMobil and at least $911,499 from Koch-related foundations since 1998, as well as over $3 million from “dark money” groups Donors Trust and Donors Capital Fund.79Dana Nuccitelli. “These are the best arguments from the 3% of climate scientist ‘skeptics.’ Really.” The Guardian, July 25, 2016.

p.18 โ€œPeabody asserted that significant climate change is not occurring or, to the extent climate change is occurring, it is not due to anthropogenic causes. Furthermore, Peabody insisted that any current warming and increased CO2 in the Earthโ€™s atmosphere are beneficial. Based on its position on climate change, Peabody maintained that the externality value of CO2 would most accurately be set at or below zero.โ€ฆโ€

Roy Spencer testified on behalf of coal giant Peabody Energy about the social cost of carbon in front of the Minnesota Public Utilities Commission, along with Roger Bezdek.120BEFORE THE OFFICE OF ADMINISTRATIVE HEARINGS FOR THE MINNESOTA PUBLIC UTILITIES COMMISSION STATE OF MINNESOTA In the Matter of the Further Investigation in to Environmental and Socioeconomic Costs Under Minnesota Statute 216B.2422, Subdivision 3 OAH Docket No. 80-2500-31888 (PDF), June 1, 2015.

Spencer argued that government-run climate change models are inaccurately “biased high” and should therefore not be used to determine the social cost of carbon.

“My testimony will address the validity of climate model projections of global and regional temperatures used in the determination of the social cost of carbon (SCC). Three independent classes of temperature observations show that the climate models used by governments for policy guidance have warmed 2 to 3 times faster than the real climate system over the last 35 to 55 years, which is the period of greatest greenhouse gas emissions and atmospheric greenhouse gas concentrations. Recent research suggests that the climate models are too sensitive to these emissions, and that increasing greenhouse gases do not cause as much warming and associated climate change as is commonly believed [emphasis added].

When politicians and scientists started calling people like me โ€œdeniersโ€, they crossed the line. They are still doing it.

They indirectly equate (1) the skepticsโ€™ view that global warming is not necessarily all manmade nor a serious problem, with (2) the denial that the Naziโ€™s extermination of millions of Jews ever happened.

Too many of us for too long have ignored the repulsive, extremist nature of the comparison. Itโ€™s time to push back.

Iโ€™m now going to start calling these people โ€œglobal warming Nazisโ€.

July 2013

Dr Spencer gave evidence to the US Senate Committee on Environment and Public Works session on climate change. During the hearing (at 3hr 20s), Dr Spencer was asked by Democrat committee member Senator Sheldon Whitehouse: “Do you believe that the theory of creation actually has a much better scientific basis than the theory of evolution.”133Hearing entitled, ‘Climate Change: It’s Happening Now” (Embeded Video), United States Senate Committee Channel.

The question was apparently in reference to an article which Spencer had written several years earlier in which he stated the “theory of creation actually had a much better scientific basis than the theory of evolution.”134Roy Spencer. “Testing Truth with an Open Mind,” The Evolution Crisis. Archived September 6, 2016. Archive.is URL: https://archive.is/Pmo20

Spencer answered that he believed that “evolutionary theory is mostly religion” and that the DNA molecule could not have happened “by chance”. He also claimed that if he was placed in a debate, he would be able to offer more scientific evidence “supporting that life was created” than an opponent could offer that life had evolved.135Hearing entitled, ‘Climate Change: It’s Happening Now” (Embeded Video), United States Senate Committee Channel.

July 2011

In July 2011, a paper co-authored by Spencer was published in the journal Remote Sensing, “[which is] a fine [peer-reviewed] journal for geographers, but it does not deal with atmospheric and climate science,” RealClimate found.136Misdiagnosis of Surface Temperature Feedback,” RealClimate, July 29, 2011. Archived September 6, 2016. Archive.is URL: https://archive.is/TLQ5H

His paper looked at a potential connection between clouds and global warming. The paper received significant media attention, and climate change skeptics claimed that it “blow[s] a gaping hole in global warming alarmism.”137Scott Mandia. “Spencer & Braswell 2011: Proof that global warming is exaggerated? Or just bad science?“, Global Warming: Man or Myth?, August 3, 2011. Archived September 6, 2016. Archive.is URL: https://archive.is/m5oB

Within three days of the publication of Spencer & Braswell’s paper, two climate scientists (Kevin Trenberth & John Fasullo) repeated the analysis and showed that the IPCC models are in agreement with the observations, so refuting Spencer’s claims.138Misdiagnosis of Surface Temperature Feedback,” RealClimate, July 29, 2011. Archived September 6, 2016. Archive.is URL: https://archive.is/TLQ5H

In Andrew Dessler’s view, “[This] paper is not really intended for other scientists, since they do not take Roy Spencer seriously anymore (heโ€™s been wrong too many times). Rather, heโ€™s writing his papers for Fox News, the editorial board of the Wall Street Journal, Congressional staffers, and the blogs. These are his audience and the people for whom this research is actually useful โ€” in stopping policies to reduce GHG emissions โ€” which is what Roy wants.”139Joe Romm. “Climate Scientists Debunk Latest Bunk by Denier Roy Spencer,” ThinkProgress, July 29, 2011.

In response to the flawed peer review that allowed the publication of the paper, the Editor-in-Chief of Remote Sensing stepped down. He had this to say: (PDF)140Wolfgang Wagner. “Taking Responsibility on Publishing the Controversial Paper ‘On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earthโ€™s Radiant Energy Balance” by Spencer and Braswell, Remote Sens. 2011, 3(8), 1603-1613″ (PDF), Remote Sensing (Editorial), September 2, 2011.

“After having become aware of the situation, and studying the various pro and contra arguments, I agree with the critics of the paper. Therefore, I would like to take the responsibility for this editorial decision and, as a result, step down as Editor-in-Chief of the journal Remote Sensing.

With this step I would also like to personally protest against how the authors and like-minded climate sceptics have much exaggerated the paperโ€™s conclusions in public statements. . .”141Wolfgang Wagner. “Taking Responsibility on Publishing the Controversial Paper ‘On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earthโ€™s Radiant Energy Balance” by Spencer and Braswell, Remote Sens. 2011, 3(8), 1603-1613″ (PDF), Remote Sensing (Editorial), September 2, 2011.

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, โ€œOh, well, you mean when they come by they cool off the air,โ€ 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.153Facts, Science Smash the Global Warming Myth” (Transcript), RushLimbaugh.com, February 28, 2007.

According to an August 12, 2005 New York Times article, Spencer, along with another well-known “skeptic,” John Christy, admitted they made a mistake in their satellite data research that they said demonstrated a cooling in the troposphere (the earth’s lowest layer of atmosphere). It turned out that the exact opposite was occurring and the troposphere was getting warmer.161Andrew C. Revkin. “Errors Cited in Assessing Climate Data,” New York Times, August 12, 2005.

“These papers should lay to rest once and for all the claims by John Christy and other global warming skeptics that a disagreement between tropospheric and surface temperature trends means that there are problems with surface temperature records or with climate models,” said Alan Robock, a meteorologist at Rutgers University.162Andrew C.

Spencer appeared in a โ€œGlobal Warming Conferenceโ€ with Jonathan Adler, director of the Environmental Program at the Competitive Enterprise Institute (CEI).
