Credentials

Background

Roger Pielke Jr. is a climate science policy writer working at the University of Colorado Boulder. Pielke Jr.’s academic degrees are in mathematics, public policy, and political science.

According to his bibliographic notes, he started studying extreme weather and climate in 1991 at the National Center for Atmospheric Research in Boulder, CO. He discusses his views on climate policy in the book The Climate Fix (Basic Books, 2011).4“STATEMENT OF DR. ROGER PIELKE, JR. to the COMMITTEE ON ENVIRONMENT AND PUBLIC WORKS of the UNITED STATES SENATE HEARING on CLIMATE CHANGE: IT’S HAPPENING NOW 18 July 2013” (PDF), July 19, 2013. Reprinted by Science &  Public Policy Institute. Archived .pdf on file at DeSmog.

While Pielke Jr. argues that he is not a climate change skeptic, and accepts that man-made climate change is a real problem, he has consistently opposed the idea that extreme weather events and climate change are connected. Pielke’s father, Roger A. Pielke Sr., is also an outspoken critic of the United Nation’s Intergovernmental Panel on Climate Change. Pielke Jr. has described research showing the link between extreme weather and climate change as “zombie science.”5The FP Guide to Climate Skeptics,” Foreign Policy, February 26, 2010.

Criticism

Joe Romm at ThinkProgress writes that “the websites that most prominently feature or reprint Pielke’s attacks are climate denial sites like WattsUpWithThat and ClimateDepot.”

Romm describes him as “probably the single most disputed and debunked person in the science blogosphere, especially on the subject of extreme weather and climate change.” Romm also notes that Roger Pielke Jr. was included on Foreign Policy‘s 2010 “Guide to Climate Skeptics” — something that Pielke informed FP that he strongly objected to.9Joe Romm. “Obama Science Advisor John Holdren Schools Political Scientist Roger Pielke On Climate And Drought,” ThinkProgress, March 3, 2014.

Stance on Climate Change

December 2, 2016

Writing at The Wall Street Journal in an article titled “My Unhappy Life as a Climate Heretic,” Roger Pielke Jr. declared:12Roger Pielke Jr. “My Unhappy Life as a Climate Heretic,” The Wall Street Journal, December 2, 2016. 13Marc Morano. “Extreme Weather expert Dr. Roger Pielke Jr.: ‘My Unhappy Life as a Climate Heretic’,” Climate Depot, December 3, 2016.

“I believe climate change is real and that human emissions of greenhouse gases risk justifying action, including a carbon tax. But my research led me to a conclusion that many climate campaigners find unacceptable: There is scant evidence to indicate that hurricanes, floods, tornadoes or drought have become more frequent or intense in the U.S. or globally. In fact we are in an era of good fortune when it comes to extreme weather. This is a topic I’ve studied and published on as much as anyone over two decades. My conclusion might be wrong, but I think I’ve earned the right to share this research without risk to my career.”

November 2015

Included in the PDF of a lecture Pielke Jr. gave at the Dutch Association of Science Journalists, under the category of “questions NOT addressed in this talk” he wrote:14Roger A. Pielke, Jr. “You Can’t Say That! Journalism, Science and Politics” (PDF), CIRES. PDF retrieved from Google Drive. Archived .pdf on file at DeSmog.

“Is human-caused climate change real and/or significant? –

– Me: Yes it is

What policies make sense in response?

– Me: Read my book! [The Climate Fix]”

In his summary, Pielke says that extreme weather cannot be equated with climate change:

“Have disasters become more costly because of human-caused climate change? Only one answer to this question is strongly supported by the available data, the broad scientific literature and the assessments of the IPCC:

No.

There is exceedingly little evidence to support claims that disasters have become more costly because of human caused climate change.”

July 2013

In testimony before the U.S. Senate Committee on Environment & Public Works, Pielke Jr. declared:15“STATEMENT OF DR. ROGER PIELKE, JR. to the COMMITTEE ON ENVIRONMENT AND PUBLIC WORKS of the UNITED STATES SENATE HEARING on CLIMATE CHANGE: IT’S HAPPENING NOW 18 July 2013” (PDF), July 19, 2013. Reprinted by Science &  Public Policy Institute. Archived .pdf on file at DeSmog.

“It is misleading, and just plain incorrect, to claim that disasters associated with hurricanes, tornadoes, floods or droughts have increased on climate timescales either in the United States or globally. It is further incorrect to associate the increasing costs of disasters with the emission of greenhouse gases.”

However, in clarification, he adds that he does believe climate change is caused by man’s activity:16“STATEMENT OF DR. ROGER PIELKE, JR. to the COMMITTEE ON ENVIRONMENT AND PUBLIC WORKS of the UNITED STATES SENATE HEARING on CLIMATE CHANGE: IT’S HAPPENING NOW 18 July 2013” (PDF), July 19, 2013.

 “Humans influence the climate system in profound ways, including through the emission of carbon dioxide via the combustion of fossil fuels […] It does mean however that some activists, politicians, journalists, corporate and government agency representatives and even scientists who should know better have made claims that are unsupportable based on evidence and research.”

January 6, 2005

Roger Pielke and co-author Daniel Sarewitz write in The New Republic Online:17Daniel Sarewitz & Roger A. Pielke, Jr. “Rising Tide” (PDF), The NewRepublic Online, January 6, 2005. Archived .pdf on file at DeSmog.

“Global climate change is real, and developing alternative energy sources and reducing global carbon-dioxide emission is essential. But the claim that action to slow climate change is justified by the rising toll of natural disasters–and, by extension, that reducing emissions can help stanch these rising losses–is both scientifically and morally insupportable.”

Co-writing with Christopher Green in the Rocky Mountain News, Pielke Jr. writes why he disagrees with cap-and-trade:20Roger Pielke Jr. and Christopher Green. “Obama plan a good start to climate policy” (PDF) Rocky Mountain News, November 22, 2008. Archived .pdf on file at DeSmog.

“The Obama plan for climate policy involves one very good idea – investment in new technologies and infrastructure – and one very bad one: cap-and-trade.

To understand why cap-and-trade is a bad idea, we need only to look to lessons from Europe’s experiences.”

Roger Pielke and co-author Daniel Sarewitz write in the opinion section of the Las Angeles Times:

“Efforts to slow global warming will have no discernible effect on hurricanes for the foreseeable future.

Writing in Rocky Mountain News, Roger Pielke discusses “pre-emptive” policies to combat climate change:22Roger A. Pielke Jr. “Speakout: Pre-emptive politics ignore science” (PDF), Rocky Mountain News, August 18, 2003. Retrieved from Centre for Science & Policy Research at the University of Colorado. Archived .pdf on file at DeSmog.

“We risk bad policy when all choices before us are bad ones. For instance, the Kyoto protocol on climate change has its supporters and opponents, but very few are willing to admit that debate over its implementation has considerably more symbolic value than practical effect. The debate over the war on Iraq may have been similarly misguided as better policy options may have been ignored. In both cases, a commitment to pre-emption enables the politicization of intelligence, which then serves as a constraint on options that may be more effective but, for certain ideologues, politically less desirable.

Pre-emption hurts the policy process when it results in a dearth of choice.”

February 23, 2003

Writing in the opinion section of Newsday.com, Roger Pielke Jr. outlines his view on the Kyoto protocol:23Roger A. Pielke JR. “When Science Gets Political,Newsday.com, February 23, 2003. Retrieved from Centre for Science & Policy Research at the University of Colorado. Archived .pdf on file at DeSmog.

“Today we see a subset of scientists trying to use their science to affect political outcomes. The most obvious example is with the Kyoto protocol on global warming, where scientists are arrayed on both sides of the debate. What policy makers need from scientists is not support for or against the protocol, but practical alternatives to deal with climate change. The protocol is more a symbol than an proposal for a real solution.”

Writing in the Albuquerque Journal, in an article titled “Climate Changes; Society has to learn to adapt,” Daniel Sarewitz and Roger Pielke Jr. declare:24Daniel Sarewitz and Roger Pielke JR. “Climate Changes; Society Has To Learn To Adapt,” The Albuquerque Journal, August 5, 2001.

“Of course, it is quite reasonable to believe, as many climate scientists do, that the record of past temperature increased, combined with knowledge of atmospheric chemistry and physics, foretells a warmer future. But what such scientists do not, and cannot, know is this: what will be the impact of such warming on humans and the environment,and how will those impacts change if we limit emissions?”

According to the authors, “climate policy makers continue to focus on energy policy as the primary means to address future climate impacts. The approach is simply doomed to fail. Why has the idea of adaptation been so neglected in the political and scientific arenas?”

“Predictions of the future can be more dangerous than ignorance, if they induce us to behave in ways that reduce our resilience in the face of inevitable uncertainties and contingencies.

In fact we are in an era of good fortune when it comes to extreme weather. This is a topic I’ve studied and published on as much as anyone over two decades. My conclusion might be wrong, but I think I’ve earned the right to share this research without risk to my career.”

Pielke says that he earned the term “denier” after questioning an IPCC report graph. He adds, “I was right to question the IPCC’s 2007 report, which included a graph purporting to show that disaster costs were rising due to global temperature increases.”67Marc Morano. “Extreme Weather expert Dr. Roger Pielke Jr.: ‘My Unhappy Life as a Climate Heretic’,” Climate Depot, December 3, 2016.

He emphasizes his point that “There is not a strong basis for connecting weather disasters with human-caused climate change,” noting that “The IPCC never acknowledged the snafu, but subsequent reports got the science right.”68Marc Morano. “Extreme Weather expert Dr. Roger Pielke Jr.: ‘My Unhappy Life as a Climate Heretic’,” Climate Depot, December 3, 2016.

When Arizona Rep. Raul Grijalva, the ranking Democrat on the House Natural Resources Committee investigated Pielke for what he described as “serious misstatements by Prof. Pielke of the scientific consensus on climate change,” Piekle said that this significantly damaged his reputation and was why he decided to pursue other subjects than climate change. He concludes:

“Academics and the media in particular should support viewpoint diversity instead of serving as the handmaidens of political expediency by trying to exclude voices or damage reputations and careers. If academics and the media won’t support open debate, who will?”69Marc Morano. “Extreme Weather expert Dr. Roger Pielke Jr.: ‘My Unhappy Life as a Climate Heretic’,” Climate Depot, December 3, 2016.

Archived .pdf on file at DeSmog.

Pielke writes in the paper that its objective is to present a “straightforward approach to tracking international (and national) progress with respect to implementation of the Paris Agreement” and is designed for “observers who may not be insiders to better understand climate policy.”

According to Pielke, in order to successfully reach emissions reductions targets, the world would have to “deploy about 190 x 1.5 gigawatt power plants worth of carbon-free energy every year from now until 2100.”

“The proportion of global energy consumption from carbon-free sources provides a readily understandable and easily tracked metric with respect to progress in the implementation of the Paris Agreement on climate change. Today, that percentage is less than 14%. By the end of the century, it needs to be greater than 90% if the ultimate objective of the FCCC is to be achieved,” Pielke Jr. writes.

Roger Pielke Jr.  gave a keynote lecture to the VWN – de Vereniging voor Wetenschapsjournalistiek en -communicatie, the Dutch Association of Science Journalists. According to the PDF version of his talk, Pielke covered extreme weather events, mentioning a study he co-wrote in 1998 with Chirs Landsea. He criticizes the IPCC for reliance on “one study” on extreme weather in 2007 while establishing a link between extreme weather and global warming. The later portions of his talk are devoted to his label as “climate change denialist” and equates this with having lost his job.72Roger A. Pielke, Jr. “You Can’t Say That! Journalism, Science and Politics” (PDF), CIRES. PDF retrieved from Google Drive. Archived .pdf on file at DeSmog.

In summary, Pielke says that extreme weather cannot be equated with climate change:

“Have disasters become more costly because of human-caused climate change? Only one answer to this question is strongly supported by the available data, the broad scientific literature and the assessments of the IPCC:

No.

There is exceedingly little evidence to support claims that disasters have become more costly because of human caused climate change.”

In his letter to University of Colorado President Bruce Benson, Grijalva requested that the university disclose all of Pielke’s sources for external funding. The letter points out controversy of climate research by Dr. Willie Soon, and notes that his lack of disclosure “may not be isolated incidents.”75“Dear President Benson:” (PDF), Congress of the United States, February 24, 2015.

“Prof . Roger Pielke, Jr., at CU‘s Center for Science and Technology Policy Research has testified numerous times before the U.S .

Writing at the blog FiveThirtyEight, Roger Pielke Jr. contends that while natural disasters are costing more money, it is not due to climate change.76Roger Pielke Jr. “Disasters Cost More Than Ever — But Not Because of Climate Change,” FiveThirtyEight, March 19, 2014. Archived January 25, 2017. Archive.is URL: https://archive.is/qU5u8

“When you read that the cost of disasters is increasing, it’s tempting to think that it must be because more storms are happening. They’re not. All the apocalyptic ‘climate porn’ in your Facebook feed is solely a function of perception. In reality, the numbers reflect more damage from catastrophes because the world is getting wealthier. We’re seeing ever-larger losses simply because we have more to lose — when an earthquake or flood occurs, more stuff gets damaged. And no matter what President Obama and British Prime Minister David Cameron say, recent costly disasters are not part of a trend driven by climate change. The data available so far strongly shows they’re just evidence of human vulnerability in the face of periodic extremes,” Pielke Jr. writes.

Top climatologists responded to Pielke’s article, concluding that Nate Silver‘s FiveThirtyEight had “used flawed data to make its conclusions,” reported ThinkProgress.77Emily Atkin. “First Climate Article On Nate Silver’s Data Website Uses ‘Deeply Misleading’ Data, Top Climatologists Say,” ThinkProgress, March 19, 2014. Archived January 25, 2017. Archive.is URL: https://archive.is/xctux

Pielke’s piece is deeply misleading, confirming some of my worst fears that Nate Silver’s new venture may become yet another outlet for misinformation when it comes to the issue of human-caused climate change,” said Michael Mann, director of the Earth System Science Center at Pennsylvania State University. “Pielke uses a very misleading normalization procedure that likely serves to remove the very climate change-related damage signal that he claims to not be able to find.”

Two climate scientists, Michael Mann and Kevin Trenberth, later said the Pielke Jr. had sent them emails threatening possible legal action in response to their criticism of his findings, reported Huffington Post. Pielke responded that it was “ridiculous” to characterize his emails as threats against Michael Mann, however apologized to both scientists.78Michael Calderone. “FiveThirtyEight Apologizes On Behalf Of Controversial Climate Science Writer,” The Huffington Post, March 28, 2014. Archived January 26, 2017. Archive.is URL: https://archive.is/YrfDK

In an email to Huffington Post, Mann said Pielke sent him “a threatening email in response to my fair criticism of his piece.” Mann added that a representative from FiveThirtyEight later contacted him and offered “an apology for what they characterized as unacceptable behavior by Pielke.”79Michael Calderone. “FiveThirtyEight Apologizes On Behalf Of Controversial Climate Science Writer,” The Huffington Post, March 28, 2014. Archived January 26, 2017. Archive.is URL: https://archive.is/YrfDK

Trenberth said that he considered the email he received from Pielke as “a threat to me,” telling Huffington Post “He was very accusatory and threatened me if I did not respond.” Trenberth forwarded some of the email’s text to Huffington Post:80Michael Calderone. “FiveThirtyEight Apologizes On Behalf Of Controversial Climate Science Writer,” The Huffington Post, March 28, 2014.

Once again, I am formally asking you for a public correction and apology,” Pielke wrote to Trenberth. “If that is not forthcoming I will be pursuing this further. More generally, in the future how about we agree to disagree over scientific topics like gentlemen?”

FiveThirtyEight itself published a debunking of Pielke’s piece in March, 2014, written by an MIT Climate Scientist Kerry Emanuel.81Kerry Emanuel. “MIT Climate Scientist Responds on Disaster Costs And Climate Change,” FiveThirtyEight, March 31, 2014. Archived January 27, 2014. Archive.is URL: https://archive.is/anFxo

SkepticalScience also critiqued Pielke Jr.’s original blog piece, noting that Pielke only chose to examine economic losses from global disasters from 1990 to 2013 while Munich Re offers data82Cherry picked and misrepresented climate science undermines FiveThirtyEight brand,” Skeptical Science, March 24, 2014.

The Center for Research on the Epidemiology of Disasters also has natural disaster cost estimates ranging back to the year 1900. Skeptical Science notes that “Pielke has dismissed climate change as a causal factor using data from just 1990,” pointing out the irony in that Pielke himself had criticized Munich Re for using data only going back to 1980:84Dale S. Rice. “Report: Climate change behind rise in weather disasters,USA Today, October 10, 2012. Archived January 25, 2017. Archive.is URL: https://archive.is/UMflB

“Thirty years is not an appropriate length of time for a climate analysis, much less finding causal factors like climate change,” Pielke Jr. said.

SkepticalScience found that the positive trend in global disaster losses in the Munich Re data was almost 30 percent larger for 1980–2013 than was for 1990–2013.  “What’s more, the trend in disaster losses for 1980–2013 is statistically significant at the 99 percent confidence level, whereas the trend for the 1990–2013 window cherry picked by Pielke is not statistically significant,” they wrote.85Cherry picked and misrepresented climate science undermines FiveThirtyEight brand,” Skeptical Science, March 24, 2014.

Pielke Jr. wrote a follow post at FiveThirtyEight, noting that “Human-caused climate change is both real and important, so being careful about what claims science can support and which it can’t is imperative.” According to SkepticalScience , Pielke “dug himself even deeper into a hole by claiming that efforts and technologies to mitigate disaster damages don’t make a difference in damage trends ‘for floods, U.S. hurricanes or tornadoes.’  The problem is that those referenced papers he links don’t support his claims. ”86Roger Pielke Jr. “Following Up on Disasters And Climate Change,” FiveThirtyEight, March 21, 2014.

July 18, 2013

Roger Pielke Jr. testified before the U.S. Senate Committee on Environment & Public Works at a hearing on climate change. In his full testimony (PDF), reprinted by the Science and Public Policy Institute (SPPI), Pielke declares, as some “take-home points” that:93“STATEMENT OF DR. ROGER PIELKE, JR. to the COMMITTEE ON ENVIRONMENT AND PUBLIC WORKS of the UNITED STATES SENATE HEARING on CLIMATE CHANGE: IT’S HAPPENING NOW 18 July 2013” (PDF), July 19, 2013.

“It is misleading, and just plain incorrect, to claim that disasters associated with hurricanes, tornadoes, floods or droughts have increased on climate timescales either in the United States or globally. It is further incorrect to associate the increasing costs of disasters with the emission of greenhouse gases.”

According to Pielke Jr., other “take-home points” include that weather-related losses have not increased since 1990, hurricanes have not increased in intensity since 1900, floods have not increased since 1950, tornadoes have not increased since 1950, and drought has become shorter and less frequent over the last century.94“STATEMENT OF DR.

 “Humans influence the climate system in profound ways, including through the emission of carbon dioxide via the combustion of fossil fuels […] It does mean however that some activists, politicians, journalists, corporate and government agency representatives and even scientists who should know better have made claims that are unsupportable based on evidence and research.”

Writing about the testimony on his blog, Pielke Jr. says that he is “declaring victory in this debate” while any future claims associating floods, drought, hurricanes and tornadoes with human-caused climate change would be “Zombie science.”96Coverage of Extreme Events in the IPCC AR5,” Roger Pielke Jr.’s Blog, October 3, 2013.

Holdren noted that Senator Jeff Sessions had quoted both Roger Pielke Jr. and Roy Spencer in February 2014 testimony, to which Holdren had replied that “the indicated comments by Dr. Pielke, and similar ones attributed by Senator Sessions to Dr. Roy Spencer of the University of Alabama, were not representative of mainstream views on this topic in the climate-science community.” Holdren said his comments were following through on his promise to “record a more complete response with relevant scientific references.”99“Drought and Global Climate Change: An Analysis of Statements by Roger Pielke Jr” (PDF), John P.

ThinkProgress also outlined an interchange between Pielke and Holdren on Twitter that happened in December of 2014. Pielke had criticized Holdren for staying “safe” on climate:

“In a nutshell, Holdren’s response is sloppy and reflects extremely poorly on him. Far from showing that I am outside the scientific mainstream, Holdren’s follow-up casts doubt on whether he has even read my Senate testimony,” Pielke claims. He concludes that Holdren “has gone too far” by supposedly attempting to “delegitimize a colleague.”

October 2010

Roger Pielke Jr. is the author of The Climate Fix: What Scientists and Politicians Won’t Tell You About Global Warming. The book, according to one review, “wants everyone to take a giant step backward and restart the entire conversation” on climate change science. While “Pielke agrees with the rest of his field on the need to stop emitting carbon dioxide and to stabilize its concentration in the atmosphere at somewhere between 350 and 500 parts per million; he just doesn’t want scientists to tell the rest of us how to get there.” He instead focuses on the uncertainties of climate science and the politicization of the debate.103Dave Levitan. “Book Review: The Climate Fix: What Scientists and Politicians Won’t Tell You About Global Warming,” IEEE Spectrum, January 3, 2011.

“Conventional wisdom on how to deal with climate change has failed us, according to Roger Pielke, and it’s time to change course.

In this thought-provoking discussion of the interaction between science and politics, Pielke proposes a means for digging ourselves out of this climate change mess we’ve created.”

July 2000

Writing in The Atlantic Monthly with co-author Daniel Sarewitz, Roger Pielke Jr. and Sarewitz claim that the recent Hurricane Mitch may have been a “public relations gift to environmentalists” and claim that “disasters like Mitch are a present and historical reality, and they will become more common and more deadly regardless of global warming.”105Daniel Sarewitz and Roger Pielke Jr. “Breaking the Global-Warming Gridlock” (PDF), The Atlantic Monthly, July 2000. Retrieved from Centre for Science & Policy Research at the University of Colorado. Archived .pdf on file at DeSmog.

Discussing modern environmentalists, the authors claim they are “in the habit of calling on science to help advance their agenda.” They say that, in light of global warming, the call to reduce carbon dioxide emissions was “used to rationalize the moral imperative, unify the environmentalist agenda, and determine the political solution.”106Daniel Sarewitz and Roger Pielke Jr. “Breaking the Global-Warming Gridlock” (PDF), The Atlantic Monthly, July 2000. Retrieved from Centre for Science & Policy Research at the University of Colorado. Archived .pdf on file at DeSmog.

The authors go on to criticize the Intergovernmental Panel on Climate Change’s (IPCC) reliance on climate models. “Although various models can reproduce past temperature records, and yield similar predictions of future temperatures, they are unable to replicate other observed aspects of climate.” The authors write that “it is simply not possible to know far in advance if the models agree on future temperature because they are similarly right or similarly wrong.”107Daniel Sarewitz and Roger Pielke Jr. “Breaking the Global-Warming Gridlock” (PDF), The Atlantic Monthly, July 2000. Retrieved from Centre for Science & Policy Research at the University of Colorado. Archived .pdf on file at DeSmog.

Talking about sea level rise, authors say that while “Sea-level rise is a problem […] anthropogenic global warming is not the only culprit, and reducing emissions cannot be the only solution.” They add that “Predicting the impact on climate of reducing carbon dioxide emissions is so uncertain as to be meaningless.”108Daniel Sarewitz and Roger Pielke Jr. “Breaking the Global-Warming Gridlock” (PDF), The Atlantic Monthly, July 2000. Retrieved from Centre for Science & Policy Research at the University of Colorado. Archived .pdf on file at DeSmog.

Authors also put an emphasis on adaptation to climate change, which they say has been “taboo in many circles.”109Daniel Sarewitz and Roger Pielke Jr. “Breaking the Global-Warming Gridlock” (PDF), The Atlantic Monthly, July 2000.

“Reframing the climate problem could mobilize this constituency [those subject to the effects of the weather] and revitalize the Framework Convention. The revitalization could concentrate on coordinating disaster relief, debt relief, and development assistance, and on generating and providing information on climate that participating countries could use in order to reduce the vulnerability.”

Pielke Jr. and Sarewitz claim that, while “[E]fforts to reduce carbon dioxide emissions need not be abandoned […] An opportunity to advance the cause of adaptation is on the horizon.” They contend that the United nation’s Frameworkk Convention on Climate Chnage should instead focus on “promoting the diffusion of energy-efficient technologies that would reduce emissions” and that this should be “promoted independently” from emissions regulations.110Daniel Sarewitz and Roger Pielke Jr. “Breaking the Global-Warming Gridlock” (PDF), The Atlantic Monthly, July 2000.

“Understanding the strengths and limits of predictions is important because our sense of certainty about events in the future influences the actions we take today,”  Pielke Jr. and Sarewitz write. “For example, predictions of global warming have focused international environmental efforts on reducing greenhouse gas emissions. But future economic trends, geopolitical events, and technological advances — three variables that defy predictive accuracy — will have a much greater impact on emissions than any conceivable international agreements.”
