Stance on Climate Change

“There has been a stunning disconnect involving land temperatures globally and CO2, whether man-made or naturally sourced. The oceans continue to warm, while the surface record flatlines. […] It is obvious that the surface records are NOT going up – they are basically in a 0.2C flatline […]”3The Recent Temperature and CO2 Disconnect,” The Colder Side of Global Warming. Accessed May 7, 2012.

Key Quotes

“If CO2 is to be considered a major driver of temperatures, it is doing a counterintuitive dance around the numbers.”4The Recent Temperature and CO2 Disconnect,” The Colder Side of Global Warming. Accessed May 7, 2012.

Wysmuller signed the “Realist Catholic Climate Declaration,” drafted by Heartland Institute policy analyst William Briggs, which stated, “the earth’s climate has always changed, is changing now, and will never cease changing. The extent to which man is responsible for climate change is not known, only surmised. There is no earthly force capable of stopping climate change,” and that, “the salvation of souls is of more pressing concern than the air temperature. Pray to God and pray for your neighbor, not to the planet.”6The Declaration,” Realist Catholic Climate Declaration, Archived October 29, 2020.

The declaration was endorsed by Anthony Watts’ blog Watts Up With That, in a post by Charles Rotter, which stated, “please share this as widely as possible. With the concept of ‘eco-sins’ being bruited, and the return of paganism, this declaration is timely and important.”8 Charles Rotter,“Realist Catholic Climate Change Declaration,” Watts Up with That, October 13, 2019.

Wysmuller appeared at a climate change denial symposium staged in the German parliament by the far right AfD (Alternative für Deutschland) party. Other featured speakers at the event included Christopher Monckton, Gernot Patzelt, and Henrik Svensmark.10 Kate Connolly. “Germany’s AfD turns on Greta Thunberg as it embraces climate denial,” The Guardian, May 14, 2019.

The European Institute for Climate and Energy (EIKE) promoted the event on its website to “set facts against CO2 hysteria and climate activism.”11 Von Edgar L. Gärtner. “14.

Germany’s AfD accelerated its promotion of climate change denial since the emergence of Swedish activist Greta Thunberg in August 2018. A smear campaign against Thunberg mocked her autism as a form of “psychosis” and compared her to a cult leader and a member of a Nazi youth organization. AfD attributed Thunberg’s popularity to the work of “PRprofessionals seeking to bedevil the plant-nutrient carbon dioxide.”12 Kate Connolly. “Germany’s AfD turns on Greta Thunberg as it embraces climate denial,” The Guardian, May 14, 2019.

Speaking to the Guardian, a representative of Greenpeace Germany said of the event:

“The AfD is using the Bundestag as a stage for its dissemination of climate lies. They invite fake experts to a so-called symposium on climate change to generate content for mass dissemination via social media channels and stir up hatred and anger on the internet. We are experiencing a shift to the right on social media and in society. In a short period of time, the new right has established its own counter-society on climate issues. With troll armies, agitating magazines and the support of climate skeptics like EIKE, it has created its own sphere that is massively underestimated.”14 Kate Connolly. “Germany’s AfD turns on Greta Thunberg as it embraces climate denial,” The Guardian, May 14, 2019.

In January 2018, more than 200 scientists endorsed an open letter calling on the American Museum of Natural History (AMNH) to remove climate change denier Rebekah Mercer from its board and to “end ties to anti-science propagandists and funders of climate science misinformation.” The New York Times reported that those among the AMNH letter calling for Mercer to step down were Michael E. Mann, director of the Earth System Science Center at Pennsylvania State University, and Katharine Hayhoe, director of the Climate Science Center at Texas Tech University.16 Robin Pogrebin and Somini Sengupta. “A Science Denier at the Natural History Museum? Scientists Rebel,” The New York Times, January 25, 2018. Archived February 13, 2018. URL:

Wysmuller was among a group of climate change deniers who responded with their own open letter, calling for the AMNH “not to cave in to this pressure.” The letter was signed by numerous individuals with ties to groups funded by the Mercer Family Foundation such as Will Happer of the CO2 CoalitionRichard Lindzen, a fellow at the Cato InstituteCraig Idso, the chairman of the Center for the Study of Carbon Dioxide and Global Change. There are a number of signatories affiliated with the Heartland Institute, which has received over $5.78 million from the Mercer Family Foundation since 2008.17 Graham Readfearn. “Climate Science Deniers Defend New York’s American Museum of Natural History From Calls to Drop Trustee Rebekah Mercer,” DeSmog, February 6, 2018.

The letter reads:18 mnh18-feb4-petitionletter (PDF – Untitled). Retrieved from Watts Up With That.

“The Earth has supported abundant life many times in the geological past when there were much higher levels of carbon dioxide in the atmosphere. It is quite likely that future generations will benefit from the enrichment of Earth’s atmosphere with more carbon dioxide.

“Make no mistake, the agitators are not defending science from quackery — quite the contrary!”

Thomas Wysmuller was a presenter at the “4th World Conference on Climate Change” in Rome.19 Past Conferences Photo Gallery, Archived January 4, 2018. URL:

A DeSmog investigation of the conference found that the event had been hijacked by climate science deniers who had previously called for climate scientists to be investigated for fraud. The conference was organized by ConferenceSeries, also known as OMICS, which promotes hundreds of meetings around the world.20Exclusive: UN, EU Agencies Reject Ties to Conference Hijacked by Climate Science Deniers,” DeSmog, May 31, 2017.

The U.S. government’s Federal Trade Commission launched a court action against the group in August 2016 that alleged deceptive marketing practices. Nils-Axel Morner is listed as one of the Chairs/Co-chairs of the conference, and also helped organize another climate change denial conference in London in September 2016.21Climate Change 2017 Report,” Archived January 4, 2018. URL: 22FTC Charges Academic Journal Publisher OMICS Group Deceived Researchers,” Federal Trade Commission, August 26, 2016. Archived January 4, 2018. URL:

After being contacted by DeSmog, several presenters said that their names “should not be on the program” of the conference in Italy. OMICS, who was also contacted, said it would “investigate” the line-up for its conference and if it found “unnecessary science,” it would contact attendees to inform them “about the real faces of those who are looking to make a platform for spreading the nonsense through our forum.”23 Past Conferences Photo Gallery, Archived January 4, 2018.

On the conference program, Wysmuller was listed as affiliated with “NASA TRCS Climate Group,” which DeSmog‘s Graham Readfearn noted “ could be easily mistaken as a legitimate group at the U.S. space agency,” but rather is a group of retired NASA employees who deny the existence of man-made climate change.24 Past Conferences Photo Gallery, Archived January 4, 2018.

Wysmuller was a signatory of a petition (PDF) organized by Richard Lindzen of the Cato Institute urging President Donald Trump to pull the United States out of the United Nations international convention on climate change (UNFCCC).25 “PETITION” (PDF), February 23, 2017. Richard Lindzen. PDF Archived at DeSmog.

DeSmog investigated the list, and found that only a small handful of the signatories could be considered “even remotely ‘qualified’ or ‘eminent’ — but not in the field of climate science.” The list included individuals “interested in climate,” and one signatory who only identified as an “emailer who wished to sign the petition” while some signers provided no affiliation or address whatsoever.27 Graham Readfearn. “Climate Science Denier Richard Lindzen’s List of 300 “Scientists” Sent to Trump Is the Usual Parade of Non-Experts,” DeSmog, February 27, 2017.

Thomas Wysmuller was a signatory to a Cornwall Alliance open letter supporting Scott Pruitt for EPA Administrator under the Trump administration.28Open Letter Supporting Scott Pruitt for EPA Administrator,” Cornwall Alliance, January 5, 2017. Archived January 19, 2017. URL:

“Mr. Pruitt has also demonstrated understanding of and open-mindedness toward scientific insights crucial to the formulation and implementation of environmental regulation. He is prepared to hear all sides in debates over the risks and benefits of various activities that come under the purview of the EPA,” reads the letter.

On January 12, 2017, Senate Democrats raised conflict of interest concerns regarding Scott Prutt’s fossil fuel ties. Pruitt had spent years working to combat the Obama Administration’s Clean Power Plan.29 Ben Jervey. “Mapping EPA Nominee Scott Pruitt’s Many Fossil Fuel Ties,” DeSmog, January 13, 2017.

In an open letter to the Office of Government Ethics, members of the Senate’s environmental panel commented:

“During his tenure as Attorney General of Oklahoma, Mr. Pruitt has blurred the distinction between official and political actions, often at the behest of corporations he will regulate if confirmed to lead EPA,” the letter said. “Public reporting based on documents produced by Freedom of Information Act requests illustrate how Mr. Pruitt and members of his staff have worked closely with fossil fuel lobbyists to craft his office’s official positions.”

Pruitt was further grilled on his fossil fuel ties at his confirmation hearing on January 18.30 Ben Jervey and Steve Horn. “EPA Nominee Scott Pruitt Gets Grilled on Fossil Fuel Ties at Confirmation Hearing,” DeSmog, January 18, 2017.

On March 15, 2013, Thomas Wysmuller, alongside Walter Cunningham, Harold Doiron, and Heartland President Joseph Bast spoke at a panel discussion where they explain “why they are urging government agencies to cease their ‘unbridled advocacy’ of Anthropogenic Global Warming & Return Integrity to the Scientific Method.”34 Jim Lakely. “Apollo 7 Astronaut Walter Cunningham to Headline ‘Right Climate Stuff’ Event at CPAC 2013,” The Heartland Institute, March 8, 2013.

In January 2013, TRCS issued a summary of its findings as follows (according to a press release issued by The Heartland Institute):

  1. The science that predicts the extent of anthropogenic global warming is not settled science.
  2. There is no convincing physical evidence of catastrophic anthropogenic global warming.
  3. Computer models need to be validated before being used in critical decision-making.
  4. Because there is no immediate threat of global warming requiring swift corrective action, we have time to study global climate changes and improve our prediction accuracy.
  5. The U.S. government is over-reacting to concerns about anthropogenic global warming.
  6. A wider range of solution options should be studied for global warming or cooling threats from any credible cause.

May 21–23, 2012

Wysmuller was a speaker at the Heartland Institute’s Seventh International Conference on Climate Change (ICCC7). A Heartland press release implies that he was a “Former NASA scientist,” although according to his website, his highest position was as an intern.35Former NASA Scientists, Astronauts to Attend Heartland Institute Climate Conference, May 21 – 23 in Chicago,” PRWeb, April 19, 2012. He spoke on the Nasa Letter Writers Panel, along with Harrison Schmitt, Harold Doiron, Walter Cunningham, and Leighton Steward. Video footage can be viewed below.

DeSmogBlog researched the co-sponsors behind Heartland’s ICCC7 and found that they had collectively received over $67 million from ExxonMobil, the Koch Brothers and the conservative Scaife family foundations.

March 28, 2012

Wysmuller was one of 49 former “NASA scientists” to sign an open letter to NASA and the Goddard Institute for Space Studies (GISS) to cease they describe as “unbridled advocacy of CO2 being the major cause of climate change.”36 Gus Lubin. “49 Former NASA Scientists Send A Letter Disputing Climate Change,” Business Insider, April 11, 2012.

“We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated,” the letter stated.
