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 […]” 
“If CO2 is to be considered a major driver of temperatures, it is doing a counterintuitive dance around the numbers.”

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. 
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 Coalition; Richard Lindzen, a fellow at the Cato Institute; and Craig 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. 
“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!”
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. 
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. , 
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.” 
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.

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). 
“In just a few weeks, more than 300 eminent scientists and other qualified individuals from around the world have signed the petition below,” Lindzen wrote in the letter. 
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.

“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. 
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.”

Thomas Wysmuller was a speaker on Panel 13: “The Right Climate Stuff,” at the Heartland Institute’s Tenth International Conference on Climate Change (ICCC10) in Washington, D.C., with Hal Doiron and Walter Cunningham.

Thomas Wysmuller was a speaker at the Heartland Institute’s Ninth International Conference on Climate Change (ICCC9) in Las Vegas, Nevada.  His speech, titled “Tide Gauges/Satellites; Different Measures – Same Ocean! Will the REAL Sea-Level Please Rise???” can be viewed below.
DeSmogBlog has done in-depth research on the other speakers and sponsors from Heartland's ICCC9, which can be found here.
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.” 
- The science that predicts the extent of anthropogenic global warming is not settled science.
- There is no convincing physical evidence of catastrophic anthropogenic global warming.
- Computer models need to be validated before being used in critical decision-making.
- 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.
- The U.S. government is over-reacting to concerns about anthropogenic global warming.
- A wider range of solution options should be studied for global warming or cooling threats from any credible cause.

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.  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.

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.” 
“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.
