Thomas Wysmuller

Thomas Wysmuller


B.A. with a dual major in sociology and political science, and a concentration in meteorology at NYU. [1]


Thomas Wysmuller is the owner of which he describes as part of the “Public Policy industry.” He gives regular speeches on “The Colder Side of Global Warming.”

Wysmuller has worked as a meteorologist for the Royal Dutch Weather Bureau in Amsterdam and was an intern at NASA. [2]

Wysmuller gives regular lectures on Global Warming to universities, high schools, and public/private organizations.

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 …” [3]

Key Quotes

“If CO2 is to be considered a major driver of temperatures, it is doing a counterintuitive dance around the numbers.” [3]

Key Deeds

January 5, 2017

Thomas Wysmuller was a signatory to a Cornwall Alliance open letter supporting Scott Pruitt for EPA Administrator under the Trump administration. [13]

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. [14]

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[15]

Some notable signatories of the Cornwall Alliance letter, as of January 5, 2017, included:

June 11-12, 2015

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. [11]

July 7 - 9, 2014

Thomas Wysmuller was a speaker at the Heartland Institute’s Ninth International Conference on Climate Change (ICCC9) in Las Vegas, Nevada. [9]

March, 2013

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.” [10]

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. [4]

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.” [5]

“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.

SkepticalScience published a critique of the letter which was republished in The Guardian. [6], [7]
