Background

John Francis Clauser is an experimental physicist and member of the board of directors⁴“Nobel Laureate Joins CO2 Coalition, Challenges ‘Green’ Narrative,” CO2 Coalition (undated). Retrieved from Contact Contact May 8, 2023. of the CO2 Coalition, a group that claims that both CO2 emissions and associated global warming would be “of great benefit to life on earth.”⁵“CO2 Fundamentals,” CO2 Coalition. Archived February 15, 2017. Archive.is URL: https://archive.is/WNNlH

Clauser has declared “there is no real climate crisis.”⁶“Nobel Laureate John Clauser Elected to CO2 Coalition Board of Directors,” CO2 Coalition, May 5, 2023. Archived May 5, 2023. Archive URL: https://archive.ph/el0v4

He was one of three physicists to share the Nobel Prize in Physics in 2022 “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.” ⁷“John Clauser – Facts – 2022,” NobelPrize.org.

According to his biography at the American Institute of Physics, “John Clauser is an experimental physicist who researches interferometry and quantum theory. He won the Wolf Foundation Prize in Physics in 2010. His institutional affiliations include Lawrence Livermore National Laboratory and University of California at Berkeley.”⁸“JOHN F. CLAUSER,” AIP.

Clauser is also an “avid sailboat racer,” and sails in the Berkeley Yacht Club and Richmond Yacht Club.⁹Monica Grant. “Bay Area Sailor John Clauser Wins Nobel Prize,” Latitude 38, October 5, 2022. Archived May 8, 2023. Archive URL: https://archive.ph/wJb9c

Stance on Climate Change

May 5, 2023

The CO2 Coalition quoted Clauser in its announcement of his joining their board of directors:¹⁰“Nobel Laureate John Clauser Elected to CO2 Coalition Board of Directors,” CO2 Coalition, May 5, 2023. Archived May 5, 2023. Archive URL: https://archive.ph/el0v4

“The popular narrative about climate change reflects a dangerous corruption of science that threatens the world’s economy and the well-being of billions of people. Misguided climate science has metastasized into massive shock-journalistic pseudoscience. In turn, the pseudoscience has become a scapegoat for a wide variety of other unrelated ills. It has been promoted and extended by similarly misguided business marketing agents, politicians, journalists, government agencies, and environmentalists. In my opinion, there is no real climate crisis. There is, however, a very real problem with providing a decent standard of living to the world’s large population and an associated energy crisis. The latter is being unnecessarily exacerbated by what, in my opinion, is incorrect climate science.”

Clauser spoke at a press conference hosted by the Deposit of Faith Coalition,¹²Maxine Joselow. “He won a Nobel Prize. Then he started denying climate change,” The Washington Post, November 16, 2023. Archived November 22, 2023. Archive URL: https://archive.ph/UNWgr a group that declares “those pushing the anti-God and anti-family climate agenda need to be called out and exposed.”¹³“Deposit of Faith Coalition,” Church Militant.

It adds on its website, “The Religious Left has become an invaluable ally to the global cabal, to the World Economic Forum, the United Nations and the World Health Organization, in pushing the man-made climate change narrative.”¹⁴“Deposit of Faith Coalition,” Church Militant.

“Much as it may upset many people, my message is the planet is not in peril,” Clauser said during his speech. “I call myself a climate denier,” he added. “I’ve been told that’s not politically correct. So I guess I’m a climate crisis d-word person.”¹⁵Maxine Joselow. “He won a Nobel Prize. Then he started denying climate change,” The Washington Post, November 16, 2023. Archived November 22, 2023. Archive URL: https://archive.ph/UNWgr

He also claimed that he had privately met with President Joe Biden when 2022 Nobel Prize winners were invited to the White House, however The Washington Post was unable to confirm this account. Other speakers at the event included Marc Morano, Alex Newman, and Michael Voris.¹⁶Maxine Joselow. “He won a Nobel Prize.

University of Pennsylvania Climate Scientist Michael Mann described Clauser’s arguments as “pure garbage” and “pseudoscience,” according to The Washington Post, referring to Clauser’s assertions that Earth’s temperature is primarily determined by cloud cover, not carbon dioxide emissions from burning fossil fuels.¹⁷Maxine Joselow. “He won a Nobel Prize.

In an interview with the Epoch Times, Clauser suggested increase in atmospheric carbon dioxide “may or may not be made by human beings.” He claimed, “It doesn’t really matter where it comes from.”¹⁸Nathan Worcester. “EXCLUSIVE: ‘We Are Totally Awash in Pseudoscience’: Nobel Prize-Winning Physicist on Climate Agenda,” The Epoch Times, August 1, 2023. Archived March 25, 2024. Archive URL: https://archive.ph/ZKp6F

This was one of several claims debunked by Skeptical Science in its 2023 profile of Clauser. “In reality, several lines of evidence have proven the incontrovertible fact that the human combustion of fossil fuels – which today releases nearly 40 billion tons of CO2 per year – is entirely responsible for the 50% increase in Earth’s atmospheric CO2 concentrations since the Industrial Revolution,” Skeptical Science wrote of the claim.¹⁹“John F.

The CO2 Coalition reported Clauser had joined their board of directors.²⁰“Nobel Laureate John Clauser Elected to CO2 Coalition Board of Directors,” CO2 Coalition, May 5, 2023. Archived May 5, 2023. Archive URL: https://archive.ph/el0v4

According to the Coalition’s announcement, Clauser “has criticized the awarding of the 2021 Nobel Prize for work in the development of computer models predicting global warming and told President Biden that he disagreed with his climate policies.”

“Dr. Clauser has developed a climate model that adds a new significant dominant process to existing models,” the announcement claimed.

The announcement notes that “Dr. Clauser’s interest in joining the CO2 Coalition was initiated by CO2 Coalition member Dr. James Enstrom.”
