John Coleman


John Coleman


According to an article in Columbia Journalism Review, “Coleman had spent half a century in the trenches of TV weathercasting; he had once been an accredited meteorologist, and remained a virtuoso forecaster. But his work was more a highly technical art than a science. His degree, received fifty years earlier at the University of Illinois, was in journalism.” [1]


Coleman is currently employed as the television weatherman for station KUSI in San Diego. Coleman has been a TV weatherman since he was a freshman in college in 1953 and is the founder of the Weather Channel until he was “forced out” a year after the Weather Channel went to air. [2]

A July 2002 article claims that “the relationship between Coleman and Landmark [Coleman's business partner] soured quickly in the face of larger-than-projected losses and, in Batten's view, declining staff morale. The two parted ways just over a year later, but not before airing their dirty laundry in court, Coleman departing the venture entirely.” [3]

Coleman is skeptical of man-made climate change and has aired his views on CNN, Fox News Channel, Showtime and Pen & Teller: B.S. In an interview on Fox News' “Red Eye,” he describes Fox as the “only cable network that will put us on the air.”

Stance on Climate Change

  • “Global Warming, i.e. Climate Change, is not about environmentalism or politics. It is not a religion. It is not something you “believe in.” It is science; the science of meteorology. This is my field of life-long expertise. And I am telling you Global Warming are a nonevent, a manufactured crisis and a total scam. I say this knowing you probably won't believe me, a mere TV weatherman, challenging a Nobel Prize, Academy Award and Emmy Award winning former Vice President of United States. So be it.” [4]
  • “There is no run away climate change. The impact of humans on climate is not catastrophic. Our planet is not in peril.” [5]

Key Quotes

“Some misguided scientists with environmental and political motives manipulated long-term scientific data back in the late 1990's to create an illusion of rapid global warming. Other scientists of the same environmental-extremism type jumped into the circle to support and broaden the 'research' to further enhance the totally slanted, bogus global warming claims.” [4]

“Now the really good news: The increase in our atmospheric carbon dioxide during the 20th and early 21st  centuries has produced no deleterious effects upon Earth’s weather and climate. There is absolutely no correlation between the increase in CO2 and average worldwide or US temperatures. And, predictions of harmful climatic effects due to future increases in hydrocarbon use and resulting increases in minor greenhouse gases such as CO2 do not conform to current experimental knowledge or have any scientific basis. On the other hand, increased carbon dioxide has markedly increased plant growth. Forest growth and farm crop output per acre have grown proportionally with increased atmospheric CO2 that is a key to photosynthesis in plants.” [4]

“Environmental extremist, notable politicians among them then teamed up with movie, media and other liberal, environmentalist journalists to create this wild 'scientific' scenario of the civilization threatening environmental consequences from Global Warming unless we adhere to their radical agenda.” [4]

“Many people don't accept my position that there is no significant man-made global warming because I am simply a Television Meteorologist without a Ph.D.  I understand that…” [6]

Key Deeds

June 11-12, 2015

John Coleman was a speaker on Panel 12: “Effective Climate Science Communication,” at the Heartland Institute’s Tenth International Conference on Climate Change (ICCC10) in Washington, D.C., with Tom Harris and Michael Bastasch. [20]

November 5, 2014

The Heartland Institute's “environmental science and policy experts” published comments following the release of the United Nations' Intergovernmental Panel on Climate Change's (IPCC) “Synthesis Report,” completing the IPCC's Fifth Assessment Report (AR5). [19]

John Coleman wrote the “climate of planet Earth has been constantly changing for 4.5 billion years,” and “climate scientists, the media, environmentalists, bureaucrats, and politicians have all been thinking about climate in a wrong way for decades now.” [19] Coleman continued by stating “we are altering the climate at spots and in minor ways through our activities, but the bottom line is that it is not changing very much and no significant climate change is occurring or likely in the future. There is no climate crisis.” [19]

November 2, 2014

John Coleman appeared on CNN's Reliable Sources with host Brian Stelter, after writing an open letter to UCLA denying the existence of anthropogenic global warming and receiving air time on Fox News to “express his views about climate change to their national audiences.” [16] , [17] Coleman told Stelter that “CNN has taken a very strong position on global warming that it is a consensus. Well there is no consensus in science. Science isn't a vote. Science is about facts,” and that he was “terribly disappointed” by his former network, The Weather Channel, because it “has bought into [climate change]. But so has all the media. That's no big surprise.” [16]

The current CEO of The Weather Channel, David Kenny, published his own open letter “clarifying the channel's belief in global warming because 'some people were confused' by Coleman's comments.” [18] Kenny wrote The Weather Channel was grateful that Coleman got it started 32 years ago, “but he hasn't been with us in 31 years. So he's not really speaking for The Weather Channel in any way today … I think we can all be proud of our resumes, but I would prefer people use the credentials they have today, not the credentials of three decades ago … The climate of the earth is indeed warming … The science is really clear. And I don't like our brand being associated with something that's not scientifically-based.” [18]

October 20, 2014

John Coleman writes an open letter to UCLA and the Hammer Museum, “urging UCLA's Hammer Museum to provide balance to a presentation titled 'Tackling Climate Change Nationally and Globally,'” according to a press release from the Heartland Institute. [15]

Coleman references William Happer, Richard Lindzen, Willie Soon, and John Christy as scientists who “all agree with [his] opening two sentences [of the letter to UCLA] … There is no significant man-made global warming at this time, there has been none in the past and there is no reason to fear any in the future. Efforts to prove the theory that carbon dioxide is a significant 'greenhouse' gas and pollutant causing significant warming or weather effects have failed. There has been no warming over 18 years.” [15]

Coleman states that “it is important to have those attend know that there is no climate crisis”:

“The ocean is not rising significantly. The polar ice is increasing, not melting away. Polar Bears are increasing in number. Heat waves have actually diminished, not increased. There is not an uptick in the number or strength of storms (in fact storms are diminishing). I have studied this topic seriously for years. It has become a political and environment agenda item, but the science is not valid.” [15]

Coleman notes that he is “not a wacko flat-Earther,” nor is he “a 'paid shill' (as has been claimed) of the Koch Brothers,” concluding his letter with a link to Heartland's Nongovernmental International Panel on Climate Change (NIPCC) website. [15] Coleman's open letter to UCLA was sent to numerous local television stations in the Los Angeles area, as well as the Los Angeles Times.

October 9, 2014

John Coleman is quoted in the Heartland Institute's press release, “Heartland Institute Climate Experts Comment on 18 Straight Years of No Global Warming,” which states “the global mean surface temperature has not risen for 18 consecutive years. This extends the so-called 'pause' in global warming to a new record, one not predicted by the climate models of the United Nations' International Panel on Climate Change (IPCC).” [14]

Coleman writes:

Yes there has been no warming for 18 years, but The New York Times has just reactivated it’s environmental global warming/climate change coverage team to increase coverage of what they regard as the most serious issue of our time. At the Times Web site, where it announced this new climate team, I posted this comment:

There has not been any significant man-made global warming in the past, there is none now, and there is no reason to expect any in the future. The computer models that predicted the warming have failed to verify. There has been no warming in 18 years. The ice at the poles is stable. The polar bears are increasing. The oceans are not rising. The march in New York was a political event dominated by communists and socialists who are using climate change as a devise to raise anti-capitalism hell. This is a great distortion of science with a political agenda driven by huge federal tax dollar research grants. I strongly urge the reporter group at the Times to break the really big story and research and see it through: Global warming/climate change has become a politically driven folly without any verified scientific basis. The evidence to support what I have said is there for the looking. Start with the Nongovernmental Panel on Climate Change and the work of Patrick Moore, one of the founders of Greenpeace, and go from there. It can be the investigative story of your lifetimes. Go for it.’

The facts are on the side of the skeptics, but the media remains totally committed to the ‘97 percent consensus’ lie.” [14]

July 7 - 9, 2014

John Coleman was a speaker at the Heartland Institute’s Ninth International Conference on Climate Change (ICCC9) in Las Vegas, Nevada. [13]

DeSmogBlog has done in-depth research on the other speakers and sponsors from Heartland's ICCC9, which can be found here.

January, 2010

Coleman produced a special report for KUSI-TV, entitled Global Warming: The Other Side. The program suggests that Global Warming is a scam and presents what Colement contends is evidence of a deliberate manipulation of world temperature data by NASA and other groups. [7]

It  describes “Climategate” as a “major climate scandal.” Reports have since exonerated the scientists of the Climate Research Unit at the University of East Anglia, finding “no evidence of any deliberate scientific malpractice.”

The Other Side was also supported by the Science and Public Policy Institute (SPPI). The SPPI is a global warming skeptics group founded by climate-change skeptic Robert Ferguson. It's staff includes prominent climate change deniers like Christopher Monckton, listed as SPPI's “Chief Policy Advisor,” and Willie Soon who is listed as their “Chief Science Advisor.

March 8 - 10, 2009

Coleman was a speaker at the Heartland Institute's 2009 International Conference on Climate Change. [8]

November 13, 2008

Coleman gave a presentation to the AWPA San Diego/Imperial Chapter titled “The Global Warming Scam is Wrecking America.” 

Following is a description of the event:

“In the fall of 2007, Mr. Coleman described the current concern over global warming 'a fictional, manufactured crisis, and a total scam.'  In 2008, Mr. Coleman gave a speech of the same tone before the San Diego Chamber of Commerce, blaming the 'global warming scam' and environmentalist lobby for raising gas and food prices.  He also declared the scam 'a threat to our economy and our civilization.'  His posting assessing the science behind global warming can be read at”

March 2008

Coleman's spoke at the Heartland Institute's 2008 International Conference on Climate change, where he accused Al Gore of “financial fraud” and of obfuscating “legitimate debate.”

The Conference describes itself as being created to “generate international media attention.” The Heartland Institute, organizer and funder of the conference, has received over $600,000 from ExxonMobil and over $240,000 from the tobacco industry.

March, 2008

Coleman appeared on the Fox News “Red Eye” where he vowed to sue Al Gore for fraud. Coleman starts by announcing he has found 30,000 “scientists” in doubt of the consensus on global warming. [9]

Coleman's list appears to have originated from the Oregon Petition which was debunked by numerous groups including The Skeptics Society. No lawsuit has yet emerged since Coleman's threat.


Coleman gave a speech before the San Diego Chamber of Commerce, blaming the “global warming scam” and environmentalist lobby, for rising gas and food prices.

He also declared that action to prevent global warming is “a threat to our economy and our civilization.” [10]
