Stance on Climate Change
“After years of looking, I have not found one piece of empirical evidence that man-made CO2 has a significant impact on global climate.” 
“In the 1980s a small group of individuals became concerned about the Earth's temperature and what it might do in the future. I hesitate to call them scientists because they have abandoned their scientific principals by which their guess about temperature increases and the cause could achieve scientific acceptance or rejection.” 
“NASA’s Aqua satellite is showing that water vapor, the dominant greenhouse gas, works to offset the effect of carbon dioxide (CO2). This information, contrary to the assumption used in all the warming models, is ignored by global warming alarmists.
“… For nearly a decade now, there has been no global warming. Even though atmospheric CO2 has continued to accumulate—up about 4 percent in the last 10 years—the global mean temperature has remained flat. That should raise obvious questions about CO2 being the cause of climate change.
“… The reality is that atmospheric CO2 has a minimal impact on greenhouse gases and world temperature. Water vapor is responsible for 95 percent of the greenhouse effect. CO2 contributes just 3.6 percent, with human activity responsible for only 3.2 percent of that. That is why some studies claim CO2 levels are largely irrelevant to global warming.” 
“… global warming alarmists invariably try to make their case by resorting to rhetoric, dogma, opinion, and emotion. The closest thing to scientific data in their articles is the occasional chart claiming a poorly understood correlation between atmospheric CO2 and the Earth's temperature.” 
“I'm here to encourage everyone to look at the data themselves, not just buy what they’re told. I find that my standards for science are more important to me than anything else, and I hate to see them being depreciated by the alarmists’ claims today. Politics and the media and what have you have allowed us now to be facing one of the biggest scientific hoaxes in history. That’s what's being pushed on us.” 
“But, when it comes to global warming, the public- at-large really doesn’t know whom to believe anymore. And NASA has contributed to that confusion.”

Walter Cunningham appears as a “Key Scientist” in Marc Morano’s documentary film, Climate Hustle, which debuted on December 7, 2015, in Paris, France during the COP21 United Nations summit on climate change.  The film chiefly showcases Morano's personality, a range of discredited scientists, and no new factual information about climate change.
Other notable “Key Scientists” featured in Climate Hustle include: 
- Patrick Moore
- Judith Curry
- Richard Tol
- Ivar Giaever
- Roy Spencer
- Don Easterbrook
- Bob Carter
- Patrick Michaels
- Christopher Monckton
- Anthony Watts

Walter Cunningham 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 Tom Wysmuller and Hal Doiron.

Walter Cunningham is a signatory to an open letter to Pope Francis on climate change. The letter invites the Pope to reconsider his views on climate change before his upcoming encyclical letter on the environment, which is widely expected to call for measures to prevent climate change in the interests of the world’s poor.
The open letter was coordinated and signed by Calvin Beisner of the Cornwall Alliance. According to the letter, “Good climate policy must recognize human exceptionalism, the God-given call for human persons to 'have dominion' in the natural world (Genesis 1:28), and the need to protect the poor from harm, including actions that hinder their ascent out of poverty.” 
Another excerpt below:
”[…] the [climate] models are wrong. They therefore provide no rational basis to forecast dangerous human-induced global warming, and therefore no rational basis for efforts to reduce warming by restricting the use of fossil fuels or any other means.”
Judith Curry comments on her blog Climate Etc. that “Arguably the most effective 'pushback' comes from Cal Beisner of the Cornwall Alliance, who coordinated An Open Letter to Pope Francis on Climate Change.” 
Walter Cunningham attended a meeting of the Senate Space, Science and Competitiveness subcommittee, chaired by republican Senator Ted Cruz, as reported in a Scientific American article titled “The Shifting Politics of NASA's Astronaut Program.”
In Cunningham's written testimony (PDF), he suggests that “NASA should be more on their science obligations and avoid any associated political issues,” specifically that “humans are the cause of global warming.” Cunningham said that “The space agency compromises its scientific credibility by participating in the politics surrounding one of the great scientific hoaxes in history.” .

DeSmogBlog has done in-depth research on the other speakers and sponsors from Heartland's ICCC9, which can be found here.
“The climate on our planet has been changing for billions of years. And life on our planet has evolved by adapting to those changes. Today, global warming alarmists want us to believe that climate change is a threat to our civilization when it really is a program for governmental control of our energy consumption and our standard of living. One of the greatest scientific hoaxes in history,” Cunningham said in his speech. 
Walter Cunningham gave a speech at a CFACT Collegians event at the University of Minnesota, and was interviewed by the ABC Affiliate KSTP. The story was re-posted at Somewhat Reasonable, the Heartland Institute's blog. Cunningham had this to say:
“I'm here to encourage everyone to look at the data themselves, not just buy what they’re told. I find that my standards for science are more important to me than anything else, and I hate to see them being depreciated by the alarmists’ claims today. Politics and the media and what have you have allowed us now to be facing one of the biggest scientific hoaxes in history. That’s what’s being pushed on us.”

In an interview with Larry Bell in a Forbes article titled “A Conversation With Apollo Astronaut Walter Cunningham About A Vital Need To Restore Climate Science Integrity,” Walter Cunningham takes the opportunity to explain why he “is an outspoken critic of pseudo-scientific climate alarmist claims.”
According to Larry Bell, “when it comes to global warming, the public- at-large really doesn’t know whom to believe anymore. And NASA has contributed to that confusion.” He says that NASA should be “emphasizing to the media that human- caused global warming is a hypothesis, not a scientific fact.”
- 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.

Cunningham was one of 49 former NASA scientists to sign an open letter to NASA and the Goddard Institute for Space Studies (GISS) to cease their “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.
May 16 - 18, 2010
The Heartland Institute published an article by Cunningham titled “Global Warming Fact Versus Faith: One Astronaut's Views” (PDF).
In his article, Cunningham argues that climate change skeptics “hold the high ground scientifically” over those who accept man-made climate change. He frames the debate as being similar to “the battle over evolution versus creationism” where “facts are pitted against faith and science against religion.”
In Cunningham's view, those who accept man-made climate change “Faith” while skeptics are on the side of “Science.” As evidence for this view, he cites a (since debunked) U.S. Senate Environment and Public Works Committee report that “identifies 700 prominent scientists who have publicly repudiated the alarmist position on global warming.” 
He additionally cites the Oregon Petition (which was also debunked) as proving that there is “convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate.”
