According to his biography at the Seventh International Conference on Climate Change, Harold Doiron is known for his experience in eliminating unstable vibrations in liquid propellant rockets.

He organized and led the NASA/industry team, titled the “Pogo Prevention Panel”
that successfully eliminated this pogo stick vibration problem from the Space Shuttle design.

Stance on Climate Change

According to an open letter signed by Doiron,

“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… . With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled.” [2]

Key Quotes

“Public policy decisions with potential major changes to energy use in the USA to affect climate change, should have more engineering input … The Physics, chemical, biological and heat transfer processes involved in Climate Change modeling and analysis are similar to large, complex systems familiar to Aerospace Engineers.” [3]

Hal Doiron 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 Walter Cunningham. [16]

Harold Doiron 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.” [9]

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 Etcthat “Arguably the most effective 'pushback' comes from Cal Beisner of the Cornwall Alliance, who coordinated An Open Letter to Pope Francis on Climate Change.” [10] 

April 27, 2015

Hal Doiron presented in the Vatican City, Italy, along with skeptics such as Christopher Monckton and Calvin Beisner of the Cornwall Alliance, for a press event hosted by the Heartland Institute in order to “dissuade Pope Francis from lending his moral authority to the politicized and unscientific climate agenda of the United Nations,” according to a Heartland Institute press release. [14], [15]

Video below:

DeSmogUK attended the event and noted that “just nine journalists made up the audience at Heartland's press conference.”

September 25, 2014

Harold Doiron attends the “At the Crossroads; Energy & Climate Policy Summit” in Houston, Texas, hosted by the Texas Public Policy Foundation and The Heritage Foundation. Doiron presents in “Panel I: The State of the Science,” with Judith Curry and Roy Spencer. [8]

July 7 - 9, 2014

Harold Doiron was a speaker at the Heartland Institute’s Ninth International Conference on Climate Change (ICCC9) in Las Vegas, Nevada. [7]

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

March, 2013

Harold Doiron is part of a group that calls themselves “The Right Climate Stuff” (TRCS). According to a comment by a user identifying himself as Harold Doiron on the SkepticalScience website, Doirin is the Leader and Chairman (Unconfirmed) of TRCS[18]
On March 15, 2013,  Doiron, alongside Thomas Wysmuller, Walter Cunningham, 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.” [11]
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.
The group also presented at the Heartland Institute's 7th International Conference on Climate Change (ICCC-7) in 2012 in Chicago. 
January, 2013
Harold Doiron was on a Panel at the National Press Club titled “Climate Change - Science or Hype.” Panelists included H. Leighton Steward from Plants Need CO2, Scott Sklar of The Stella Group, Daniel Wiess of the Center for American Progress, Monical Dorhoi of World Bank, Keven Book of CleanView Energy Partners and David Kruetzer of the Heritage Foundation[12]
At the debate, Harold Doiron described The Right Climate Stuff (TRCS) as a “Volunteer group.” He added,  “I think we’re very objective. We don't belong to any special interest group. […] Our conclusion is humans are not (causing) a significant warming of this planet.”
In an interview with StateImpact, Harold Doiron described why he and 20 of his colleagues became involved in the group. In Doiron's case, James Hansen was the trigger: “Well, the thing that really pushed me over the edge was the public statements of NASA’s chief climate scientist Dr. James Hansen,” Doiron said. [13]

May 21, 23, 2012

Doiron registered as one of four former NASA scientists and astronauts to speak at the Heartland Institute's Seventh International Conference on Climate Change (ICCC7). [4]

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.

March 28, 2012

Doiron 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.” [2]

SkepticalScience published a critique on the claims made in the letter, which was also republished in The Guardian. [5], [6]

September 12, 2011

Harold Doiron was a member of the organizing committee for the JSC NAL Symposium on Climate Change where he delivered the opening remarks (PDF).

“Our speakers today could be generally classified as being on the side of the debate that argues that Catastrophic Anthropogenic Global Warming (CAGW) is an unproven theory with very little credibility,” Doiron said.

Walter Cunningham was also a speaker at the event. [3]
