Harold H. Doiron
- Ph.D., Mechanical Engineering, University of Houston (1970).
- B.S., Physics, Mathematics, University of Louisiana at Lafayette (1963).
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.” 
“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.”

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.” 
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.”

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. ,

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.

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

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.

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.”

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. 
NASA Alumni League JSC Chapter — Member (PDF).
InDyne, Inc. — Past VP, Engineering Analysis and Test Division.
McDonnell Douglas/Boeing — Past Sr. Manager, Loads and Dynamics.
Reed Tool Company — Past Director, Technical Services and Field Engineering. Studied methods to reduce costs of drilling for oil and gas, and provided “drilling bit applications technical support, oil and gas well drilling planning.”
NASA Johnson Space Center — Past Aerospace Technologist.
According to a search of Google Scholar, Harold Doiron has not published in peer-reviewed journals on the subject of climate.
He has published some articles on engineering, space structures, and “space shuttle pogo prevention.”
