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]

Key Deeds

May 12, 2015

Harold Doiron signed an open letter to Pope Francis on climate change inviting the Pope to reconsider his views on climate change before his encyclical letter on the environment. [9]

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.”  [10] 

An additional 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.”

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]

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.

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]

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]

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.”
