Global Warming: Submissions and Responses to Government Inquiries
(Note: for Climategate documents go here.)

US & CANADIAN TESTIMONY
US

  • October 2008 Response to questions from Senator Inhofe of the US Environment and Public Works Committee concerning the validity of climate models for policymaking purposes
  • March 31 2011 There were hearings on climate science before the US House Science, Space and Technology Committee. John Christy of the University of Alabama-Huntsville was a witness and included in his submission a letter I wrote to some members of the incoming Congress on my concerns with some parts of previous IPCC reports.  
  • June 26 2008 US House Committee on Energy and Commerce "Climate Change: Costs of Inaction" plus Responses to follow-up questions from Chairman Dingell
CANADA
  • April 23, 2026. McKitrick, Ross R. Testimony to House of Commons Committee on Environment and Sustainable Development regarding costs of Canada's Industrial Carbon Pricing system. This was around the time the Liberals secured their majority so there's no chance they will care about criticism of their carbon tax plans, but I at least want them to know the costs of what they are proposing to do.
  • ​October 20, 2025 McKitrick, Ross R. (2025) Testimony to House of Commons Committee on Environment and Sustainable Development regarding Canada's 2030 Emission Reduction Plan. My remarks made some very simple points about drivers of emissions (and why we won't meet the Paris target) and the costs of different approaches to emission reductions. I was asked sensible questions by the Conservative members who are trying to understand the economic impacts on their constituents of the government's climate plan. The Liberal and NDP members asked irrelevant idiotic questions and generally had a fit about me telling them they weren't going to meet the Paris target. Not long after the Prime Minister admitted that they weren't going to meet the Paris target. 
  • June 21 2021​ McKitrick, Ross R. (2021) Testimony to the House of Commons Committee on Natural Resources Regarding Biofuels and Renewable Fuels Policy in Canada. Ottawa Ontario, June 21 2021, by videolink.
    • The Government's NR Committee is studying the potential for biofuels and renewable fuels to play a role in reducing greenhouse gas emissions in Canada. I was invited to speak to the Committee on rather short notice. In my presentation I summarize work I have done on this issue in the past as well as some basic principles that guide my thinking about climate policy. 
  • October 18 2018 I testified before the Canadian Senate Committee on Energy, Natural Resources and the Environment hearing on "Social License and the Duty to Consult" which is part of its review of Bill C-69.  Testimony to the Senate Concerning Social License and the Duty to Consult  I have written elsewhere about the problems with the concept of "Social License." In my testimony I make 3 points to the effect that the proposed legislation seems to me to be at odds with the stated intentions behind it. 
  • September 27, 2016 Presentation to a Committee of the Canadian Senate which is looking into the procedures and issues surrounding the approvals of new pipelines in Canada. My written submission is here. 
  • December 15 2011 I testified before the Senate Standing Committee on Energy, Environment and Natural Resources in Ottawa. 
  • April 7 2005 Testimony before the Canadian House of Commons Environment Committee looking into Canada's Kyoto Commitment


ONTARIO

COMMENTS ON REPEAL OF GREEN ENERGY ACT
​I was invited to appear before the Ontario Standing Committee on Social Policy which held hearings on Bill 34, An Act to Repeal the Green Energy Act, October 30 2018. I was not able to meet the committee in person but I submitted written comments.

CORRECTING FALSE CLAIMS IN THE NYC LAWSUIT

The City of New York has filed a lawsuit against a group of large oil and gas companies including Exxon Mobil, alleging among other things that they conspired to mislead the public about the dangers of global warming. Paragraph 87 of the complaint alleges that I was paid by Exxon to do the "hockey stick" work for the Fraser Institute. The claim is completely false and the paragraph is full of untrue statements. I have issued this statement in response:
CRITIQUE OF THE ENDANGERMENT FINDING

​This report is a compilation of review material from many years back and more recent material collected when I re-examined the EPA's handling of criticism from their own Inspector General for the purpose of writing an op-ed. I put it together in response to requests from a number of groups for my input into the question of whether the Endangerment Finding needs to be re-examined. 
  • December 2008 I made a  Submission to the US EPA in response to its Advance Notice of Proposed Rulemaking for greenhouse gases. It includes my letters to Inhofe and Dingell as well as some supplementary material. 
  • September 2007 I was contacted by a politician outside of Canada who was preparing for cabinet-level decisions on global warming policy. I was asked to identify half a dozen of the main assumptions about global warming that, if wrong, would invalidate the usual conclusions. Of course the topic is so big I could easily have written a book in response. A tidied-up version of my actual reply is here. I do not know what effect, if any, it had on the individual's views.
