Hans H.J. Labohm


  • Drs. (Doctorandus). [14] While a number of sources (here, and here for example) identify Hans Labohm as having a PhD [12], [8], this appears to be a confusion over the term “Doctorandus” which is a Dutch academic title equivalent to a MA or MSc degree. Labohm studied Economics and Economic History at the University of Amsterdam. [13]


Hans Labohm was past Advisor and Senior Visiting Research Fellow to the Netherlands Institute of International Relations, Clingendael, from 1992 to 2005. He is now an independent economist and publicist. Labohm describes himself as the “unofficial coordinator” of the network of Dutch climate change skeptics. He also a member of De Groene Rekenkamer (The Green Court of Audit), a little-known Dutch anti-environmental group with conservative ties and links to many of the Dutch climate change skeptics. [1], [14]

Labohm has written for various Netherlands newspapers in the Netherlands including Het Financieele Dagblad, Trouw, NRC Handelsblad, and De Volkskrant. Labohm also has a regular column at the Dagelijkse Standaard, a conservative web blog started by Joshua Livestro (once an advisor for Sarah Palin on matters relating to Europe's economy). Labohm has also been a regular contributor to Tech Central Station (TCS). [2]

Stance on Climate Change

“I started as an anthropogenic global warming believer, then I read the [UN's IPCC] Summary for Policymakers and the research of prominent skeptics.” “After that, I changed my mind” [3]

Key Quotes

“Nevertheless, in my capacity as expert reviewer of the IPCC, I have also received (a tiny) part of the Nobel price, which has been awarded to Al Gore and the IPCC (yes, thanks for your congratulations). Should I be grateful? I don't think so. Both 'An Inconvenient Truth' and the latest IPCC report labour under cherry-picking, spindoctoring and scare-mongering (Al Gore's movie more than the IPCC reports). Awarding the Nobel price for such flawed science is a disgrace” [4]

Note: Although Labohm describes additionally described as an IPCC “Expert Reviewer,”this does not mean that the IPCC officially requested him to review any of their documents.

Key Deeds

August, 2016

Hans Labohm is listed as a “Founding Member” of group named Climate Exit (Clexit) led by climate change denier Christopher Monckton. According to Clexit's founding statement (PDF), “The world must abandon this suicidal Global Warming crusade. Man does not and cannot control the climate.” [20][21]

Desmog reports on how the group grew in the wake of the UK's decision to leave the EU. A key member of Clexit's “60 well-informed science, business and economic leaders” is Hugh Morgan, a former board member of the Reserve Bank of Australia and former CEO of Western Mining Corporation with close ties to Australia's Liberal party. [22][23]

According to Clexit's founding statement

If the Paris climate accord is ratified, or enforced locally by compliant governments, it will strangle the leading economies of the world with pointless carbon taxes and costly climate and energy policies, all with no sound basis in evidence or science […]” [21]

April, 2006

Labohm was a signatory to the 2006 open letter to Prime Minister Stephen Harper that recommended the government stall any action on climate policy because the “climate changes all the time due to natural causes.” [5]

The letter was signed by numerous other “accredited experts” including Richard Lindzen, Roy Spencer, Sonja-Boehmer Christiansen, Vincent Gray, and Fred Singer.

May, 2004

Labohm was a speaker at the Heartland Institute's fourth International Conference on Climate Change (ICCC4) in Chicago. [24]  

DeSmog has done research on the co-sponsors of the conference and found that 19 of the 65 sponsors (including Heartland itself) have received a total of over $40 million in funding since 1985 from ExxonMobil, Koch Industries family foundations or the Scaife family foundations.  

Labohm's speech, titled “Climate Change: Political, Social and Economic Implications” can be viewed below. 

December 13, 2007

Signed an open letter to the UN's Secretary-General Ban Ki-Moon. The letter states that “the IPCC’s conclusions are quite inadequate as justification for implementing policies that will markedly diminish future prosperity.” [6]



Although Labohm has not published original research in peer-reviewed journals, he recently disputed this claim, saying that his following articles had received more peer review than Michael Mann's Hockey Stick:

  • “Klimakatastrophenzweifel – eine Einführung” (translated to  Novo Magazine (Jan./Feb. 2007). 

Novo Magazine does not appear to be a peer-reviewed journal by traditional standards.

  • “What is Wrong with the IPCC?” (PDF) Science and Public Policy Institute, November 2007.

The Science and Public Policy Institute (SPPI) is a global warming skeptics group led by Robert Ferguson, a past director of the Center for Science and Public Policy (CSPP). SPPI prominently features publications by climate skeptics including Christopher Monckton

According to the Amsterdam Law Forum's Peer Review Process, “Amsterdam Law Forum provides an alternative to the current scholarly publishing paradigm, allowing for innovation and experimentation in scholarly communication. The journal is not peer reviewed at this moment. It is the ambition of the Amsterdam Law Forum to offer a full peer review process in the future.” [11]


Labohm co-wrote a book titled Man-Made Global Warming: Unravelling a Dogma, published by Multi-Science Publishing in 2004.  The other authors were Simon Rozendaal, a journalist, and Dick Thoenes, a chemical engineer. 

The premise of Unravelling a Dogma is that the current science on global warming is “not strong enough to scientifically prove that manmade global warming exists.”
