Dr. Boris Winterhalter is a retired Senior Marine Researcher of the Geological Survey of Finland, and former professor of marine geology at University of Helsinki.

He operates three blogs (in Finnish). The first, Ilmasto on luonnostaan muuttuva (roughly translating to “the climate is naturally variable”) which “deals mainly with political issues and my critique of the offical climate doctrine in Finland.”

His second blog, Ilmastonmuutos ja riippumaton tiede (roughly translated to “Climate change and the related science and belief”) covers “mainly scientific issues related to the hype of climate change.” [2]

His third blog is titled Ilmastonmuutos - totta vai tarua, or “Skeptic's thoughts.”

Stance on Climate Change

Winterhalter is a signatory to the “Climate Scientists's Register,” which states that “We, the undersigned, having assessed the relevant scientific evidence, do not find convincing support for the hypothesis that human emissions of carbon dioxide are causing, or will in the foreseeable future cause, dangerous global warming.” [3]

Key Quotes

“Although some outflow glaciers are retreating in Greenland, it seems
that the net accumulation of snow counteracts this loss in ice and
there is no imminent danger of sea level rise.

“In northern Europe we enjoy a temperate climate thanks to the
prevailing south-westerlies and there are no indications of a change in
pattern.” [4]

“The effect of solar winds on cosmic radiation has just recently been established and, furthermore, there seems to be a good correlation between cloudiness and variations in the intensity of cosmic radiation. Here we have a mechanism which is a far better explanation to variations in global climate than the attempts by IPCC to blame it all on anthropogenic input of greenhouse gases.” [5]

Key Deeds

February 23, 2017

Boris Winterhalter was a signatory of a petition (PDF) organized by Richard Lindzen of the Cato Institute urging President Donald Trump to pull the United States out of the United Nations international convention on climate change (UNFCCC). [7]

In just a few weeks, more than 300 eminent scientists and other qualified individuals from around the world have signed the petition below,” Lindzen wrote in the letter. [7]

Media outlets including Fox News, The Hill, and the Daily Caller reported on the list, describing signatories as “eminent scientists” and “qualified individuals.” [8], [9], [10]

DeSmog investigated the list, and found that only a small handful of the signatories could be considered “even remotely ‘qualified’ or ‘eminent’ — but not in the field of climate science.” The list included individuals “interested in climate,” and one signatory who only identified as an “emailer who wished to sign the petition” while some signers provided no affiliation or address whatsoever. [11]

November, 2010

Winterhalter is listed as a signatory of the International Climate Science Coalition's “Climate Scientists' Register.” [3]

February, 2007

Winterhalter is listed as a reviewer of the Independent Summary for Policymakers (ISPM) of the IPCC Fourth Assessment Report. [6]

The ISPM is published by the Fraser Institute and is critical of the IPCC. The Fraser Institute receives funding from several tobacco companies, and has received $60,000 from ExxonMobil.



According to a search of 22,000 academic journals, Winterhalter has not published peer-reviewed research on climate.

He has had four peer-reviewed articles, all related to marine geology, the first published in 1970, the rest between 2000 and 2002.
