Arthur Rörsch was a genetics professor at Leiden University in the Netherlands from 1967 to 1997.

Rörsch is on Senator James Inhofe’s list of “Prominent Scientists” who deny the existence of man made climate change. He is one of 49 on the list who are retired.

Stance on Climate Change

“Doubts about the mainstream ‘CO2-paradigm’ arise because there is so little evidence from direct observations to support the framework that has been constructed from computer model studies/experiments. This alone should be a sufficient reason for the scientific world to consider alternative paradigms.”2Arthur Rörsch. “Guest Editorial” (PDF), Energy & Environment, Vol. 21, No. 4 (2010).

Key Quotes

“The observed coincidence between global warming and rise of CO2 in the atmosphere over the last century – more accurately measured over the last 30 years of it – need not indicate a causal relationship, and it certainly need not give rise to global catastrophe.”3Arthur Rörsch. “Guest Editorial” (PDF), Energy & Environment, Vol. 21, No. 4 (2010).

Singnatory to an open letter to UN Secretary-General Ban Ki-Moon that claims “It is not possible to stop climate change, a natural phenomenon that has affected humanity through the ages.”6Open Letter to the Secretary-General of the United Nations,” December 13, 2007. Reprinted by the Science and Public Policy Institute.

Signatory to an open letter to Stephen Harper urging inaction on climate change policy.


  • [Pending further investigation.]


According to a search of 22,000 academic journals, Rörsch has published 20+ original research papers in peer-reviewed all in the area of genetics. His most recent research was published over eight years ago, prior to which he published in 1977.

Many of Rörsche’s papers on climate change (here, here, and here, for example) were published in the skeptical journal Energy and Environment, edited by Sonja Boehmer-Christiansen, and described as one of the journals that skeptics can go to when they are unable to publish their work elsewhere.
