Dr. Roy Clark





Dr. Roy Clark is a retired engineer who has over 30 years of experience in new product and process development with emphasis on optical and spectroscopic measurements in adverse environments.
He has successfully integrated complex laser diagnostics into large scale hypersonic and high energy laser test facilities. He has also developed LED and fiber optic illumination systems and sensors for a wide range of applications. His spectroscopic experience extends from 200 nm to 200 cm-1 including work with circular and linearly polarized light. His interests also include time based calibration techniques that are directly traceable to the primary atomic clock standard. He has worked at several large and small companies in S. California and has provided consulting services for optical systems development. He has 8 US patents. He received his MA in chemistry from the University of Oxford University and his Ph.D. in chemical physics from Sussex University (UK 1976).
He started his own research on climate change in 2007. His particular interest is time dependent or dynamic surface energy transfer and the calculation of surface temperatures from first principles. This includes the use of detailed high resolution radiative transfer calculations to evaluate the effect of molecular line broadening effects on the LWIR flux in the troposphere. He has published several technical articles on climate change and a book on the ‘Dynamic Greenhouse Effect’.



Dr. Arthur Rörsch





The late Dr Arthur Rörsch (1933-2020) had a degree in chemical engineering from the University of Delft (1957), and a cum laude PhD from the University of Leiden (1962). He was a Knight in the Order of the Dutch Lion (1994).

He was Professor of Molecular Genetics at the Medical Faculty of Leiden University from 1967 to 1998 and Professor of Biochemistry at Leiden University from 1973 to 1980 at the Faculty of Science, Leiden University. He also served as member, and subsequently vice-president, of the board of management of the Netherlands Organization for Applied Research, TNO from 1979 to 1994, with special responsibility for the research fields of Public Health, Food & Agriculture, and Environment. As a student he was secretary of the department ‘Delft’ of the Netherlands Association for Meteorology and Astronomy.

On a European level he was involved in committees on the assessment of the quality of EU projects and the performance of scientific institutions. As Secretary-General of the European Molecular Biological Conference (a political body of 10 member states at the time), he has been active in the interaction between science and government policy. As chairman of the National (Dutch) Council for Agricultural Research he worked on the development of scenarios for four years (1995-1999).

He was the guest editor for two special climate issues published by Energy and Environment in 2010 and 2013: Paradigms in Climate Research (E&E Volume 21, Number 4) and Mechanisms of Climate Change and the AGW Concept: a critical review (E&E Volume 24 Number 3 & 4). He also published a more general discussion of climate research, including the role of the Intergovernmental Panel on Climate Change (IPCC) in “The Progress of Science – Past, Present and Future” that was published in the journal Humanities in 2014.
