“Pseudoscientific elements in climate change research” by Arthur Rosch – published by the Science and Public Policy Institute, Feb 16, 2008
Alarming statements from the UN Intergovernmental Panel on Climate Change (IPCC) concerning global warming are being challenged by a considerable number of scientists from different disciplines with a variety of arguments. The disputes comprise the collection and interpretation of data, the validation of hypotheses and climate models, the use of those models for scientific decision making, and the quality of the scientific discourse on these matters.
Many of the critical scientists are not directly involved in climate research. This brings into focus the weight to be given to views of experts relative to that of non-experts when the use of the scientific method is discussed in general, and a critique on the use of the peer review system in scientific journals that is supposed to safeguard the quality of science.
The concern of some climatologists and scientists from other disciplines is that the supposed dangerous warming seems to be exaggerated.
The possible causes of exaggerated conclusions are investigated. It is concluded that the general practice of parameterization of computer models in climate change research shows an element of pseudo science because it leads to self-confirmation of input hypotheses (dogmas) and insufficient challenge of theories.
The theory of the enhanced greenhouse effect of increasing CO2 concentrations in the atmosphere – the very basis for alarming messages concerning future climate change – is itself largely a modelling concept. It is suggested, that for the sake of the progress of science, this theory requires reinvestigation.
