THE notion that human activity has an alarming influence on climate is based on Intergovernmental Panel on Climate Change reports and spurious claims about a scientific consensus.
Independent scientists who question these claims are accused of being in the pay of the energy industry and of believing that the notion of man-made climate change is a conspiracy.
To the best of my knowledge, no climate conspiracy has ever existed. But another force has driven science into its present parlous state where the output of computer software is held in higher regard than observational data, where marketing spin is more important than fact and evidence, and where a trenchant defence of the notion of man-made global warming is seen as paramount.
The single, pre-eminent force driving this distortion of science originates in the once-august UN. The UN's Framework Convention on Climate Change set the tone by linking climatic variations to the air and water pollution issues that it was quite reasonably addressing at the time. It ignored recognised natural climate forces and declared that recent variations in climate were attributable to human activity. Although the IPCC, which was set up by the UNFCCC to investigate the matter, backed away from the assertion that all modern climate change is man made, it nonetheless operates under a charter that considers only the risks of "human-induced" climate change.
