SCIENCE A SLAVE TO EXPEDIENCY

"...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. " John McLean writes in The Australian.

 

Science a slave to expediency

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.

Raising these matters under the UN banner was a political masterstroke because it drew national governments into the process. UN bodies have a reputation for political allegiances rather than peer-group pressure but the result is much the same, and even more so when government appointees, often fervent believers in the cause, speak passionately and seem backed by UNauthority.

No individual or government had the temerity to stand up to the UNFCCC or IPCC and say, "we don't agree". Some stridently endorsed the claims, and many interpreted the statement, "we don't know what else might be causing climate change, so it must be human activity" as proof positive rather than admission of incomplete knowledge.

The IPCC has now delivered four scientific assessment reports, each accompanied by an increasingly urgent call to action regarding climate change driven by greenhouse gases. National governments, which are signatories to the UNFCCC, have almost without exception bought into the alarm, modulating it only to accord better with their own political philosophies. This, combined with the allocation research funding according to policy relevance, means governments now attempt to predetermine the findings of scientific research.

For many years climate researchers have understood that their proposals will only be funded if they are pitched in line with government policy. Even worse, unless some aspect of their results appears to perpetuate government thinking, renewal of their funding is unlikely. Other climatologists are acutely aware of the potential consequences for their employers and their own employment prospects should they speak out in criticism of the dominant alarmist paradigm. Scientists who have criticised the hypothesis of human-caused climate change have had their funding curtailed or employment terminated.

Climate modellers have been very aware that their expensive and powerful computing facilities would be supported only if their research produced alarmist climate predictions. This notwithstanding, these models often produced results that were not in good agreement with historical data, perhaps because they poorly replicated or even omitted variations in climate.

These deficiencies and more have been papered over by reviving outdated and inaccurate research about the warming effect of carbon dioxide. The numbers still didn't add up but the inclusion of some "positive feedbacks" masked the problem, and the models were declared "proof" of a significant human influence on climate.

The peer-review process was originally a sanity check for the editors of scientific journals but has always been open to abuse by reviewers who wish to support or suppress a particular line of argument. The recent narrow focus of climate research funding has caused an outburst of scientific papers that support the IPCC's alarmist beliefs and relatively few papers that contradict it. Reviewers with vested interests suppress contradictory papers and support the "official" line.

Vested interests now dominate climate science. Whether climatologists, their employers and other people believe the government-approved line has become irrelevant, because they all wish to retain an income stream and whatever reputations they've established. These people advise governments, which subsequently set policy and research funding regardless of any contradiction with observational data.

Climate science is no longer an impartial truth but a slave to the yoke of politics and opportunism. If this continues, society will be the inevitable loser.
