“There are many casualties in this sad story of greed and hubris. The big victim is the scientific method. This was pointed out in great detail by John P Costella of the Virginia-based Science and Public Policy Institute. Science is based on three fundamental pillars. The first is fallibility. The fact that you can be wrong, and if so proven by experimental input, any hypothesis can be—indeed, must be—corrected.

This was systematically stymied as early as 2004 by the scientific in-charge of the University of East Anglia’s Climate Change Unit. This university was at the epicentre of the ‘research’ on global warming. It is here that Professor Phil Jones kept inconvenient details that contradicted climate change claims out of reports.

The second pillar of science is that by its very nature, science is impersonal. There is no ‘us’, there is no ‘them’. There is only the quest. However, in the entire murky non-scientific global warming episode, if anyone was a sceptic, he was labelled as one of ‘them’. At the very apex, before his humiliating retraction, Pachauri had dismissed a report by Indian scientists on glaciers as “voodoo science”.

The third pillar of science is peer group assessment. This allows for validation of your thesis by fellow scientists and is usually done in confidence. However, the entire process was set aside by the IPCC while preparing the report. Thus, it has zero scientific value.

The fact that there was dissent within the climate science teams, that some people objected to the very basis of the grand claims of global warming, did not come out through the due process. It came to light when emails at the Climate Research Centre at East Anglia were hacked in November 2009. It is from the hacked conversations that a pattern of conspiracy and deceit emerge. It is a peek into the world of global warming scaremongering—amplify the impact of CO2, stick to dramatic timelines on destruction of forests, and never ask for a referral or raise a contrary point. You were either a believer in a hotter world or not welcome in this ‘scientific fold’.

There’s plenty more in this sordid tale. For one thing, there is no scientific consensus at all that man-made CO2 emissions cause global warming, as claimed by the IPCC. In a recent paper, Lord Monckton of Brenchley, who has worked extensively on climate change models, argues: ‘There is no scientific consensus on how much the world has warmed or will warm; how much of the warming is natural; how much impact greenhouse gases have had or will have on temperature; how sea level, storms, droughts, floods, flora, and fauna will respond to warmer temperature; what mitigative steps—if any—we should take; whether (if at all) such steps would have sufficient (or any) climatic effect; or even whether we should take any steps at all.’

An investigation by Dr Benny Peiser, director, Global Warming Policy Foundation, has revealed that only 13 of the 1,117, or a mere 1 per cent of the scientific papers crosschecked by him, explicitly endorse the consensus as defined by the IPCC. Thus the very basis of the claim of consensus on global warming is false. And so deeply entrenched is the global warming lobby, the prestigious journal Science did not publish a letter that Dr Peiser wrote pointing out the lack of consensus.

Thus the earth has warmed at this rate at least twice in the last 100 years and no major catastrophe has occurred. What is more, the earth has cooled after that warming. Why is the IPCC not willing to explore this startling point?”
