A high-level inquiry into the Intergovernmental Panel on Climate Change found there was “little evidence” for its claims about global warming.
It also said the panel had emphasised the negative impacts of climate change and made “substantive findings” based on little proof.
The review by the InterAcademy Council (IAC) was launched after the IPCC’s hugely embarrassing 2007 benchmark climate change report, which contained exaggerated and false claims that Himalayan glaciers could melt by 2035.
*** DEBATE: IS CLIMATE CHANGE AND GLOBAL WARMING JUST A CON?...***
The panel was forced to admit its key claim in support of global warming was lifted from a 1999 magazine article. The report was based on an interview with a little-known Indian scientist who has since said his views were “speculation” and not backed by research.
Independent climate scientist Peter Taylor said last night: “The IPCC’s credibility has been deeply dented and something has to be done. It can’t just be a matter of adjusting the practices. They have got to look at what are the consequences of having got it wrong in terms of what the public think is going on. Admitting that it needs to reform means something has gone wrong and they really do need to look at the science.”
Climate change sceptic David Holland, who challenged leading climate change scientists at the University of East Anglia to disclose their research, said: “The panel is definitely not fit for purpose. What the IAC has said is substantial changes need to be made.”
The IAC, which comprises the world’s top science academies including the UK’s Royal Society, made recommendations to the IPCC to “enhance its credibility and independence” after the Himalayan glaciers report, which severely damaged the reputation of climate science.
