16 May 2012 – Professor Fritz Vahrenholt, former environment senator and CEO of RWE Innogy, told Welt Online his thesis that global warming will be significantly less substantial than previously thought. By the end of the century, he believes, there will be just an increase of one degree Celsius. He believes the influence of the sun on the Earth’s climate has been significantly underestimated until now.

Vahrenholt told Welt Online that he had been an active supporter of the CO2 theory, but then experienced two pivotal moments that saw him reassess his position.
“First, I was invited in February 2010 as a scientific reviewer for the Intergovernmental Panel on Climate Change (IPCC) report on renewable energy in Washington. There, I realised that the drafting of the report was done in anything but a scientific manner. The report is littered with errors. At the end, representatives of Greenpeace edited the final version. The result was the nonsensical claim that 80% of total world energy needs can be met with renewable energy.
“These developments shocked me. I thought, if such things can happen in this report, then they might happen in other IPCC reports too. Of the 34 members of the IPCC Secretariat, the bulk are from the global South – such as Cuba, Sudan, Madagascar, Iran or China. These countries all have an interest in transfer payments. Until then, I had thought researchers would meet and discuss. No, in fact these are delegates representing nation states – and not always democratic ones. They represent interests and exert influence.”
In responding to Welt Online’s point that scientists in Germany and elsewhere are still mostly convinced that mankind is largely responsible for climate change through the emission of CO2, Vahrenholt says, “But these scientists are not asked what the final report text looks like. They are merely quoted. And there is tremendous pressure on scientists to conform to the mainstream. If you fail to do so, then you will no longer receive any funding or you will be excluded from conferences and talks. This happened to myself. The University of Osnabrück has excluded me from an invited lecture because I have written this book (The Cold Sun: Why the climate catastrophe will not happen) Dissenting opinions are no longer allowed.”
Vahrenholt says, “I am not a climatologist, of course, but I work in the same way as the IPCC. I look at thousands of scientific publications on the topic. In my book I also provide a forum to those whose publications that have been removed by the shortening of the IPCC’s final report. The so-called core writing team of the IPCC, which selects the material according to policy objectives, is made up to 30% of people who are affiliated with Greenpeace and the WWF. I had not known that fact previously.”
