Fritz Vahrenholt: I used to believe that we were to blame for global warming, but now I’m not so sure
SCIENTISTS of the Intergovernmental Panel on Climate Change (IPCC) are quite certain: by using fossil fuels man is currently destroying the climate and our future. We have one last chance, we are told: quickly renounce modern industrial society – painfully but for a good cause.
For many years, I was an active supporter of the IPCC and its CO2 theory. Recent experience with the UN's climate panel, however, forced me to reassess my position. In February 2010, I was invited as a reviewer for the IPCC report on renewable energy. I realised that the drafting of the report was done in anything but a scientific manner. The report was littered with errors and a member of Greenpeace edited the final version. These developments shocked me. I thought, if such things can happen in this report, then they might happen in other IPCC reports too.
Good practice requires double-checking the facts. After all, geoscientists have checked the pre-industrial climate, over the past 10,000 years: this isolates natural climate drivers. According to the IPCC, natural factors hardly play any role in today's climate so we would expect a rather flat and boring climate history.
