Unprovable claims attributing weather patterns and events to anthropogenic CO2 emissions have been around for some.
A new paper from a group of IPCC authors in conjunction with the re-insurance industry, now claim they have found the Holy Grail; they can definitely say that the year 2000 floods in the British Isles were made worse by global human CO2 emissions and they imply that they can make this attribution for any event in the future.
The paper uses convoluted climate modelling to focus on one season of unusual rainfall in the UK, the fall of 2000. There is a negligible long term trend in precipitation in this 235 year record. The modelling results were aggregated by feeding modelling programs to home PC users in the UK and around the world and running thousands of simulations on those computers.
A previous exercise of this kind on temperature produced unusable results, with temperature ranges extending to a rise of 11 degrees C from a doubling of CO2, three times higher even than the IPCC’s own inflated figures and 11 times higher than the effect quoted by many climate scientists.
