Shut up. They are smarter than you.
The UN's Intergovernmental Panel on Climate Change (IPCC) issued its long awaited pronouncement last Friday in Paris and I am informed by the media that this most definitive of all documents closes the debate on anthropogenic climate change. Now is the time for action, no more discussion will be allowed. I have read the document, and most assuredly it does use uncompromising language ascribing recent global warming to human activity. The science in the document, which I am told was reviewed by 300 eminent scientists, at first sight appears to be impeccable, but I must admit that was a little perturbed to find on page 5 that 0.16 + 0.077 + 0.21 + 0.21 = 0.28 rather than 0.657. I must not fully understand that esoteric form of mathematics known as addition. This level of ignorance on my part clearly shows that I am incapable of judging the merits of the science on my own and I give thanks to the IPCC for taking this burden off my shoulders.
