"IPCC: separating fact from fright"

Here.

Excerpt:

The reason the IPCC matters so much in public debate is not because it provides us with a summary of current climate science (which the workgroup reports do attempt to do, for better or worse), but because it provides leaders, commentators and activists with something else entirely: ‘The Science.’ This product may look like a set of scientific statements, but is in many ways the exact opposite of science. ‘The Science’ is ‘unequivocal’ rather than sceptical and cautious in its conclusions; ‘The Science’ is built on an artificial consensus rather than on a real battle of competing ideas that admits the possibility that current thinking could be completely wrong; ‘The Science’ very strongly implies a particular direction for policy (greenhouse gas emission reductions) which is apparently above politics, rather than merely informing a political debate about how we take society forward on the basis of human need and desire.
