Given the last 30 years there is no reason to believe, from a policy
perspective, that spending more money
on climate change will lead to any more certainty about
climate sensitivity.
If Andrew Neil knew more about the science he might understand 1) how biased a
perspective his chosen lines of questioning sometimes give
on AGW, 2) that the IPCC's (AR4) suggested range for
climate sensitivity is in line with the large body of evidence
on the subject, and 2) how out
on a limb scientists such as Judith Curry and Roy Spencer are from the mainstream evidence - based consensus.
