Worse still, there are even controversies about the basic data on temperature. The series going back one, 10 or 100,000 years are, in the genuine sense of the word, synthetic. They are not direct observations but are melded together from proxies such as ice cores, ocean sediments and tree rings.
Given the extent to which the outcome is affected by the statistical techniques and the weightings applied by individual researchers, it is essential that the work is done as transparently as possible, with the greatest scope for challenge. That is why the disclosure of documents and e-mails from the Climatic Research Unit is so disturbing. Instead of an open debate, a picture is emerging of selective use of data, efforts to silence critics, and particularly a refusal to share data and methodologies.....
....We need to purge the debate of the unpleasant religiosity that surrounds it, of scientists acting like NGO activists, of propaganda based on fear, for example, the quite disgraceful government advertisement which tried to frighten young children-the final image being the family dog being drowned-and of claims about having “10 days to save the world”. Crude insults from the Prime Minister do not help.
