Climate scientists behaving badly? Part 4: what is owed to other enquirers.
Now we move on to what is owed to other enquirers
keep records of original data and methods and make such records freely available.
The global temperature record produced by the CRU is one of the four sets of data on which the IPCC has relied, and in the opinion of many commentators it has been the most influential record and for that reason the most important one. It is therefore a matter of very grave concern that raw data on which it is based no longer exists. It means that no one can check whether the CRU global temperature record is well founded. The fact that it is in line with other records is not the help it appears when we remember that the tuning of the data manipulation underlying those records, and hence the claims for their veracity, has depended significantly on taking the CRU global temperature record as correct. Consequently our acceptance of it depends entirely on the epistemic integrity of the CRU, an integrity which has now been significantly impugned, and is further impugned by the loss of this raw data.
What, then, is their attitude to the obligation to share data? This quotation is illuminating ‘The two MMs [critics of Mann’s statistical techniques] have been after the CRU station data for years. If they ever hear there is a Freedom of Information Act now in the UK, I think I’ll delete the file rather than send to anyone…..We also have a data protection act, which I will hide behind.’.[1]
