Climatological uses, it is perhaps easy to overestimate the impact of these problems.
Normal, non-ideology-based scientists question the veracity of the CRU — IPCC flavoured results just because the JBM camaraderie - based group did refuse to honour such requests and people ask the following question: why, if both the empirical results — the raw data (including the nitty - gritty details of the temperature measurements) AND the theoretical model - based machinery are above board and the overall
climatological picture of a man (n)- made warming is pretty much a safe bet, why then would some AGW researchers like the JBM gang refuse to accept that they, too, have got to conform to normal scientific procedure and release the raw data and the details of the theoretical machinery
used to understand those data?
