Long-term readers may remember my efforts to get the International Journal of Climatology to adopt a sensible policy on data and materials - this was prompted by Steve McIntyre's attempts to extract information from the journal and one of its authors, Ben Santer.
At that point the journal had no policy, simply referring requesters to the author, and apparently happy to let the authors refuse if they wished. IJOC is a journal of the Royal Meterological Society, and the society's head, Paul Hardaker, was initially very favourable, with an undertaking to instigate a review. However, as months turned into years it became fairly clear that the society was caught between a rock and a hard place. If their policy was tough enough to ensure that data became disclosable then mainstream climatologists would not publish there. Climategate brought some confirmation of this, with the revelation of an email in which Santer and Jones discussed a boycott of the journal over a future data policy. Santer's words:
If the RMS is going to require authors to make ALL data available - raw data PLUS results from all intermediate calculations - I will not submit any further papers to RMS journals.
