It is amazing to what length's Briffa went in order to conceal his data. Even when he was backed into a corner it still took over a year and extraordinary efforts by McIntyre to pull the data because Briffa had not meta tagged it (similar to a document dump in response to a subpoena).
This could be a major development if it can just get some MSM legs. Fox News, where are you!
IIRC the only reason Briffa had to disclose the data was that he had submitted to the Royal Society, who I understand strictly require submitters to enter their data to an archive that RS control.
Now the Royal Society have been hopelessly pro-AGW to date, but in this case their rules have allowed the truth to come out.
