UEA have issued a press release noting that they have received an apology from the BBC. The kerfuffle was over a Today programme piece back in December 2009, in which John Humphrys said:
The facts are that the emails were stolen and they revealed that some researchers in the university's Climatic Research Unit had been distorting the debate about global warming to make the threat seem even more serious than they believed it to be.
The BBC explain that they were open minded on the question of whether data was manipulated and that this doubt over the guilt or innocence of the CRU scientists at the time would have been clear from the rest of the programme. So I think the BBC is probably right to apologise in this instance, since when serious claims are made it is right that they don't appear to have prejudged any investigation.
Of course, now that Muir Russell has pronounced Mike's Nature Trick as "misleading", we know that Humphrys was right all along, but that's another question.
