Channel Four news here in the UK has just reported the Philip Campbell has stepped down from Sir Muir Russell's review because of the statements to Chinese radio that were reported here. This was undoubtedly the correct thing for him to do.
There was some discussion on the Channel Four report of sceptics seeing his departure as "taking a scalp" - I don't see this as being the case. The panel needs to be unbiased, without predetermined positions on the issue of climate change or climate science - these are, in essence, Sir Muir's words. Campbell clearly didn't meet this requirement and his resignation therefore became inevitable.
A replacement will obviously have to be found, and I am going to make some suggestions to Sir Muir as to where such a person might be found. In the meantime we still have the issue of Geoffrey Boulton, the ex-UEA man who has spoken out strongly in the past in favour of the global warming position. Although he's not as wildly inappropriate as Philip Campbell his position on the panel still makes it look somewhat unbalanced. I would suggest that either he needs to go too or he needs to be balanced with somebody of sceptical views.
