Roger Harrabin emails to ask if I know any UK-based physical scientists who are sceptics. Not many is the answer, but then I don't know who the vast majority of my readers are anyway.
I do serve a lot of pages to readers at .ac.uk web domains, and I can see that at least some of these are from physical science departments, so it's fair to say that such people exist, although they are perhaps few in number. If so, Roger H would like to hear from you, in confidence, if necessary. He also welcomes evidence that putting one's head above the parapet in this way is a career-ending move.
Commenters have already noted Paul Dennis's remarks at WUWT to the effect that he responded to Roger H's earlier call and didn't get any reply worth the mentioning, but I would suggest that this could reasonably be interpreted as an oversight. Best to make the effort I would say.
