Climategate: Mann now turns on Jones

One of the scientists to whom the emails were addressed, Professor Michael Mann, the Director of the Earth System Science Center at Pennsylvania State University has moved to distance himself from some of the comments in the emails that suggest scientists did not want the IPCC, the UN body charged with monitoring climate change, to consider studies that challenged the view global warming was genuine and man-made.

Speaking to BBC Radio 4’s The World Tonight, Prof Mann said: “I can’t put myself in the mind of the person who wrote that email and sent it. I in no way endorse what was in that email.”

Prof Mann also said he could not “justify” a request from Prof Jones that he should delete some of his own emails to prevent them from being seen by outsiders.

“I can’t justify the action, I can only speculate that he was feeling so under attack that he made some poor decisions frankly and I think that’s clear.”

Prof Mann then argued however that there was “absolutely no evidence” that he too had manipulated data, while he also said “I don’t believe that any of my colleagues have done that”.
