Climategate scientist [Phil Jones] breaks his silence - environment - 28 July 2010 - New Scientist

[Q] Climategate has highlighted conflicts between climate scientists and some of their critics. Is there a value in having critical voices contribute to scientific discussions?

PJ Yes, provided they do it through the normal processes, which is through peer review. I say that not because there's no value in the blog sites, but because it's necessary. Unless the alternative views are in the peer-reviewed literature, the Intergovernmental Panel on Climate Change cannot refer to them.

PJ I don't hold a world view - that's ridiculous. I have no interest in policy at all. I'm interested in the science, not the policy. I get these emails saying I'm trying to change the world government - it's just ridiculous. People assume that I'm advocating that society should be doing certain things. I'm not. We try to be totally apolitical in the CRU.

...There should be an acceptance that the climate has warmed since measurements began. OK, there's then debate about what caused that warming. But I do find it difficult engaging with people who deny the evidence and say the world has not warmed.
