Looking at his 'application' form, he doesn't have that many real references. He looks to be retired. Being an editor on Climate Research is something I wouldn't put on my CV. It is a discredited journal in the field. Most of the people he puts in the email (the 4 in the US and the other 5 are mainly greenhouse skeptics - although Changnon, Landsea and Pielke are mainstream climatologists). So, I'd be wary of accepting him as a fellow.
