The Canadian Radio Network, CBC, has run a radio series, titled "Climate Wars" with IISS friend Gwynne Dyer as the host. I've only stumbled across this today, and am only through the first episode of the series. So far, I can attest that its a very strong and interesting program. He was able to get very strong interviews that read as a 'who's who' of imporant players in the climate security argument, including John Holdren and others.
I can't link directly to the radio program, but you can listen to it through the CBC's website, here.
