PPS I have had a chance to listen to the video, and in particular to the question and answer session of the final 30 minutes or so. Here are my comments on that, as posted on Bishop Hill (on the post linked to in the PS hat-tip):
'The core alarmist proponents only comprise a few dozen, mostly third-rate, academics whose scientific reputations are minimal outside of climate alarmism. They co-opted the niche, little known interdisciplinary field of climatology, proclaimed themselves to be the world authorities, declared a global crisis, received lavish funding to research it and gained global attention. They have been aided and abetted by sundry fellow travelers who see advantage for various other agendas.'
