This lecture by Mike Hulme is interesting, if slightly drawn out. It is also frustrating not being able to see the slides. I liked the bit where he recalls rediscovering his former activism in support of the Kyoto protocol through reading the Climategate emails.
As he lists all the damage done by global warming activism, it's hard to avoid a certain feeling that the taxpayer would be better off without funding all these people paid to research climate change and promote "solutions".
