Two years ago I took part in the World Peace Summit: Climate Change — What To Do? in Wellington, at the Westpac St James Theatre. I blogged about it at the time (before and after), and promised to link to the video of my talk when it was available. Of course, I then completely forgot to check, and so when I stumbled upon myself on Youtube earlier today, I thought I’d finally keep my promise. Given that I was talking in 2008, I think my comments stand up quite well (I’m rather pleased with my remarks about warmer winters being snowier winters), though my technological optimism is now tempered by pessimism both about the state of the climate system and our ability to come up with policies to reduce emissions. If you follow the “more from” links on the Youtube page, you can also watch David Wratt, Pene Lefale, Rod Oram, Andrew West, and Rachel Brown’s presentations.
