Last night’s session with the Skeptics in the Pub in Christchurch was an interesting experience (some nice feedback too, thanks). It gave me a chance to develop a few of the thoughts that have been running through my mind recently — and it’s good to do that by presenting them to an audience willing to explore and challenge ideas. The question session at the end ran for about 40 minutes, and the best moment came when one sceptic (no “k”, he was clearly of the “not persuaded” variety) had been pushing me for a worst case. I said that it was conceivable that climate change could end our civilisation. The questioner turned to the rest of the audience and asked them if they really believed that, to receive a chorus of agreement and nods. That’s what happens in the real world: when sceptics leave the comfortable certainty of Wishart-world or Treadgold territory, µWatts or Morano’s depot, they find that the rational world is coming to terms with the real risks.
I promised the group I would make my slides available: they’re here [3.3MB pdf]. The first half of the talk dealt with some basics, and ended with a Katey Walter earth fart lighting session. I then moved on to explore some of the reasons why there is so much manufactured doubt about the reality or seriousness of climate change. The slides are reasonably self-explanatory, happy to discuss in comments.
