Just came across what seems to be an excellent TEDx talk, by Steve Easterbrook, about climate models. One take away message seems to be that climate models are less buggy than virtually all commercially available software, and they’re almost as good as that developed for the space programme. What was also interesting was the comparison – at about 8 minutes – between a year’s worth of weather from a climate model, and a year’s worth of satellite data. Fascinating; I’d never seen such a comparison before. Also included an amusing illustration of the difference between forecasting weather – which we can only do, accurately, for a about a week or so – and climate modelling – which is really about patterns and trends, rather than specifics.
Anyway, there was much more to the talk than just that, but you’ll have to watch it to find out more 🙂
