Images - Climate change, models, focussing on feedback. Some of the more pressing and worrying images of our time concern climate change, and what the future holds. Since I wrote that we now have Covid-19, so no apocalyptic image of climate change is needed here. But the reactions of at least some nations are clearly in response to models. How people react to predictive models has acquired added significance. I hope you are al keeping safe and hope to reach you again on the other side of all this – whatever that looks like. However, it seems likely that a critical and informed appreciation of modelling is only going to become more important.
