Out here on the Thames Delta, we are entering a one-day freak heatwave – something like 12 Celsius higher than yesterday, hitting 32C, dropping by 11 Celsius tomorrow. Yes, there are places in the world where 32C is nothing, but, ahem, this is England. Going from a pleasant 20C to 32C overnight is A Thing here. And this office is a hotbox at the best of times. So I’m shutting down as many machines as possible and going to the notebook.
