Also published at Skeptical Science This is a climate model: T = [(1-α)S/(4εσ)]1/4 (T is temperature, α is the albedo, S is the incoming solar radiation, ε is the emissivity, and σ is the Stefan-Boltzmann constant) An extremely simplified climate model, that is. It’s one line long, and is at the heart of every computer [...]

Today’s edition of Nature included an alarming paper, indicating record ozone loss in the Arctic due to an unusually long period of cold temperatures in the lower stratosphere. On the same day, coverage of the story by the Canadian Press included a fundamental error that is already contributing to public confusion about the reality of [...]

This is what the last few days have taught me: even if the code for climate models can seem dense and confusing, the output is absolutely amazing. Late yesterday I discovered a page of plots and animations from the Canadian Centre for Climate Modelling and Analysis. The most recent coupled global model represented on that [...]
