Can we believe that the climate will change in the long term, when we can’t even predict tomorrow’s weather? Our guest Tim Palmer is a Professor in Climate Physics at the University of Oxford, and President of the Royal Meteorological Society. In this interview with Professor Tim Palmer he reminds us that we are quite good at predicting the weather. He will also tell us what the job entails and how maths and physics are at the core of making predictions.

Also, a Cambridge project is seeking to improve farming practices in Africa by sharing advances in biotechnology. They’re called Biosciences for Farming in Africa.
