Climate predictions provide key scientific input into climate policy – and will continue to do so in future years. Professor Tim Palmer, Co-Director of the Programme on Modelling and Predicting Climate, will discuss how scientific and technical advances can be expected to improve our climate predictive capability in the coming years – for example through the application of inexact supercomputers, about which James Martin himself was especially enthusiastic. With projects like the Large Hadron Collider in mind, Tim will also discuss possible changes in the way climate prediction science organises itself internationally. Finally, Tim will address the important question of how to attract more mathematicians and theoretical physicists into the field of climate science.
