Some models for climate change, the good the bad and the ugly
Modelling climate presents huge challenges for mathematicians and scientists, and has a large effect on policy makers. Climate models themselves vary from simple to complex with a huge range in between. But how good and/or reliable are they?
In this talk I will describe some of the various mathematical models of climate that are both used to understand past climate and also to predict future climate. I will also try to show that an understanding of non-smooth effects in dynamical systems can give us useful insights into the behaviour and analysis of these models.
