Coupled chemistry-climate models are being increasingly used to tackle the problem of understanding the mechanisms for driving changes in past, present and future atmospheric composition. Given the computational overheads of running these types of models the chemical mechanisms which are used are often chosen for their speed of simulation.
The most pressing needs in understand climate change are now on the regional and local scale. Although it is well known that global temperatures will increase in the next century, what is more poorly known is how these changes will affect populations on the local scale. Consequently there is a pressing need to bring the predictions of climate models down to scales amenable to policy makers on this level.

Joint Seminar with the Statistics and ESS Departments: Changes in Means and Extremes of Surface Temperatures, from Centennial to Daily Timescales
Characterizing how the magnitude and frequency of extreme climate events are changing, and will continue to change due to anthropogenic forcing of the climate system, is currently a major challenge for the climate sciences. While the current warming trend is certainly contributing to the recent increase in warm temperature extremes and decrease in cold extremes, far less is understood about the contribution of possible changes in the variability about the central tendency. These issues are explored on two distinct time scales.
