Tamsin Edwards moved into climate science in 2006. Her research interests are in quantifying uncertainty in predictions from earth system models. When modelling climate, or the behaviour of ice sheets and glaciers, Tamsin says “we cannot test our predictions by performing repeated experiments on the earth system. I am particularly interested in Bayesian approaches to this problem – in which probability is a degree of ‘belief’ based on current information, rather than an observed frequency – and collaborate whenever possible with Jonty Rougier.”
Tamsin is working on the EU Framework-7 programme ice2sea, which aims to improve projections of the contribution of ice to future sea level. This is a comprehensive collaborative effort to improve understanding of this research area. Tamsin’s work has included statistical analysis of climate and ice sheet model simulations, and experimental design, for several topics: a probabilistic prediction of the Antarctic contribution to future sea level, a new assessment of the feedback between surface mass balance and ice sheet surface height in Greenland, a new assessment of the effect of meltwater on glacier sliding (basal lubrication) in Greenland, and comparisons between multiple ice sheet models.
