Professional biography

I'm Tamsin Edwards, a Lecturer in Environmental Sciences at The Open University. Before that I was a postdoctoral researcher at the University of Bristol, and before that I did a PhD in particle physics and an undergraduate physics degree at the University of Manchester.



Research interests

I'm interested in quantifying uncertainties for earth system models: in other words, how confident can we be in our predictions of climate change? Here is my publication list.

Impact and engagement

I do quite a lot of public engagement. Here is a TEDx CERN talk, and here are some news interviews including Newsnight.

Quantifying Uncertainty in ANTarctic Ice Sheet instability

Large parts of the Antarctic ice sheet lie on bedrock below sea level and may be vulnerable to a positive feedback known as Marine Ice Sheet Instability (MISI), a self-sustaining retreat of the grounding line triggered by oceanic or atmospheric changes. There is growing evidence MISI may be underway throughout the Amundsen Sea Embayment (ASE) of West Antarctica. If this is sustained the region could contribute up to 1-2 m to global mean sea level, and if triggered in other areas the potential contribution to sea level on centennial to millennial timescales could be two to three times greater. However, physically plausible projections of Antarctic MISI are challenging: numerical ice sheet models are either too low in spatial resolution to explicitly resolve grounding line processes or else too computationally expensive to assess modeling uncertainties. The proposed work brings together and analyses two new datasets that complement each other in model complexity – a large ensemble generated with a low resolution model, and a small ensemble from a high resolution model – by constructing a new emulator of the relationship between them.
