Tamsin Edwards is a Lecturer in Physical Geography at King's College London. Her research looks at how we confident we are in predictions from climate models about the range of possible futures we might face. She is particularly interested in how Greenland and Antarctica are responding to global warming and what that means for sea level rise. Tamsin talks about climate science to the public a lot, of which probably the most terrifying were a TEDx talk at CERN and a live debate on Newsnight. She blogs at "All Models Are Wrong" [http://blogs.plos.org/models] and on Twitter she is @flimsin [http://twitter.com/flimsin].
