Tamsin Edwards is a particle physicist turned climate scientist trying to find out how uncertain we are about climate change – from the last ice age to future sea level – and how best to communicate this. She is an active blogger and uses social media to change the way people think about climate science. Edwards was named one of "20 women making waves in the climate change debate". A postdoctoral researcher at the University of Bristol, she is preparing to begin a lectureship at the Open University, using multidisciplinary research and communication to provide distance learning in environmental sciences.
