A relatively junior climate scientist, at least compared to those who usually act as public voices for the profession, Edwards is making a name for herself as a prolific and fearless communicator, especially online. Currently a research associate at the University of Bristol exploring uncertainty in earth system modelling, Edwards initially trained in high energy physics. Happy to argue about power and the patriarchy along with the science, she is respected by many sceptics for the time she devotes to engagement with their communities. Although she’s had her fair share of battles with other scientists, especially on issues of advocacy, it is fair to say she is highly respected by this community too, as well environmentalists. You can follow her on Twitter @flimsin and read her blog – All Models are Wrong – hosted by the Public Library of Science.
