Judith Curry is fast becoming the go-to scientist favoured by the more sceptical ends of the climate debate, though she is more than capable of making a name for herself in her own right. An established climate scientist, well known for her research on hurricanes and Arctic ice, Curry is currently Chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. Troubled by the way those who do not fit with scientific consensus are treated by the scientific community and broader environmental discourse she regularly speaks up for the role of dissent and free speech in climate science. It is fair to say this doesn’t always win her friends in either science or the green movement. Curry is an active blogger, reflecting her commitment to transparency of the debate within science, and can be found on Twitter @curryja.
