Sarah’s work focuses on Australian climate extremes. Her work explores observed trends in droughts and heat waves and estimating the uncertainty associated with observations. Sarah is also working on determining the natural and human components of observed regional climate change in Australia, using both observed and climate model data. She will also investigate the combined affects of natural variability and increased greenhouse forcings on changes in climate extremes throughout the 21st Century. Dr Perkins has developed a website, Scorcher, that allows members of the public to look back over the size and intensity of Australian heatwaves. You can also read the following article about the website in The Conversation: It's a scorcher: new site tracks heatwaves across Australia (December 19, 2013). You can find out more about Sarah at her website, Sarah in Science. ( )
