I use climate models, observations and palaeoclimate records to provide a long-term perspective on recent climate change. I have a particular focus on recent extreme rainfall and temperature events in Australia. My work also involves proxy-model comparisons to understand natural and anthropogenic influence on climate.

Climate change and East African rainfall: combining observations from local farmers and weather stations

Project

Climate change is already affecting weather patterns in many locations. In East Africa, changing rainfall would challenge the livelihoods of farmers. However, perceptions of local farmers and data from local weather stations differ. Is rainfall changing? How can we understand these two important information sources? In this project, you will re-analyse meteorological rainfall data, using an analysis approach based on metrics more familiar to farmers. This project will provide useful information for the 80% of Ethiopians living in rural areas, who are reliant on rainfall for their livelihoods. This project would ideally suit a student with some experience of/ or interest in developing skills in programming for example with MATLAB, R or excel, under guidance and supervision. Successful applicants will be provided with a weekly allowance at a rate of $500 (tax exempt) per week, up to a total amount of $5000 for the duration of a 10-week scholarship
