Dr Penny Whetton is a Senior Principal Research Scientist in the Climate Projections Science Team at CSIRO Marine and Atmospheric Research. She leads the Better Scenarios project in the Climate Adaptation Flagship. Dr Whetton is currently a lead author of the Australasia chapter of the Working Group II component of the forthcoming IPCC Fifth Assessment Report. She was also a lead author of the regionalisation and climate scenarios chapters of the Working Group I Third Assessment Report of IPCC and lead author of the regional projections chapter of Working Group I component of the Fourth Assessment Report. A major component of Dr Whetton's research is analysing the regional output of enhanced greenhouse general circulation model (GCM) experiments, and using this information to construct regional scenarios of future climate change for use in impact and adaptation assessment. She also works on regional climate change impact assessment. She has been the main contributor to, and editor of, the CSIRO's Australian climate change projections released in 1992, 1996, 2001 and the projections released by CSIRO and the Bureau of Meteorology in 2007. Dr Whetton is leading work on development of new climate change projections for Australia’s natural resource management regions, which are due for release in 2015.
