Zebedee Nicholls is a Research Fellow at Melbourne Climate Futures, The University of Melbourne and The International Institute for Applied Systems Analysis (IIASA). His research focuses on the development, evaluation and application of reduced complexity models with a particular focus on the Model for the Assessment of Greenhouse gas Induced Climate Change (MAGICC). Alongside A/Prof Malte Meinshausen, he leads the Reduced Complexity Model Intercomparison Project (RCMIP). To facilitate this work and enhance reproducibility, he is committed to developing open-source scientific software and contributes to a number of projects (see github.com/znicholls and gitlab.com/znicholls). In the IPCC’s Sixth Assessment Report, he led the writing of Cross-Chapter Box 7.1 on reduced complexity models used for scenario classification in AR6, was a Contributing Author to WG1 Chapters 1, 4, 5, 6, 7 and Technical Summary and WG3 Chapter 3 and Annex C. He is currently working on the next phase of RCMIP, taking MAGICC open source and developing more regionally detailed emulators.
