Climate models are the best tools currently available for understanding our future climate. They are vital for understanding how the components of the climate system –the oceans, atmosphere, snow and ice and land –interact and change due to both natural variability and human-influences. They are also invaluable tools for understanding climate processes, such as coupled ocean-atmosphere climate modes, including El Niño-Southern Oscillation.

Australia has therefore developed our own national weather, climate and Earth system model -the Australian Community Climate and Earth System Simulator (ACCESS). ACCESS has been developed over the past 15 years by researchers across leading Australian climate research agencies, such as the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the Bureau of Meteorology (BoM), the Australian Research Council (ARC) Centres of Excellence for Climate System Science and then for Climate Extremes and multiple Australian universities in collaboration with international research institutes. The development of ACCESS has been supported through programs such as the Australian Climate Change Science Program, the National Environmental Science Program (NESP) and the National Collaborative Research Infrastructure Scheme (NCRIS).
