Projections
Future climate changes
Scientists are confident that human induced climate change will continue. In Australia, average temperature increases of 0.4 to 2.0°C are likely by 2030 together with changes in rainfall patterns and the frequency and/or intensity of extreme weather events such as drought and severe storms. This section presents information about projected changes in Australia's climate, including projections for climate change in different parts of the country.
How projections are done
Scientists use sophisticated numerical models to project future climate. Find out what the models do, their limitations and the assumptions about future greenhouse gas emissions built into the projections.

The Australian Government is working with CSIRO and the Bureau of Meteorology to model future climate change scenarios.
Regional climate projections
New climate projections for Australia have been prepared for the Australian Climate Change Science Programme by CSIRO and the Bureau of Meteorology. The projections confirm that Australia will get hotter and is likely to become dryer in the south. They include information on likely changes in tropical cyclones, large hail, fire weather and drought frequency as well as the probability of change in temperature and rainfall rather than simple ranges of possible change.
Climate change scenarios
These simplified climate change scenarios are designed for use in risk management. They focus on a narrow range of possible futures for ten broad regions rather than capturing the full range of possible climate change detailed in the regional climate projections.
