Projections of Australia's future climate are available by selecting your region of interest on the map or menu to the right.

Our future climate will depend on greenhouse gas emissions, so the regional projections are available for low, mid-range and high greenhouse gas emissions scenarios. These scenarios were developed by the Intergovernmental Panel on Climate Change (IPCC), and are based on various assumptions about demographic, economic and technological factors likely to influence future emissions.

The regional projections are relative to the period 1980-1999. For convenience, the baseline is called 1990.

Projections are given for 2030, 2050 and 2070. The projections give an estimate of the average climate around these years under future greenhouse gas emission scenarios, taking into account the consistency among climate models. Individual years will, of course, show some variation from this average.

Note that not all of the uncertainty associated with projecting future global and regional climate change can be easily quantified. Changes outside the ranges given here, and particularly those beyond the upper limit of the ranges given for 2070, cannot be excluded, although the likelihood of this occurrence cannot be estimated at this stage.
