About the projections

Guiding principles

Read about the guiding principles that were used to research and create climate change projections for Australia’s NRM regions. This includes why projections are not predictions and why information is presented as ranges of change.

New generation modelling

A new generation of global climate models (GCMs) has been developed by various groups around the world, and simulations from these models has been used to examine the future climate of Australia under several future scenarios. Read more about latest model experiments .


Read about the approach taken to generate future climate projections for Australia. Read about how various lines of evidence and modelling techniques are used to generate projections of future climate. Find details about how fine scale modelling approaches are used and how model evaluation is used to assess confidence and refine projections. The variables for which projections are available are also described in data availability .

What is in Climate Change in Australia?

This website contains numerous places to retrieve climate change projections information for Australia. The projections are spatially focused around natural resource management 'clusters' for which summary information is available. Also available is a range of model output (to registered users) including climate model data formulated specifically for use in further studies or applications.

Exploring climate change projection information for Australia is easy on this site. A number of ‘dashboards’ are available that allow the user to explore the projections through looking at maps of change and graphical descriptions of change . A full list of the available climate data exploration dashboards is available here .

Climate Futures web tool

The Climate Futures Tool supports users of climate projections data to select model output for specific applications.

Climate Analogues

The Climate Analogues tool is used to explore what the future climate would be like in selected cities and towns around Australia. Future climate is described as the current climate of another town or city that is in another location (focussing on temperature and rainfall).

Coastal and Marine

Coasts and marine ecosystems are important for Australia. Seven of the eight NRM clusters have coastlines. The Marine Explorer tool allows users to read about and explore projections for the coastal and marine environments including sea level rise, future sea surface temperatures, aragonite saturation and pH.
