In 2007 the Intergovernmental Panel on Climate Change (IPCC) released their fourth assessment report, concluding that:
- Warming of the climate system is unequivocal
- Humans are very likely to be causing most of the warming that has been experienced since 1950
- It is very likely that changes in the global climate system will continue well into the future, and that they will be larger than those seen in the recent past.
These changes have the potential to have a major impact on human and natural systems throughout the world including Australia.
The IPCC reports provide limited detail on Australian climate change, particularly when it comes to regional climate change projections. For this reason the Australian Greenhouse Office, through the Australian Climate Change Science Programme, engaged CSIRO and the Bureau of Meteorology to develop climate change projections for Australia.
