For each State and the Northern Territory (see navigation bar above) we are  presenting maps showing impacts around Australia of sea level rise predicted for this century.  Maps have been generated from  Coastal Risk Australia's site which uses Google Earth Engine .

A first set of maps showed inundation levels at high tide based on a 0.74 metre sea level rise. In the Fifth International Panel on Climate Change Assessment Report (2013/14) this was regarded as a high end scenario for 2100.

The sixth IPCC Assessment Report indicates 0.84 metres sea level rise. Coastal Risk Australia's maps have been updated to reflect high tide impacts for this scenario, which in some locations are significantly worse. We are progressively updating maps on our own site to reflect this during January 2022.

These maps make shockingly clear one major aspect of what Australia has to lose from sea level rise, and how important it is both to take serious action to minimise the amount of human-caused climate change, and to take seriously the need to adapt to the climate change we are unable to avoid. 

If you need a larger version of any image just go to Coastal Risk Australia and type in the location to the search box. Note the disclaimers on the site: these are predictions; reality may well prove worse without rapid serious climate action.
