What Will The Australian Coastline Look Like in 2100?

How will sea level rise affect your local area over the next decades? Here is an Australia-wide map, Coastal Risk Australia 2100, you can search to see the impact of three scenarios of sea level rise by 2100. 

Inundation Scenarios 

The scenarios here are based on findings from the Intergovernmental Panel on Climate Change.
  • The low scenario = .44 m by 2100. This considers sea level rise in the context of a global agreement which would bring about dramatic reductions in global emissions.  
  • The medium scenario = 0.54 metres by 2100. This scenario considers sea level rise where global emissions stabilise after 2100. 
  • The high scenario = .74 metres by 2100. This scenario is in line with recent global emissions and sea level rise observations.

This is a Beta model - still in development and open for comment, but certainly worth a look.

Already there are climate change refugees globally. Land and life in many small Pacific islands are being affected. Here's a short film describing some of the impacts in Tuvalu to the north east of Australia.
