Coastal Risk Australia
NGIS and FrontierSI have updated Coastal Risk Australia to reflect the latest IPCC report.
Coastal Risk Australia communicates the latest scientific modelling to allow the public to simply and easily visualise how rising sea levels may encroach on their community. It aims to place scientific modelling into the hands of the people so they can see for themselves how the areas they live in could be impacted in the future by climate change.
The advances in science confirmed in the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment report show that sea levels will continue to rise for future generations, impacting on Australia’s coastal infrastructure, and coastalrisk.com.au communicates how the new projections impact Australian coastal communities.
The new scenarios are based on the new climate change report from the IPCC which incorporates significant advancements in modelling the behaviour of ice sheets. The scenarios shown depict the high emissions scenario (indicating that by 2100 global sea levels could have increased by 0.84m), as well as the potential worst case scenarios based on very high emissions (unlikely) of a 2m sea level rise by 2100 and 5m sea level rise by 2150.
IPCC modelling has shown with high confidence that sea level will rise for centuries due to continuing deep ocean warming and ice sheet melt, and will remain elevated for thousands of years. Over the next 2000 years, global mean sea level will rise by about 2 to 6m if limited to 2°C of warming, and 19 to 22m with 5°C of warming, and it will continue to rise over subsequent millennia.
