New maps show the risk of sea level rises to Australian cities

[News.com] SAY sayonara to Sydney airport, farewell to Fremantle and bye to Byron Bay.
A series of maps has graphically illustrated how Australia could be affected by climate change and rising sea levels. And it looks like many of our major towns and cities could be getting a lot soggier.
Hobart Airport would be underwater, Melbourne’s Southbank submerged and the WACA in Perth would be inundated.
Famous sea side resorts like Byron Bay, Port Douglas, Noosa and the Gold Coast are in danger of seeing the sea get a whole lot closer for comfort.
A climate expert has said rising sea levels globally could displace “tens of millions of people”.
The new maps come from Costal Risk Australia run by Western Australia business management consultants NGIS. The data is fished from the US’s National Oceanic and Atmospheric Administration NOAA to show which areas will be at risk from a “business as usual” scenario of a 2 metre sea-level rise by 2100.
Just by putting in your suburb name into the Coastal Risk Australia, you can see if you area is at risk of flooding.
Website co-creator Nathan Eaton said that with more than 80 per cent of Australians living near the coast, it was critical for people to appreciate what rising sea levels in the decades to come could mean for their communities.
However, in some areas its likely even a 2 metre sea rise will be surpassed. Climate scientists have pointed to parts of northern and Western Australia where rises could be higher.
The Torres Strait Islands have experienced regular king tides, an area which rarely got any of the monster tides in the past.
Professor John Church from the University of NSW’S Climate Change Research Centre said flooding to the measure forecast would cause catastrophic problems for many Australians. Read More
