Ballina to be completely submerged by 2100
BALLINA will be completely underwater by 2100 according to new modelling released today.
The Coastal Risk Australia website has combined Google's mapping technology with local tidal data to accurately map how rising sea levels could encroach on cities, towns and beaches under three scientific scenarios.
Based on its predicted sea levels on a high tide in 2100, the island of Ballina and other parts of the Lower Richmond River are underwater.
Other victims of the global sea level rise Byron Bay, which will be virtually cut off except for a narrow finger of land through Suffolk Park, much of the Lower Richmond, and parts of Evans Head.

Nearby regions including low-lying parts of the Gold Coast and the Sunshine Coast are also set to go under.
In a statement released by NGIS Australia who developed the app, "more than 80 percent of Australians live near the coast and a Climate Council report has already warned that future sea level rises could put more than $200 billion of infrastructure at risk".
NGIS Australia principal consultant Nathan Eaton said it was difficult for people to appreciate what rising sea levels in decades to come could mean for their homes, community and the places they love.
"Maps are a universal language that everyone can understand.
"This website allows every Australian to visualise our climate change future with pinpoint accuracy, and gain a better understanding of how rising sea levels will affect our coastline, neighbourhoods and favourite places."
"Our main goal is to raise awareness of how sea-level rise will effect the places we live, but this will also help all Australians prepare for change, from all levels of government, in policy, conservation and community engagement."
Scientists are forecasting sea levels will rise between 0.4-1.1m over the remainder of this century depending on how rapidly the world reduces emissions of greenhouse gases.
The frequency of coastal flooding trebles with every 10cm of sea-level rise. In both Fremantle and Sydney, flooding events became three times more frequent during the 20th century as a result of sea-level rise.
