The United Nations has made the call: ‘Restricting temperature rise to 1.5 degrees is unachievable’, which effectively gives eviction notices to Byron Bay, Bruns, Ocean Shores etc, as they are developed at a lower height than the approximately three-metre increase in sea level associated with the now accepted as unavoidable 1.5 degree temperature rise.
Mullum town, and housing on the periphery, will also go permanently under water as the river height increases in step with ocean height rises.
Everybody, in largely coastal properties, which are less than approximately three metres above sea level, will unavoidably need to move as the sea reclaims this land.
We will also be faced with increasing times of lower food production and transport problems with inevitably increasing extremes of droughts, floods, and cyclones.
Present Council planning considerations, which are limited to near-future timeframes, don’t provide a robust system anymore.
There needs to be additional longer-term planning for Australia’s developed coast retreating inland. Perhaps the powers-to-be will respond when they accept that all Sydney’s beaches and adjacent development, and the Sydney Harbour mansions, will inevitably be under the sea. Or perhaps we should look at addressing the impacts outside of these organisations that have demonstrated incompetence.
