Flooding in New South Wales and southeast Queensland has led to lost lives, homes, belongings, pets and livelihoods. Thousands of people in south-western Sydney have been ordered to evacuate as extreme rain pummels the region and floodwaters rise rapidly. The devastating floods have also cut off power for tens of thousands of people across New South Wales and Queensland, limiting their access to basic amenities and hampering rescue efforts.

This region, particularly Western Sydney, is no stranger to climate-related disasters.

 

Around 2,000 homeowners in flood-prone areas of the Northern Rivers of New South Wales will now be eligible to raise, repair, retrofit or have their home voluntarily bought back, as part of a A$800 million government program.

More than three months after the monster floods wrecked much of Lismore, there is still no clarity for the town’s residents and businesses who urgently need to make investment decisions. Should they move to higher ground, make temporary fixes, renovate?

To understand how extreme weather like this year’s Southern Hemisphere deluges will change as the climate warms, we must understand the underlying physical processes responsible for their development.

While local and state governments have led the way on climate adaptation to date, citizens have much more to do, as the worrying lack of preparation for the floods that devastated Lismore makes clear.
