Flooding

Australia's coastal settlements are highly exposed to the impacts of climate change. Climate-resilient urban landscapes that can cope with large amounts of water need to become the new normal.

In 2017 18.8 million people were displaced by natural disasters, with floods accounting for 8.6 million. Climate change is poised to drive those numbers higher still.

A global analysis of rainfall and rivers by UNSW engineers has discovered a growing pattern of intense flooding in urban areas coupled with drier soils in rural and farming areas.

The world’s most extensive study of the impacts of coastal storm fronts in a changing climate has found that rising seas are no longer the only threat.

Thirty-year weather records from 79 locations across Australia reveal peak downpours during storms are intensifying at warmer temperatures, leading to greater flash flood risks.

Dangerous flooding in a future warmer climate may be greater than forecast because of changes to the distribution of rainfall within storms, writes Ashish Sharma and Conrad Wasko.

It's high time we learned to adapt to our land of droughts and flooding rains, rather than failing time and time again to try to make it adapt to us, writes Richard Kingsford.
