We all know climate change makes extreme weather more likely. But it’s also loading the dice for quick-forming drought, sudden and intense rainfall and fast-forming tropical storms.
Forecasters warned of ‘potentially historic rainfall’ and ‘dangerous to locally catastrophic flooding.’ A hurricane scientist explains what El Niño, a heat dome and mountains have to do with the risk.

As someone who lost pretty much everything in the 2011 Brisbane floods and then led a study on community responses to those floods, I have some insights on what helps – and what doesn’t.
Urban gardens, parks and green walls are crucial ways to tackle flash floods and city heat. But new global research finds its effectiveness varies from city to city.
