Extreme events

Bushfires and heatwaves will be more common

There is a strong interest in understanding the changing odds of extreme weather events as the underlying climate system changes. Scientists have examined extreme weather events of 2014 to see if they can be attributed to climate change.

A team looking at the effect of a warming climate on the frequency and severity of La Niña events has found they are likely to be twice as frequent in future.

The latest round of bushfires, which claimed 27 homes in the Adelaide Hills, has once again highlighted the importance of planning for the worst. Mercifully, no human lives were lost, and it will be important to learn whatever lessons we can to avoid future tragedies.
