"Extreme temperature and rainfall events are increasing around the world,
including Australia. What makes them extreme is their rarity and severity
compared to the typical climate.

A region’s “climate” is defined by a 30-year average of mainly rainfall and
temperature. Increasingly, these climate definitions have become less
appropriate – we need to look at events over shorter time periods to gain a
more accurate picture.

We can see this in the recent worldwide proliferation of extreme flooding and
prolonged heatwaves.

Using southern Australia as a prime example, our newly published research in
Academia Environmental Sciences and Sustainability shows that machine
learning techniques can help identify key climate drivers, supporting a
redefinition of climate in a warming world."
