Extreme events

Plants resprouting from a tree trunk after fire

We Aussies like to think we’re resilient, but knowing what that looks like at a time of unprecedented challenge takes more than national pride – it takes good science.

Dry dam with very little water

Day Zero marks the day when residential taps are turned off — a reality for some regional and rural towns across Australia. When this current drought breaks, we can’t lose sight of the fact that another drought will inevitably come. We have to prepare for water security now.

Australia’s fire season isn’t over yet, but a significant flux of greenhouse gases have already been released into the atmosphere. Our scientists have been exploring their impact.

Climate modelling increases our understanding of the impacts of climate change including risk of fire, flood and cyclones. But can we rely on climate projections to manage future risk?

Australia is in the midst of an unfolding extreme bushfire season, with far-reaching impacts for many communities across the nation, particularly in the southern and eastern areas. We wanted to check in with one of CSIRO’s senior climate researchers, Dr Michael Grose, to understand how extreme events like bushfires are linked to climate change, and where science leads to certainty in our understanding and where there are more research questions to be explored.

Sydney and New South Wales (NSW) north coast residents continue to battle poor air quality as a result of fires burning through the state. Our bushfire expert Andrew Sullivan delves beyond the smoke haze to explain the current crisis and the tough conditions ahead.

The field of climate change event attribution research has emerged recently and can provide new insights into Australian climate extremes.

A collision of severe weather events can destroy lives and infrastructure, destabilising economies and ecosystems. In a rapidly warming world the frequency and magnitude of these compound events will only increase, according to the latest report from the IPCC.

Dr Brian Walker received the Blue Planet Award in Tokyo for his work at the forefront of the interdisciplinary area of resilience of complex adaptive systems. With drought, typhoons, earthquakes and tsunamis all in our region, the award is timely.
