Atmospheric rivers in Australia

We are conducting research to determine if we can forecast changes in the probability of extreme rainfall events associated with atmospheric rivers 2-6 weeks ahead.

Understanding Australia’s rainfall

June 8, 2022 3:41 pm Published by Comments Off on Understanding Australia’s rainfall

By bringing together researchers focussed on the large-scale modes of climate variability with researchers investigating weather and land surface processes, our goal is to improve the regional predictions of how rainfall extremes will change in the future.

A new global picture of compounding weather and climate hazards

The difference in results between the high-skill and low-skill CMIP6 models highlights an urgent need to examine why some models work well and some don’t, and, ultimately, improve those with weaknesses.

Climate change and tipping points

March 7, 2022 4:20 pm Published by Comments Off on Climate change and tipping points

Tipping points exist in the climate system, and it is very unlikely that all tipping points are known. Different tipping points are understood with different levels of confidence, they operate on different timescales, can interact to trigger cascades of abrupt changes, and some tipping point changes are irreversible on timescales of centuries to millennia.

Briefing note 17: Could understanding the Indian Ocean improve climate predictions for Australia?

You may have heard about the influence of sea surface temperatures (SSTs) in the tropical Pacific Ocean on Australia’s climate and how forecasts of the El Niño–Southern Oscillation (ENSO) help to give warnings of flood, drought and bushfire risk in Australia months in advance… but what about the tropical Indian Ocean?

IPCC AR6 Working Group 1 report: conclusions on the evolving risk of drought

September 7, 2021 3:58 pm Published by Comments Off on IPCC AR6 Working Group 1 report: conclusions on the evolving risk of drought

Drought is a major risk to Australia with extended periods of drought affecting our social, economic and environmental systems. The newly released report by the Intergovernmental Panel on Climate Change contains significant new assessments of the science and future projections of drought.

Briefing note 16: What is left in the global carbon budget?

August 25, 2021 3:37 pm Published by Comments Off on Briefing note 16: What is left in the global carbon budget?

The Paris Agreement requires countries to commit to reducing their greenhouse gas emissions to ensure that the global average temperature remains well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C. But how likely are we to meet these targets?

Briefing note 15: Can we limit global warming to 1.5C°?

July 28, 2021 2:43 pm Published by Comments Off on Briefing note 15: Can we limit global warming to 1.5C°?

Irrespective of tipping points, climate change adaptation efforts will be less costly and disruptive to society – and will stand a better chance of success – if warming can be limited to 1.5°C rather than 2°C or higher. We therefore in no way advocate for policies that forgo pursuing the ambition to limit global warming to 1.5°C, regardless of whether that target remains feasible or not.
