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

May 2, 2022 1:59 pm Published by Comments Off on 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.

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 11: Research on the Antarctic stratospheric polar vortex is important for Australia’s seasonal forecasts

April 7, 2020 2:51 pm Published by Comments Off on Briefing note 11: Research on the Antarctic stratospheric polar vortex is important for Australia’s seasonal forecasts

Research has established a link between Antarctic stratospheric winds and an increased risk of weather conducive to bushfires from late spring to early summer. Further research on the relationship between winds and ozone in the Antarctic stratosphere could improve seasonal forecasts for Australia.

Briefing note 10: Research on heatwaves and droughts by the ARC Centre of Excellence for Climate Extremes supports a major international report on Climate Change and Land

December 11, 2019 11:11 am Published by Comments Off on Briefing note 10: Research on heatwaves and droughts by the ARC Centre of Excellence for Climate Extremes supports a major international report on Climate Change and Land

This research brief examines how research from the ARC Centre of Excellence for Climate Extremes informed the IPCC Special Report on Climate Change and Land.

Briefing note 009: Does global warming cause droughts, drying or increased aridity?

September 20, 2019 3:06 pm Published by Comments Off on Briefing note 009: Does global warming cause droughts, drying or increased aridity?

In an hour-long talk to a business forum, Andy Pitman said: “there is no link between climate change and drought”. Given the audience were not climate scientists, or interested in the physics of the climate, this statement was one word too brief. Andy fully admits he should have said: “there is no direct link between climate change and drought”.
