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.
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 Extremes is leading research that will ultimately help businesses and governments better assess the risks posed by compound events.
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.
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.
Research on the Antarctic stratospheric polar vortex is important for Australia’s seasonal forecastsApril 7, 2020 2:51 pm Comments Off on 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.
Research on heatwaves and droughts by the ARC Centre of Excellence for Climate Extremes supports a major international report on Climate Change and LandDecember 11, 2019 11:11 am Comments Off on 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.
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”.
The ARC Centre of Excellence for Climate Extremes has contributed to a new scientific study that reveals that extremely hot and cold temperatures, drought and heavy rainfall strongly affect the year-to-year variation in the total global yield of four important crops.
Large areas of northern Queensland experienced extreme rainfall and severe flooding in late January and February 2019. This briefing note examines the impacts and some of the likely causes of the event.
