Briefing note 13: How might Australia contribute to a next-generation global climate modelling facility?

May 19, 2021 11:57 am Published by Comments Off on Briefing note 13: How might Australia contribute to a next-generation global climate modelling facility?

The Royal Society has called for an international next-generation climate modelling centre (pdf), based on new cutting-edge high-performance computing and data services to support efforts toward net-zero emissions and to enable effective climate adaptation.

Briefing note 12: How sensitive is the Earth’s temperature to the amount of carbon dioxide in the atmosphere?

November 19, 2020 1:52 pm Published by Comments Off on Briefing note 12: How sensitive is the Earth’s temperature to the amount of carbon dioxide in the atmosphere?

A landmark new international review of climate sensitivity led by ARC Centre of Excellence for Climate Extremes researcher Prof Steven Sherwood has reduced the uncertainty in Equilibrium Climate Sensitivity. Estimates of likely values now vary by less than a factor of two. The new assessment concludes that the climate is more sensitive to atmospheric carbon dioxide than some previous estimates.

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”.

Briefing note 008: Global crop yields are strongly affected by extreme climate conditions

August 14, 2019 11:39 am Published by Comments Off on Briefing note 008: Global crop yields are strongly affected by extreme climate conditions

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.

Briefing Note 004: Future weather and climate extreme events

February 13, 2019 3:40 pm Published by Comments Off on Briefing Note 004: Future weather and climate extreme events

Weather and climate extremes occur on a wide range of time and space scales. Weather extremes occur on shorter timescales and are regionally or locally specific while climate extremes tend to be on longer timescales and can impact a region through to the whole globe. This note provides a statement on what we know about how weather and climate extremes might change in the future.
