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.

Climate sensitivity describes how sensitive the Earth’s temperature is to a doubling of the amount of carbon dioxide in the atmosphere. One measure of climate sensitivity for projections of future climate is the Equilibrium Climate Sensitivity (ECS). ECS is the increase in the global average temperature between the pre-industrial era and a future doubled carbon dioxide climate once equilibrium of the climate has been reached.

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.

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.

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.
