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.

The past four months have seen the Heatwaves and Cold Air Outbreaks research program focus very much on improving our capacity to understand and help others in research and industry get an insight into the impact of extreme heat events.
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.
PhD student Charuni Pathmeswaran was invited as a climate scientist to take part in a young professionals’ event organized by the NESP Earth Systems and Climate and Change (ESCC) Hub and jointly hosted by the Actuaries Institute and Engineers Australia.
NESP Earth Systems and Climate Change hub and CLEX have been working closely with the finance industry to assist it in understanding climate risks. The work has ranged from presentations through to catastrophe modelling for key industries.
Marine heatwaves are becoming longer and more frequent. A global assessment of marine heatwaves has concluded that they have “the capacity to restructure entire ecosystems and disrupt the provision of ecological goods and services in the coming decades".
