An international team, led by Australian researchers from the ARC Centre of Excellence for Climate Extremes (CLEX) and the Institute for Marine and Antarctic (IMAS) studies, have published in Nature Communications the first global assessment of the major drivers of marine heatwaves.

CLEX researchers with the Bureau of Meteorology have created a new 20-year-long regularly updated precipitation dataset for Australia using 50 radar sites. This will allow researchers to examine the climatology of extreme events, follow cloud processes, estimate hail size, determine cloud top height and much more.

Dr Mandy Freund and CLEX colleagues have produced a world first 400-year long record of El Niño activity. It’s a record that was previously considered impossible to extract from coral cores.

CLEX researchers and colleagues from Australia, Germany and the US have quantified the effect of climate extremes, such as droughts or heatwaves, on the yield variability of staple crops around
the world. Overall, year-to-year changes in climate factors during the growing season of maize, rice, soy and spring wheat accounted for 20%-49% of yield fluctuations, according to research published in Environmental Research Letters.
The increase in frequency and intensity of ocean heatwaves over the past 30 years has had profound impacts on certain marine ecosystems and significantly impacted the industries that depend on them. According to new research in Nature Climate Change, marine heatwaves are now a clear and present threat to global biodiversity.
