Research brief: Future climate risk from compound events

May 18, 2018 3:38 am Published by Comments Off on Research brief: Future climate risk from compound events

CLEX researchers writing in Nature Climate Change suggest a paradigm shift in how climate scientists approach climate change impact assessments. They suggest examining the system or potential catastrophe first instead of making the starting point a climate scenario.

Research brief: Marine heatwaves increase around Tasmania

April 30, 2018 1:59 am Published by Comments Off on Research brief: Marine heatwaves increase around Tasmania

Centre of Excellence researchers have identified 12 marine heatwave types off the east coast of Tasmania, a location recognised as a global warming hotspot. Here the average sea surface temperatures here have been rising at four times the global average and trends in marine heatwaves are showing significant increases in number.

Research brief: New research rewrites Southern Ocean mixing calculations

World-first modelling research– which used several million CPU hours in Australia’s fastest supercomputer, Raijin, and ran calculations non-stop for over a year – has revealed the Southern Ocean mixes water between the depths and surface far more easily than previously thought.

Research brief: Why record-breaking droughts had very different impacts on Amazon forests

April 17, 2018 3:49 am Published by Comments Off on Research brief: Why record-breaking droughts had very different impacts on Amazon forests

In 2005 the Amazon experienced a once in a century drought. Five years later, in 2010, it was struck by an even worse drought, with even lower rainfall occurring in the dry season. However, the response of the Amazon forest to these two once-in-a-century events showed marked differences.

Hotter, longer, more frequent – marine heatwaves on the rise

An international study in Nature Communications co-authored by researchers from the ARC Centre of Excellence for Climate Extremes (CLEX) and the Institute of Marine and Antarctic Studies (IMAS) reveals globally marine heatwaves have increased over the past century in number, length and intensity as a direct result of warming oceans.

Regional adaptions can cool heat extremes by up to 2-3°C

April 1, 2018 12:07 am Published by Comments Off on Regional adaptions can cool heat extremes by up to 2-3°C

New research published in Nature Geoscience has found that climate engineering that modifies the properties of the land surface in highly populated areas and agricultural areas over North America, Europe and Asia could reduce extreme temperatures there by up to 2-3°C.

Academies call on CHOGM members to do more to fight climate change

March 19, 2018 1:23 am Published by Comments Off on Academies call on CHOGM members to do more to fight climate change

The Australian Academy of Science with 21 other Commonwealth National Academies of Science and societies as part of a consensus statement calling on the members at the next Commonwealth Heads of Government Meeting (CHOGM) to use the best available science to guide action on climate change. The call comes at a time when research has shown that the commitments of the Paris Accord agreed to by international governments will still put the world on track for temperatures 3°C above preindustrial temperatures.
