When Chilean researcher Dr Erasmo Macaya from Universidad de Concepción and Centro IDEAL stumbled upon foreign kelp washed up on an Antarctic beach, he knew he had found something significant. Research by an international, multidisciplinary team of scientists reveals just how important that finding was.
Asthmatics and those affected by polluted environments living around major cities along Australia’s east coast could find life much harder over the next 50 years as stronger inversion layers caused by climate change trap more pollution.
Past observations suggest future global warming may eventually be twice as warm as projected by climate models under business-as-usual scenarios and sea levels may rise 6m at 2°C.
The Centre of Excellence for Climate Extremes was officially launched on Tuesday, April 10, at the University of New South Wales (Sydney) by the Minister for Small and Family Business, the Workplace and Deregulation, The Hon. Craig Laundy MP.
Students and ECRs have an opportunity to take part in a voyage to a standing meander of the Antarctic Circumpolar Current (ACC) south of Tasmania. They will undertake a 3-dimensional survey of the velocity and density structure of the meander, deploy a fleet of EM-APEX profiling floats and conduct time series measurements.
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.
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.
There are clear winners and losers for wind power generation across Australia in the century ahead even though climate change will have little impact on wind speeds, according to new research by the ARC Centre of Excellence for Climate Extremes and School of Photovoltaic and Renewable Energy Engineering at UNSW.
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.
Summer in some regions of the world will become one long heatwave even if global average temperatures rise only 2°C above pre-industrial levels and certain regions may become close to unliveable if temperatures increase by 5°C. Even with just a 1.5°C increase in global temperatures there are significant changes to the length, intensity and frequency of heat waves in every part of the world.
