A new study led by The Australian National University (ANU) has warned that Melbourne and Sydney should prepare for 50 degree Celsius days under the Paris Agreement global warming limit of 2 degrees.


Lead researcher Dr Sophie Lewis said the study assessed the potential magnitude of future extreme temperatures in Australia under Paris targets of an increase in global temperatures of 1.5 and 2 degrees Celsius above pre-industrial levels.


“Major Australian cities, such as Sydney and Melbourne, may experience unprecedented temperatures of 50 degrees Celsius under 2 degrees of global warming,” said Dr Lewis from the Fenner School of Environment and Society and the Centre of Excellence for Climate System Science at ANU.


“The increase in Australian summer temperatures indicates that other major cities should also be prepared for unprecedented future extreme heat.


“Our climate modelling has projected daily temperatures of up to 3.8 degrees Celsius above existing records in Victoria and New South Wales, despite the ambitious Paris efforts to curb warming.”


Dr Lewis said immediate climate action internationally could prevent record extreme seasons year after year.
