A climate change report has painted an alarming picture of the effect on Australia if global temperatures increase by more than an average three degrees Celsius.
Under that scenario, heat-related deaths would triple, people would be displaced en masse from the coast and national icons like the Great Barrier Reef would almost certainly be lost, according to the analysis by the former head of the CSIRO’s Climate Impacts Group.
The frequency of bushfires would double and there would be major extinctions of animal and plant life, Dr Barrie Pittock says in the report commissioned by WWF Australia.
On an even more serious note, such a rise in temperature would almost certainly trigger an unstoppable climate tipping point – which may occur with a global warming of two to three degrees Celsius, Dr Pittock said.
