Southern Australia just endured its hottest summer ever recorded, and recent research found that the likelihood of more extreme summer weather is on the rise.
Following summer months where Sydney’s mean temperature remained 37 degrees Fahrenheit above average, Dr. Perkins-Kirkpatrick at the University of New South Wales in Sydney began to study the relationship between human-induced climate change and summer heat waves.
Along with other researchers at the World Weather Attribution, Perkins-Kirkpatrick concluded that climate change has made it 50 times more likely that New South Wales will experience another similarly scorching summer. Simply put, before 1910 extreme weather like that experienced this summer was likely to occur once every 500 years, now it is likely to occur every 50 years on average. If climate change remains unabated, researchers say that likelihood could increase even more.
The report said, “In the future, a summer as hot as this past summer in New South Wales is likely to happen roughly once every five years.”
Energy companies in New South Wales had trouble supplying enough electricity to meet the demand for air conditioning units during the heatwave’s most intense days from February 9th through the 11th. Meanwhile, according to report by The Guardian, Australian Prime Minister Malcolm Turnbull criticized renewable energy efforts, calling renewable energy goals in the country “completely unrealistic.”
Dr. Andrew King of Melbourne University was another one of the report’s authors. He said, “Yes, people would have experienced 40C [104 degrees Fahrenheit] days several decades ago around different parts of Australia and in Sydney but we know that these incidences of very hot days are getting more frequent and we are setting more records for heat.”
King added, “The purpose of the analysis in this report is to raise awareness that climate change is already impacting on weather in Australia. Hopefully it motivates action on climate change, because we know what the solution to climate change is.”
