Climate experts say more extreme rainfall in Australia is likely in the future

Climate experts say recent flooding in Australia has been on an unprecedented scale, but warn the country will face further disasters as climate change brings more regular bouts of extreme rainfall.

A report released on Thursday March 10 by the Climate Council, a non-governmental organization which advises on climate change, found that the ‘rain bomb’ that hit south-east Queensland, including Brisbane, caused around 60% of the region’s average annual consumption. rainfall in three days.

The report says disasters are the result of shorter-term weather factors such as the La Nina weather pattern, but adds that “the likelihood and intensity of extreme and highly destructive events like these increase with change. climatic”.

He said Australia needed to accelerate its carbon reduction proposals to achieve net zero emissions by 2035, rather than 2050.

“Governments, such as the Morrison government, which had failed to substantially reduce emissions before, condemned communities in Australia and around the world to more dangerous extreme weather events,” the report said.

A Climate Council expert, Professor Will Steffen of the Australian National University, said Australia was “dealing with a climate system on steroids”.

“Unless we act now and join the rest of the world in reducing emissions this decade, such disasters will only get worse,” he said in a statement.

For the people of Sydney, it was impossible to escape the incessant rain.

Dr Chia Yeow Tong, a 47-year-old Singaporean who has lived in the city for 10 years, said the downpour was abnormal.

Dr Chia, a lecturer in history education at the University of Sydney and a member of the executive committee of the Australian Malaysian Association in Singapore, said his house had not suffered any damage and that the main impact for him had been transport problems after the flooding of the roads and the delay of the trains. .

“I don’t think I’ve seen anything like that,” he told the Straits Times. “There have been floods before, but it’s the extended period that’s unusual.”

He added: “I wonder what happens over time. Is it La Nina, climate change? Are we going to have these floods once in a while and then a few years of drought?”
