SNIP: Even if the Paris agreement to limit the global temperature rise to below 2C is met, summer heatwaves in major Australian cities are likely to reach highs of 50C by 2040, a study published on Wednesday warns.

The lead author of the study, the climate scientist Dr Sophie Lewis, said Sydney and Melbourne could expect unprecedented summer temperatures of 50C under two degrees of global warming.

Governments needed to start thinking about how the public transport system would cope during peak hour in extreme temperatures, how emergency departments would respond to increased demand from elderly people and others vulnerable to heatstroke, and how energy requirements would be met during peak temperatures, she said.

“I don’t think we have any plans in place that would be adequate to withstand days of 50 degrees and it is another urgent warning to our leaders and all levels of government that we need a strong plan to cut commissions and deal with climate change.”
