Climate change causing heatwaves, research shows
HEATWAVES are occurring five times more often due to climate change, new research has revealed.
A new Nature Climate Change journal study found heatwaves which used to occur every three years had increased in frequency to 200-day intervals over the past century.
Researchers attributed three-quarters of the world's heatwaves to climate change, and predicted a 60% increase in extreme rainfall events similar to the three-day storm which lashed NSW last week.
Climate Council CEO Amanda McKenzie said governments had to shift towards sustainable energy.
"As scientists get better and better at calculating the influence of climate change on extreme weather events, the case for accelerating action on climate change is strengthened," she said.
"But the good news is that clean energy technologies, such as solar and wind, are advancing rapidly and are now competitive in price with fossil fuel technologies in many places.''
