How climate change influenced Australia’s extreme weather in 2014

Scientists have linked climate change to several extreme weather events that hit Australia last year, including city melting heatwaves, record hot spring temperatures and the sweltering conditions that greeted the G20 meeting in Brisbane.  They are part of a series of new studies – published in a special edition of the Bulletin of the American Meteorological Society – examining the emerging scientific area of extreme weather “attribution”


The Adelaide heatwave: 13 to 17 January 2014

The city of churches sweltered for five consecutive days with temperatures above 42 degrees. On January 16, when temperatures hit 44.2 degrees, the World Metrological Organisation declared Adelaide the planet’s hottest city that day. To beat the heat the city council set up big fans and water mist sprays in Rundle Mall and warned people to dress light and stay out of the heat. There were reports of numerous hospital admissions for heat related health problems.

FINDING: Human caused climate change has increased the likelihood of an Adelaide heatwave like the January 2014 event by at least 16 per cent and by a best estimate of 186 per cent.
