Human actions blamed for scorcher year
CLIMATE change was behind the country's hottest year - and we're to blame.
The Climate Council says 2013 would have been cooler if humans were not around.
Council chief professor Tim Flannery said scientists could now tell what influence climate change had on heatwaves.
He said more than 100 hot temperature records were broken in Australia in 2013.
"Carbon emissions must be reduced rapidly and deeply if the worst of extreme heat is to be avoided," he said. "Australians are already feeling the impact of climate change as Australia gets hotter."
The recently released Quantifying the Impact of Climate Change on Extreme Heat in Australia report found the number of record hot days across Australia had doubled since 1960.
"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."
