Climate change drove Australia's record hot year, unofficial report claims
The usual suspects (Steffen, Flannery) are at it again. Since there is no statistically significant evidence that there has been ANY global warming for 18 years, the claims of change below are simply false. Steffen is a long-time Warmist extremist. A while back he described the debate in the media over the basics of climate change science as ”almost infantile”, equating it to an argument about the existence of gravity.
Australia's hottest year on record would not have happened without climate change, according to a new report.
The country experienced its hottest day, month, season and calendar year in 2013, registering a mean temperature 1.2C above the 1961-90 average.
The Climate Council says recent studies show those heat events would have occurred only once every 12,300 years without greenhouse gas emissions from human activities.
"In fact, we can say the 2013 record year was virtually impossible without climate change; it wouldn't have happened," Will Steffen, the author of Quantifying the Strong Influence of Climate Change on Extreme Heat in Australia, told AAP. "I mean, no one would bet on odds of one in nearly 13,000."
Based on analyses of data and model outputs, the report says climate change triples the odds that heatwaves of the 2012-13 Australian summer will happen as frequently as they do.
It also doubles the chances of them being as intense. "We're looking at pretty hard numbers on the odds of those things happening without the underlying warming trend due to greenhouse gases," Mr Steffen said.
"In my view, it's extremely powerful, conclusive evidence that not only is there a link between climate change and extreme heat, climate change is the main driver of it."
Mr Steffen found record hot days have doubled in Australia the last 50 years, and that during the past decade heat weather records were set three times more often than cold ones.
The report also claims heatwaves across Australia are becoming hotter, lasting longer, occurring more often and starting earlier.
2014 was Australia's third-warmest year on record behind 2013 and 2005, according to the Bureau of Meteorology.
