Australia has just sweltered through its hottest year on record, according to the Bureau of Meteorology. Average temperatures were 1.20 degrees Celsius above the long-term average of 21.8C, breaking the previous record set in 2005 by 0.17C.
Professor Karoly: “In the model experiments, it is not possible to reach such a temperature record due to natural climate variations alone”
“While many climate extremes cannot be directly attributed to a changing climate, the burden of extremes Australia is experiencing is a product of climate change and requires a coordinated national response.”
The 2013 record high is also remarkable because it occurred not in an El Nino year (where a warm ocean current can push up temperatures), but a normal year. http://www.businessinsider.com.au/more-extremes-of-heat-wind-floods-bushfires-on-the-agenda-after-australias-hottest-year-2014-1
Annual climate statement 2013
Data collected and analysed by the Bureau of Meteorology show that 2013 was Australia’s warmest year on record while rainfall was slightly below average nationally.
- Summer 2012–13 was the warmest on record nationally, spring was also the warmest on record and winter the third warmest
- Overall, 2013 was Australia’s warmest year on record: annual national mean temperature was +1.20 °C above average
- All States and the Northern Territory ranked in the four warmest years on record
- Nationally-averaged rainfall was slightly below average for the year, with 428 mm (1961–1990 average 465 mm)
- Rainfall was mostly below average for the inland east and centre, and above average for the east coast, northern Tasmania and parts of Western Australia

Australia records its warmest spring
The spring of 2013 has been Australia’s warmest on record. Mean temperatures for the season were 1.57C above the 1961-1990 average, surpassing the previous record of 1.43C (set in 2006) by 0.14C. Daytime maximum temperatures were also the highest on record, coming in 2.07C above average and 0.24C above the previous record (also set in 2006), while overnight minimum temperatures were the fourth-warmest on record.
The warmth was most dramatic in September, which saw a mean temperature anomaly of +2.75C, setting a new monthly record by more than a degree. October was also a very warm month, 1.43C above average.
Heatwave expected to hit one-third of Australia over Christmas
This is the first protracted heatwave of the spring-summer period over such a large area.

Heat waves exacerbated by climate change
The Earth has been rebounding out of the little ice age for 300 years –
there is no proof that the rate of warming is out of normal variability,
all the proof is that we are warming within the bounds of normal
variability. 1700- to 1735 warmed at a much faster rate than anything today
with all of our carbon dioxide. Solar cycles drive earths temperature-
carbon dioxide is a minor insignificant factor. Go investigate the facts.
With heat like this in Australia it is making me wonder what the melt
conditions are in Antarctica?
‘the world is cooling for 18 years now’ the retarded idiot deniers say. lol
They will have to lean the hard way that the majority of scientists are
right. My daughters kids will pay the price of our generation folly.
clearly the trillions and trillions of tons of CO2 and multitude of noxious chemicals that humans are discharging into the atmosphere every day – and have been doing so for decades – could not possibly have any effect on the atmosphere whatesoever or impact the climate in any way at all. i mean what kind of logic is that? that’s just so absurd! of course we have to continue to allow the oil industry to maintain it’s totalitarian monopoly over the energy sector and help them maintain their ‘corporate science’ that educates us on the real truth about how climate… Read more »

6 January 2014, Australia’s hottest year was no freak event: HUMANS CAUSED IT by Professor of Atmospheric Science David Karoly & Research Fellow Sophie Lewis at the University of Melbourne. “Using the climate models, the Fraction of Attributable Risk (FAR) shows how much the risk of extreme temperatures increases thanks to human influences. In our earlier study of our record hot Australian summer of 2012-13, we found that it was very likely (with 90% confidence) that human influences increased the odds of extreme summers such as 2012-13 by at least five times. In August 2013, Australia broke the record for… Read more »
