Starting from 1910 when Australia's records start, it took 31 years for the country to rack up 28 days hot enough to fall into that top one per cent. 2013, however, managed to deliver this same number of extremely hot days in a single year.
The report says that seven of Australia's ten warmest recorded years have all happened since 1998. In the last 15 years, "very warm" months are happening five times more often than they were between 1951 and 1980. There are now one third less cool months than before.
Even though cool records can still be set in a warming climate, the report says that since 2001 there are three daytime heat records being broken for every one cold record. Nights are also warming faster than days. For every lowest minimum nighttime temperature record being set, there are now five highest minimum temperature records falling.
The risk of bushfires is increasing too. Across 38 reference stations, the report finds that between 1973 and 2010 there was a statistically significant increase in the number of fire danger days at 16 locations.
