Australia's Hottest Summer Beats Previous Record by 'Large Margin' (brisbanetimes.com.au)

As Australia welcomes the first day of autumn with a sigh of relief, the summer statistics have arrived from the Bureau of Meteorology confirming suspicions that the country just sweated through it's hottest-ever summer. From a report: The national mean temperature for summer smashed the 1961-1990 average by a whopping 2.14C, almost a full degree above the previous hottest summer on record (2012-2013), which was 1.28 degrees above the old average. The mean maximum temperature also beat the 2012-2013 mean maximum by a similar margin (2.61 degrees above average compared to 1.64 degrees above). "It was exceptionally warm across most of the country," the weather bureau's summary states, with NSW, Victoria, Western Australia and the Northern Territory all recording their hottest-ever summer as severe and lengthy heatwaves spread across much of the country in December and January.

Re:Weather isn't climate

[hey!]

Whenever you ear a report of a hot or cold spell, I recommend visiting University of Maine's Climate Reanalyzer site to look at the temperature anomaly maps. This gives you a far better picture of what's going on globally than local reports do.

For example in this winter's bitter cold spell in North America, you would have seen extremely high temperatures in places like Svalbard Norway. This shows that the cold temperatures in the US midwest weren't the *globe* being colder, they were in fact the consequence of the incursion warm air from the temperate latitudes into the Arctic. Since temperatures mix very slowly on a global scale, the cold Arctic air was displaced southward into central North America. When those cold temperatures "disappeared" a few days later, to be replaced with record warm temperatures, they actually just moved to a different place (e.g. the North Atlantic).

Of course this is still weather, but it's weather compared to a long term climate *baseline* -- 1979-2000. If you make a habit of visiting this data site you'll get used to seeing the globe mostly *orange*, meaning hot compared to the baseline. Eight of the past ten years are among the ten hottest years in the instrumental record. Nine of the last ten were among the hottest when they happened. To see an extensively *blue* (cool) map, you'll have to wait for the next major La Nina event, although in all probability that will still be hotter than baseline most of the time.
