Heresy Snowboarding

Thanks for checking back, we really appreciate it.

The Australian Bureau of Meterology (BOM) has an excellent analysis of the latest here [PDF], which Barry Brooks at Brave New Climate has summarised neatly here.

Note the temperature anomaly for this period below. Some parts of Victoria have seen an +18 degree or more temperature anomaly. 18 degrees!

From the BOM (unofficial source within the BOM):

“Given that this was the hottest day on record on top of the driest start to a year on record on top of the longest driest drought on record on top of the hottest drought on record the implications are clear…

It is clear to me that climate change is now becoming such a strong contributor to these hitherto unimaginable events that the language starts to change from one of “climate change increased the chances of an event” to “without climate change this event could not have occured”.

The official BOM statement says:

On the morning of 29 January, an exceptional event also occurred in the northern suburbs of Adelaide around 3 a.m. when strong north-westerly winds mixed hot air aloft to the surface. At RAAF Edinburgh, the temperature rose to 41.7°C at 3.04 a.m. Such an event appears to be without known precedent in southern Australia…

The January-February 2009 event has now been responsible for seven of the eight highest temperatures on record in Tasmania; a total of eight sites reached 40°C, a mark which had only been reached on 16 previous occasions in the state’s recorded history…

On 7 February (Figure 2), the focus of the most extreme heat, which was accompanied by high winds and very low humidity, was in Victoria. An all-time state record was set at Hopetoun, in the state’s north-west, when the temperature reached 48.8°C, exceeding the old record of 47.2°C, set at Mildura in January 19395 by a considerable margin. Seven other sites, in the Wimmera and in the area immediately west of Melbourne, also exceeded the old record, including Avalon Airport (47.9°C), Horsham (47.6°C), Longerenong (47.6°C) and Laverton (47.5°C). The Hopetoun temperature is also believed to be the highest ever recorded in the world so far south. A total of 14 sites exceeded the previous Victorian February record of 46.7°C…

Many all-time site records were also set in Victoria on 7 February, including Melbourne (154 years of record), where the temperature reached 46.4°C, far exceeding it’s previous all-time record of 45.6°C set on Black Friday (13 January) 1939. It was also a full 3.2°C above the previous February record, set in 1983. Three of Melbourne’s five hottest days have now occurred during this event. Geelong (47.4) and Wilsons Promontory (42.0) were among long-term sites which broke all-time records which had been set only the previous week. In total, of the 31 currently open sites in Victoria with 30 years or more of data which reported on 7 February, 21 set all-time records, five set February records, and only five failed to set records at all. 7 Record high temperatures for February were set over 87% of Victoria…

Both Adelaide and Melbourne set records for the most consecutive days above 43°C. Adelaide’s temperatures were at this level on each of the four days 27-30 January, and Melbourne’s for three days from 28-30 January, breaking the previous records of two at both locations… Adelaide ultimately had nine consecutive days above 35°C; after never having experienced more than eight consecutive days above 35°C before March 2008, it has now happened twice within twelve months…

Melbourne had no measurable rain from 4 January to 7 February, the equal second-longest dry spell on record for the city (35 days). This approaches the record of 40 days set in 1954-55. Melbourne (0.8 mm) had its second-driest January on record, and with only 2.2 mm to 8 February has now experienced its driest start to a year on record.

Hmmm, doesn’t sound so global cool-ish to me.
