Today, as I had a look at the latest BOM forecast showing that Melbourne will be over 30˚ for the next seven days – and the forecast goes no further – it is painfully clear to me that we are seeing a move into another phase of runaway climate change.
As you should be able to see from the latest BOM synoptic forecasts, what is happening is that a stationary monsoon low far south over the continent, and two equally stationary anticyclones to the southwest and southeast of the continent are blocking any cold fronts or cool changes over the southeast and over the west coast. This has produced an endless spell of record hot weather over the historical winter rainfall zone between Northwest Cape and Cape Arid due to continuous flow of hot easterly air without countering flows from the milder ocean.
Synoptic forecast for next four days. Note creation of a super-monsoon over the interior of Australia with cold fronts far to the south of Tasmania. This super-monsoonal circulation is likely to be stable for many weeks, even months, beyond the last forecast day (two days later than this map reaches) |
What the map above shows is that there is not the smallest sign of any cool change over the southeast of the west coast even after the last forecast day of January 27. Instead, what appears to be happening is that the super-monsoon will simply intensify and intensify into the last few days of January, and further into February and March. The persistent block south of Cape Leeuwin will be stationary and forbidding any cool changes for many months. This will mean that Melbourne‘s forecast ten consecutive days (minimally!) over 30˚C will not end until the close of March at the very earliest! Thus, Melbourne will have had sixty-three consecutive days over 30˚C before there is any prospect that a retreating super-monsoon will allow the weather to finally cool. The historic record was eight, occurring four times in:
- 31 January, 1890 to 7 February, 1890
- 28 January, 1898 to 4 February, 1898
- 25 January, 1951 to 1 February, 1951
- 15 February, 1961 to 22 February, 1961
In fact, the most consecutive days over 25˚C in the virgin period up to 1973 was a mere seventeen between 16 January 1951 and 1 February 1951.
This will apply even more to morning temperatures – the possibility of a morning under 20˚C, let alone under the 14˚C that we would average but for our own obscene greenhouse emissions performance, is probably nil until May at the earliest. In the worst-case (and most likely) scenario, we will never see a morning under 14˚C ever again.
There is no doubt that the public is aware runaway global warming is occurring, even if a majority are largely unaware just how responsible Australia is for this looming disaster. This seen via a table of largest greenhouse emitters from Dimitri Lafleur’s 2018 ‘Aspects of Australia’s fugitive and overseas emissions from fossil fuel exports’:

- immediate and radical changes in Australia’s energy, transport and land-use policy are decades overdue
- Australia is every bit as much a rogue state for its abysmal environment performance as the Gulf monarchies are for this and for their support of Islamic terrorism
- global class struggle to ostracise Australia and the Gulf States — with the target of a workers’ revolution to expropriate their oil sheikhs and fossil fuel barons — was overdue in 1996 and is up to forty years overdue now
- runaway anthropogenic climate change is likely to be fatal to a substantial proportion of the human population in the relatively proximate future due to wet-bulb temperatures far above the historic maximum of around 31˚C or 87.6˚F
