Australia is the Canary in the Global Waming Coal Mine

The future is here, and it is Australian. This map shows the expected spread in the range of dengue fever on the continent - almost all the way to Sydney.



According to this LA Times article, Australia is experiencing some of the first pronounced effects of global warming:
They call Australia the Lucky Country, with good reason. Generations of hardy castoffs tamed the world's driest inhabited continent, created a robust economy and cultivated an image of irresistibly resilient people who can't be held down. Australia exports itself as a place of captivating landscapes, brilliant sunshine, glittering beaches and an enviable lifestyle.

Look again. Climate scientists say Australia -- beset by prolonged drought and deadly bush fires in the south, monsoon flooding and mosquito-borne fevers in the north, widespread wildlife decline, economic collapse in agriculture and killer heat waves -- epitomizes the "accelerated climate crisis" that global warming models have forecast.

With few skeptics among them, Australians appear to be coming to an awakening: Adapt to a rapidly shifting climate, and soon. Scientists here warn that the experience of this island continent is an early cautionary tale for the rest of the world.
Among those cautionary experiences: a heat wave that killed 200 people in February, followed by fires that killed another 173, as well as - and this astonished me - "a quarter of Victoria state's koalas, kangaroos, birds and other wildlife." Meanwhile, the drought in Victoria has desiccated the country's breadbasket; rainfall has been less than half of average for more than a decade. The article characterizes the agricultural sector as "collaps[ing]," along with the country's self-sufficiency in food production. And even as the once-fertile south literally dries up and blows away, the tropical wet season in the north is becoming longer and more severe, with flooding and cyclones becoming more frequent. Higher water temperatures are bleaching the coral of the Great Barrier Reef, with one report saying the reef will become "functionally extinct" by 2050. That's barely 40 years from now. Inland wildlife, meanwhile, is being chased up the slopes of Australia's smallish mountains by advancing heat.

Australia, however, likes to burn coal. Its people enjoy the electricity provided by burning coal, and they like the economic growth that comes from such a cheap energy source. So, they are the world's highest per-capita producers of greenhouse gases, which means they are contributing disproportionately to the withering and charring of their own country. That is, you'll note, ironic.

Australia. Apocalypse. I think we all know where this is headed.

Australia Fires

Via Jeff Masters, here's a satellite image of the plumes of smoke from the fire areas of southeastern Australia.



Says Masters:
It is difficult to imagine more hellish fire conditions than those observed in Victoria state's capital, Melbourne, on Saturday (February 7). The temperature soared to 115°F (46.4°C), the hottest ever recorded in the city, besting the previous record of 114°F (45.6°C) set on January 13, 1939. Humidities as low as 4% and sustained north winds that reached 43 mph, gusting to 51 mph, accompanied the furnace-like heat. The dry winds were easily able to fan fires in the parched vegetation. Severe drought conditions reign in Southeast Australia, where some regions--including the city of Melbourne--have experienced their worst drought on record over the past eight years.

More than 170 people have died in the fires so far. The weather events that allowed the conflagrations to flourish - including drought and high temperatures - are consistent with those predicted by most climate models that anticipate significant global warming.
