Via Brian Beutler ... via Thinkprogress ... via The Independant comes a story form Australia with real world global warming consequences.
Australia has warned that it will have to switch off the water supply to the continent's food bowl unless heavy rains break an epic drought - heralding what could be the first climate change-driven disaster to strike a developed nation.There is a lot to digest in this passage, but I think it is very important to see how quickly a government did an about face when global warming was staring them down. Now it is not to say that this drought will lead to the exodus of Aussies in the near future, but eventually, maybe 10 years, maybe 50, the Australian breadbasket, will longer be. The Australians will be forced to permanitley import large quantities of food. As African nations have shown, this is not a very good working stategy for a nation.
...
The Prime Minister, John Howard, a hardened climate-change sceptic, delivered dire tidings to the nation's farmers yesterday. Unless there is significant rainfall in the next six to eight weeks, irrigation will be banned in the principal agricultural area. Crops such as rice, cotton and wine grapes will fail, citrus, olive and almond trees will die, along with livestock.
...
Mr Howard acknowledged that the measures are drastic. He said the prolonged dry spell was "unprecedentedly dangerous" for farmers, and for the economy as a whole. Releasing a new report on the state of the Murray and Darling, Mr Howard said: "It is a grim situation, and there is no point in pretending to Australia otherwise. We must all hope and pray there is rain."
But prayer may not suffice, and many people are asking why crippling water shortages in the world's driest inhabited continent are only now being addressed with any sense of urgency.
The causes of the current drought, which began in 2002 but has been felt most acutely over the past six months, are complex. But few scientists dispute the part played by climate change, which is making Australia hotter and drier.
Environmentalists point to the increasing frequency and severity of drought-causing El NiƱo weather patterns, blamed on global warming. They also note Australia's role in poisoning the Earth's atmosphere. Australians are among the world's biggest per-capita energy consumers, and among the top producers of carbon dioxide emissions. Despite that, the country is one of only two industrialised nations - the United States being the other - that have refused to ratify the 1997 Kyoto protocol. The governments argue that to do so would harm their economies.
Until a few months ago, Mr Howard and his ministers pooh-poohed the climate-change doomsayers. The Prime Minister refused to meet Al Gore when he visited Australia to promote his documentary, An Inconvenient Truth. He was lukewarm about the landmark report by the British economist Sir Nicholas Stern, which warned that large swaths of Australia's farming land would become unproductive if global temperatures rose by an average of four degrees.
Faced with criticism from even conservative sections of the media, Mr Howard realised that he had misread the public mood - grave faux pas in an election year. Last month's report by the UN Intergovernmental Panel on Climate Change predicted more frequent and intense bushfires, tropical cyclones, and catastrophic damage to the Great Barrier Reef. The report also said there would be up to 20 per cent more droughts by 2030. And it said the annual flow in the Murray-Darling basin was likely to fall by 10-25 per cent by 2050. The basin, the size of France and Spain combined, provides 85 per cent of the water used nationally for irrigation.
