Australia wildfires that have killed 84 people are more proof that global warming is a real threat.
Towering flames razed entire towns in southeastern Australia and burned fleeing residents in their cars as the death toll rose to 84 on Sunday, making it the country's deadliest fire disaster.
At least 700 homes were destroyed in Saturday's inferno when searing temperatures and wind blasts produced a firestorm that swept across a swath of the country's Victoria state, where all the deaths occurred.
"Hell in all its fury has visited the good people of Victoria," Prime Minister Kevin Rudd told reporters as he toured the fire zone on Sunday. "It's an appalling tragedy for the nation."
This from the Guardian:
Scientists are reluctant to link individual weather events to global warming, because natural variability will always throw up extreme events. However, they say that climate change loads the dice, and can make severe episodes more likely.
Some studies have started to say how much global warming contributed to severe weather. Experts at the UK Met Office and Oxford University used computer models to say man-made climate change made the killer European heatwave in 2003 about twice as likely. In principle, the technique could be repeated with any extreme storm, drought or flood – which could pave the way for lawsuits from those affected.
Bob Brown, a senator who leads the Australian Greens, said the bushfires showed what climate change could mean for Australia.
"Global warming is predicted to make this sort of event happen 25%, 50% more," he told Sky News. "It's a sobering reminder of the need for this nation and the whole world to act and put at a priority our need to tackle climate change."
Models suggest global warming could bring temperature rises as high as 6C for Australia this century, if global emissions continue unabated, with rainfall decreasing in the southern states and increasing further north. As if to demonstrate that, Queensland, in the north, is currently experiencing widespread flooding after rainfall of historic proportions.
More than 60% of Queensland has been declared a disaster zone in the worst floods for more than 30 years. Some 3,000 homes have been affected, and the main highway between Cairns and Townsville has been cut off.
The government is warning us about how bad it will be:
The Environmental Protection Agency (EPA) has issued a strong warning that global warming will have "substantial human health impacts" within the next few decades. The warning came in a report released only days after the same agency declined to regulate global warming-causing greenhouse gases as pollutants under the Clean Air Act.
"Today typifies the climate-change schizophrenia in the Bush administration," said U.S. Rep. Edward J. Markey, chair of the House Select Committee on Energy Independence and Global Warming. "On one hand, government scientists are saying that global warming poses grave threats to our health and our welfare, and, on the other hand, [there] are White House political hacks following the oil industry's bidding to do nothing."
The EPA report warns that rising temperatures will cause air quality to worsen in Eastern cities, as well as more deaths among the elderly, the poor and inner-city dwellers during future heat waves.
"It's going to be hotter; it's going to be hotter sooner in the year than it was in the past," said co-author Kristie Ebi. Young people now living near Washington "[are] going to look back and think back about how nice the summers used to be," she said. "Within 20, 30 years, on average, the [public] should notice that it's warmer."
Global warming is also likely to lead to more frequent and powerful hurricanes, dwindling water supplies in the West, loss of coastal land to rising sea levels and storm surges, and the more rapid spread of food- and water-borne illnesses.
