How Global Warming May Be Fueling Australia's Fires - TIME - Monday, Feb. 09, 2009 - By Bryan Walsh -The raging infernos that have left more than 160 people dead in southern Australia burned with such speed that they resembled less a wildfire than a massive aerial bombing. Many victims caught in the blazes had no time to escape; their houses disintegrated around them and they burned to death. As firefighters battle the flames and police begin to investigate possible cases of arson around some of the fires, there will surely be debates over the wisdom of Australia's standard policy of advising residents either to flee a fire early or stay in their homes and wait it out. John Brumby, the premier of the fire-hit Australian state of Victoria, told a local radio station on Monday that "people will want to review that...There is no question that there were people who did everything right, put in place their fire plan and it [didn't] matter, their house was just incinerated."Read the rest of the article here.
(...) Destructive wildfires are already common in Australia, and it's not hard to see why climate change would increase their frequency. The driest inhabited continent on the planet, Australia has warmed 0.9 degrees C since 1950, and climate models predict the country could warm further by 2070, up to 5 degrees C over 1990 temperatures, if global greenhouse gas emissions go unchecked. Beyond a simple rise in average temperatures, climate change will also lead to an increase in Australia's extreme heat waves and droughts. Southwestern Australia is already in the grip of a prolonged drought that has decimated agriculture and led to widespread water rationing; the region is expected to see longer and more extreme dry periods in the future due to steady warming.
