The consequences, of extreme heat, are usually mainstream media material. For example 370 people died from extreme heat in Victoria during the same week that 173 people died from the 2009 Black Saturday fires in the state. The same report predicts that extreme heat in Melbourne could, without mitigation by 2050, kill over one thousand people in an event.
Numbers like these seem to be losing salience in with the Australian public, or at least our media. The lack of reporting certainly enhances research that demonstrates fear won't do it and views that "Our leaders and the community at large are still in denial (or studiously unaware) of the realities of global change"
So what might do it? Beyond Denial: Managing the Uncertainties of Global Change from Australia 21 looks at this. In it:
Paul Gilding, the author of “The Great Disruption,” ... argues that rather than a steady decline, the human world will, in the next one or two decades, experience shocks of such magnitude arising from our disordered economic system, climate change and peak oil, that they will call forth an emergency crisis response that will enable us to harness human ingenuity to craft a genuinely sustainable future for those humans who survive the shocks.There's plenty more here but, of course, no simple solutions for complex entangled problems such as global warming.
