It was 45°C when I was out on the farm last Friday, fortunately a one off, and better than the 48.9°C further inland. I did read that the temperatures had doubled the state's death rate for the week, so you're right about the effects. Evaporative coolers can drop the temperature by more than 10°C for little energy expenditure, which is right handy at those temperatures. But we're on tank water out there, and even 100 litres per day extra consumption is problematic. The neighbours were out of drinking water more than half a year ago, all our dams bar one are dry now, and it's 4m down to the water in it. (Must admit though, there's a subsidy on trucked-in water, and a truckload would last all summer.) The plan is for solar powered aircon and plenty of insulation when the new build gets that far. When PV power is cheap and water is scarce, conventional economics go out the window. Let's hope the frigid vagrant polar winds up your end of the planet are temporary. They're even more lethal, I figure. It's unfortunate that they're pushed south by polar warming, as that's happening twice as fast as the global average, so there'll probably be more of it in the coming years.
