[QUOTE="eclipsenow, post: 77654189, member: 274355"] Yes! Have I shared this with you before? Sorry if I have - I'm all over the net these days and forget where I've shared what. I’ve lived through some nasty heatwaves in Sydney that are 47 degrees C. They probably killed an excessive number of elderly or unwell people without access to air that did not have air-conditioning. elderly and frail people without air conditioning than usual. But there are super-heatwaves coming that are vastly more deadly - and at LOWER temperatures. Heatwaves that will kill [I]everyone[/I] stuck outside. The difference? At only about 35 degrees C and 100% humidity, perspiration stops cooling the human body. We start to cook.
