I'm a firm believer that sooner or later we will be extinct by extreme heat and suffocation.
Two weeks ago here in Umbria, Italy the heat was extreme. It was 40°C without a breeze of air, it literally felt like braathing hot air. One morning while I was walking I couldn't believe the amount of dry leaves on the street, by pictures people would have guessed that it was autumn.
I have a really good tolerance to high temperatures but this time I got home very dizzy.
Hope is not too late to revert the current situation, but realistically year after year temperatures have been raising steadly.
