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.

above ~35 C a breeze makes it worse.

This has happened to the earth before, the earth will change, Northern Atlantic will freeze over, stopping the currents of the ocean, and raise water levels at least several meters, enough to flood most cities on the East Coast.
