Yeah it is horrifying. A big realisation for me this year is how people and other life forms can only really function in quite a narrow range of temperatures.
And even if we completely stop emitting greenhouse gases right now, everything is going to keep getting hotter unless we remove all of the excess. If that farmer's trees do manage to recover they will only get clobbered even harder in future.
I've cared about the environment for a long time but it's insane that I've only just understood this basic fact and that it's no thanks to the government or mainstream media that I have. It feels like a bad trip.
