I honestly don't know how I'd react...definitely would avoid having kids if I knew that was the case. Would be kinda scary...could see myself wilding out as I got closer to the exact date (assuming I knew it).
That said, I agree with dude that said things are going to get
really ugly once climate change starts to set in. I guess I'd stop short of calling it the end of the world, but things will definitely change for the worst.
Droughts, famines, heatwaves, floods, coastal cities destroyed, resource shortages, wars...shyt won't be pretty at all.
