That’s the attitude @Fatso but 100 years?
“As of 2017, average global temperatures had risen 1 C above pre-industrial levels, according to the document. If greenhouse gas emissions continue at their current pace, each decade is expected to bring another 0.2 C of warming – triple the rate of 0.06 degree or so per decade from 1880 to 2012, a period that saw a cumulative 0.85 C rise.”
So divide your 100 years by 3, then add the ever accelerating effects of all the other problems we cause(17 of the last 18 years have broken temp records).
Then you need to think about the wars. They burn energy like nothing else(worlds largest single polluter, the US military) and there’s going to be lots of them.
At least you’re stocking up on food.
