wonder what their opinion on burning the American flag is

I felt the same way. had extreme stress levels thinking about the future and depression from doomscrolling on r/collapse. Sometimes I still venture over there to see what's going on but I don't let it bother me. At this point, it helps me to be ignorant of the far future. I think a year out maybe at most and occupy myself with what's happening now. we might all die in a nuclear war or the collapse of society in 20 years but what am I going to do to stop it? I prefer to focus on things I can change to make my life better as it happens. I can only hope I am wrong and things will be relatively ok, but that's just hope.

we might all just die, I hope not, but we might, and that's something I am pretty much comfortable with at this point.

No, the requirment is that its flammable. Hydrogen is explosive by itself, jet fuel is just flammable.

I thought we decided that using hydrogen gas as a fuel was a bad idea on account of how extra explosive it is

And next year, and next year

but the effect of higher seas wont be the same along every section of coast, mostly just the low-lying areas will be effected
