lol not a troll, I really am excited. We're talking about a massive increase in resources, more usable land, more food production (from increased heat and CO2), less ice, etc. it's a positive for humanity, after it all shakes out (yes, there will be adjustments in the intrim).
I'm not really concerned about water. We have the ability to innovate around rising sea levels or changing rain fall. There are plenty of more concerning issues -- microplastics, chemicals, etc.
