Pops, how exactly can you "plan" for the coming warmth, or the Death Valley heat that's coming our way? The only way to make life sustainable that i can see that is to become a climate refugee, and that's exactly what i plan on doing. Newfie can simple sail off into his water world, but that also has its own extreme limitations on viability. Ibon seems relatively secure in his higher elevations, but that, too, probably can't last forever. About the only planning alternative to geographic relocation is geoengineering.
Perhaps we could plan on and start building cities underground, or under water, or 10,000 feet in the air, or follow Elon Musk to Mars.
I guess my point is that it is practically pointless to individually plan on how to handle the warming temps because, my apologies for this cliche, we're all in this together. If i have a system for staying cool in the oven, there are 7 billion (and growing) other people who will kill me to get their hands on my system so that they, too, can stay alive. I don't think that AGW has any alternatives left for the individual to plan for. We're cooked. The religious can plan on making it into heaven, or some other afterlife paradise. The rest of us can just plan on dying a miserable death.
But, cheer up!

Once it's all over, you won't remember any of it.
