Re: kids, I have no idea. I can honestly only handle this with the level of detached analysis I do because I don't have kids. If i did... I would be seriously considering things that one shouldn't type onto message boards at this point.
FWIW, in an attempt to be constructive. If you do rudimentary math around the size of the problem and the timeline to address it, the only person who has even come close is Bernie Sander's plan. This will require an investment, from the US alone, in the 10 - 100T order of magnitude range. Bernie's plan is 16T. Everyone else is in the single-digit Ts.
So if you believe in science, math, and your childrens future... you kindof have to be like not just voting for but actively canvassing/phone-banking/campaigning for Bernie (assuming you're in the US).
