I'm very worried too. I have kids. In the next ten or fifteen years I'll probably have grandkids. I'm building up food storage, anticipating periods of high food insecurity. I've done a lot of thinking about what I really need to live a good life, and more specifically what I don't, anticipating that there may well come a time in my lifetime where a lot of the things I now think of as necessities are simply not available. But: there's a saying that engineers tend to over-estimate what can be accomplished in the short term, and under-estimate what can be accomplished in the long term. So I have hope. Renewable energy is getting cheaper than fossil fuels. Electric cars are on the market already, and they're getting better. Economic forces, once tipping points are reached, can cause change to happen very, very quickly. I can imagine a future where nearly all cars on the road are electric within ten to twenty years, and where nearly all electrical generation is renewable/nuclear, and where this happens not primarily due to government action but simply market forces and consumer sentiment. And in the meantime, there are some ugly but eminently doable geoengineering solutions that will keep most of us alive. I can imagine it. So I have hope.
