If a huge forest fire is heading for your city, can you stop it? The correct answer is, "somewhat".
If we do nothing about climate change then the oceans will become acid, the wheat belt will become a dust bowl and the forests will mostly become dead sticks standing. Your firstborn won't be slain. His/her grandchildren will probably be hungry. Not good.
We will probably be saved by solar and other new technologies. Your house will store and then use solar heat in January. Your "car" will use elevator technology, will travel above street level and will use 1/10 the electricity of your current car. Your nighttime and cloudy day electricity will probably come from solar heat stored in huge insulated rock beds of some sort, although I can think of several competitors here. Finally, we're going to find an affordable alternative to losing half of Florida. I recommend, first, pulling heat out of the upper Arctic Ocean with thermosiphons, until the Arctic Ocean refreezes its ice pack to the usual depth, and second, coating tundras and ice sheets with new snow from wind powered snowmaking machines until they have their original albedo back. Faced with megadeath, yes already, we've got that pocket change.
Now for a piece of bad news: a really neat solar photovoltaic coop in Massachusetts sank $30,000 into prepping a solar field. They asked how much it would cost to connect to the local grid. The first answer: $10,000 to find out how much. They paid the $10,000. The final answer, $710,000, maybe more. Suddenly the solar field was no longer financially viable, so the coop ate their $40,000 investment and walked away. The general feeling was that the utility's outrageous connection fee was entirely political retribution in its nature. It's a free market, but free for who?
Bottom line: the practical research and B-corporation business development that will save your own great grandchildren is under direct political attack. You want to defend current solar R&D by companies that care because you are equally defending the lives of your own descendants.
If your state or region has foresight, you'll come up with a pool of money dedicated specifically to solar and climate practical research and product development, and the recipients don't have to be filthy rich to use the money, they just have to have a meritorious new idea. Then your particular state will almost certainly have created vast numbers of regional jobs, following in the footsteps of, to name a successful example, Denmark and their wind power industry.
If no such state has foresight, well, in the long term you're just a dead man walking. The fire is coming.
