The year 2500? Who knows what technologies we might have available by then (e.g. fusion power enabling cheap energy to the point where we can do carbon capture and reverse warming). What we are already seeing is that we are trending away from a baseline scenario by electrifying transport, energy generation and energy storage. And it’s probably harder to predict politics than the climate but right now I only see that trend continuing. There are some unfortunate anti-nuclear steps being taken but eventually enough solar and wind will get online to replace them. Emissions in the USA have trended down thanks to fracking and coal being wiped out. Sea levels will rise but new land in the arctic will open up for human habitation and agriculture. Wars and migration may certainly happen but we’ve had plenty of that in the last 200 years without the end of civilization.
