Sadly, our system of infrastructure funding is predicated on increasing populations and growing tax bases. A population decline would result in bankrupt cities and even worse infrastructure problems. With a future of climate-induced migrations, we will likely face these problems anyway as people leave areas and never come back (or simply die) after "edge case" disasters strike.
