Fifty years of Miami real estate data demonstrate a real world impact of sea level rise. As of about 1982, elevation became influential on real estate prices. The higher the land, the higher the appreciation (in general.) Houses sitting at less than one meter above sea level have valuation multiples of about half those of houses on higher ground. The gap grew greater starting circa 2000. Ironically, the higher ground typically has been occupied by poorer people. They may see their valuations rise, but if they sell they may not be able to afford houses in the area. Political and scientific debates aside, rising sea levels are already affecting billions of dollars of property and creating climate migrants within the US.
