This post is misleading. This scenario will only happen after all the ice is melted in Antarctica causing a >200ft sea level rise, which would take at least a couple millenia of extreme global warming to happen. There will be beachfront property slipping into the sea by 2075 with a lot of ecological and economic consequences involved, the NOAA has given us a neat little tool for visualizing what's to come. https://coast.noaa.gov/slr/#/layer/slr
