National Geographic made precise maps on how Earth would look in the case all the planet\’s ice melted. The bad news: New York, San Francisco, New Orleans, London and other cool cities would be completely gone. The good news: the entire state of Florida would disappear.
But that\’s the only good news. The rest is all bad: on top of the initial massive economic loss, a coastline change like this would provoke unprecedented population migrations across continents, which in turn would generate damage of apocalyptical proportions—pestilence, war, famine, and death would ensue across the globe.
