"The average temperature of the planet was about 0.5°C warmer than it is today—and climate projections predict it will be again within decades. The global sea level was also 5 meters to 10 meters higher than current levels. Many scientists believe the collapse of the West Antarctic Ice Sheet and consequent melting could have been a primary reason." So there's a good chance the inevitable 0.5°C warming will be followed by a massive raise of the ocean waters. That will have some interesting effects on the society. No wonder Mark Facebook and probably most of the other billionaires are building bunkers.
