2.3m per degree C. That's about 7ft per degree. And we're looking at a 5C (aka 35ft) rise. And that's without the "leverage" of flat land: you might have to go a mile in land to find the first place that's an inch about the beach. Ever been on a flat beach when the tide came in? You can lose a lot of land to a very small rise in sea...
Thanks. Either way, it seems much simpler to do something similar to what Holland has done than to move millions of people (hundreds of millions if we're talking about the entire world) inland.
I live in Holland so I'm a bit worried about what is going to happen to this place which was already below sea level, despite having the world's best water engineers, a functional cooperative society, and no shortage of capital.
