What's worse is that we can't do shit about what's coming. We are, at best, 20 years behind the environmental curve. What we did 20 years ago is haunting us right now. What we will be dealing with in 20 years, we are doing right now.

The glaciers will melt. The resulting sea level rise will cause more warming(snow/ice reflects solar radiation, the dark ocean absorbs it), causing more glacial erosion, causing more sea level rise.

It won't be Water World, and it won't be The Day After Tomorrow, but the result will be somewhere in the middle of that and what we have now.

What the world will look like will be anyone's guess. It isn't just sea level rise. Desalination, warmer oceans, more powerful storms, the breakdown of the North Atlantic current, followed by breakdowns in other currents, will all effect where humans will be able to live, what crops will survive, and what we will be able to live through.

You think the sudden invention of space tourism is odd? Companies want to put a base on the moon. A self-sustaining base. Where do you think the ultra rich will go hide, when they've finished extracting everything from earth?
