Warming gas levels hit 'troubling milestone'

13. It's going to be nasty.

We're going to ultimately resort to geoengineering, and I doubt very seriously that we're going to be able to get it just right. The ice caps will melt, that's just a foregone conclusion. We'll be having to deal with the issue from three prongs.

1) Massive 300k+ persons / year migrations out of sea zones that will be affected (you will have to start "early" to move all the people affected, many many people will push back and every year they don't move, there will be thousands more you have to move in the same time frame, eventually they'll get the picture, after enough floods).

2) Highly risky geoengineering which could actually turn the planet into a snowball earth or bring on an ice age if it is not done properly. A perpetually tinted yellow sky. The will of nation states to participate together since the sky / atmosphere is shared by all.

3) All the while you'll have to be doing these things with highly dwindling fossil resources which will impact the growth of society further, and which will shut down globalization in short order.
