Sea level rise could submerge land currently home to up to 760 million people worldwide if global temperatures rise 4 degrees celsius by the year 2100. So what are cities and city planners going to do to minimize the potential devastation?

Happy holidays everyone! Thanks for a great year!

00:08 I don't know exactly where you are standing, so you might be talking about the land sinking, but unless you are a small child, the sea level will not rise above your head. The worst of the worst predictions (RCP8.5 and 95th% highest scenario) gives sea level rise of 1.2m

I live in a high spot, so I'm safe I guess

Gregory Ferraro says:

Well, my house is definitely safe from sea level rise. I live in Denver. As mean sea level rises, though, we'll have to put a new Mile High marker on the Capitol building.

fowmart says:

a bit late, but carbon dioxide has an atmospheric residence time of 40 years, so if we'd stop emitting TODAY, it would be 2060 before it made a difference in the atmosphere. if we keep going, it doesn't look good for less-developed parts of the world.

I'm not worried about sea levels as sea levels would have to rise hundreds of feet before my home would be threatened.

I won’t believe in global warming until banks stop giving mortgages for beach houses, beach front hotels, etc.

Ignoring the problem is the cheapest solution. YOLO.

No, of course not. Mere millimeters per year (at max) aren't going to drown anyone or anything. https://www.telegraph.co.uk/comment/columnists/christopherbooker/5067351/Rise-of-sea-levels-is-the-greatest-lie-ever-told.html
