Oh, 2022
> low-lying coastal nations like BangladeshAnd lots of other places. About 1 billion people live along coastlines at 20 meters or less above sea level, and 200 million at 5 meters or less. I live in a wealthy country but well within the 5 meters range and am already having to think about whether it wouldn't be more prudent to sell my house today, now that it's still worth something, and emigrate to somewhere with a more future-proof elevation.Worst case if Greenland's ice sheet melts, that adds 7 meters to sea level, and Antarctica's another 60 meters. I won't see that in my lifetime but my children might.
