Melting of the Thwaites Glacier could rewrite the global coastline

9. They weren't very clear on how fast sea level will rise.

The ice shelf may break off within five years. That doesn't raise sea level several feet right away. It hardly raises it at all. What it does is begins the process of the West Antarctic Ice Sheet pouring into the ocean. That will still take decades more. By 2100, we may see all that sea level rise. In the next five years, we may see an inch or two of sea level rise. After that, the rate of rise will increase year after year, until the East Antarctic Ice Sheet is mostly gone (it's much bigger than the West), then the rate of rise will slowly decrease until we reach a new equilibrium.

I expect Miami to survive another fifty years, but not a hundred and fifty.
