30. We should look at coastlines from 125,000 years ago,

the last time we had temperatures and GHG like this, to get an idea what to expect.

Maybe 2 billion people wil get flooded out. Ocean currents and cyclones will change. Food sources will suffer.

Bangladesh in particular will be caught between river floods from glacier melt and monsoons, and rising seas.

Sea levels rose 10 metres above present levels during Earth’s last warm period 125,000 years ago, according to new research that offers a glimpse of what may happen under our current climate change trajectory.

Our paper, published today in Nature Communications, shows that melting ice from Antarctica was the main driver of sea level rise in the last interglacial period, which lasted about 10,000 years.

I haven't found a global map, but here's Florida:

We'll lose the Everglades, the Keys, and the reefs. Think what that will do to Caribbean and Gulf fisheries. That's just one spot.
