Sea Level Rise vs Atmospheric CO2

A map showing what the coast lines of Western Europe will look like with a 20-metre sea level rise.
Manmade Carbon CO2 Pollution Has Already Put Us on Track for 20 Metres of Sea Level Rise

The bad news is that we’re all but certain to end up with a coastline at least this flooded: 20 metres or 69 feet The “good” news is that this might take 1000 to 2000 years (or longer/shorter), and the choices we make now can affect the rate of rise and whether we blow past 69 feet to beyond 200 feet.
