Mark, You say 2030 (15 years from now) that there will be billions in flood damage that is directly connected to the rise is sea levels.
Yet to this day there is no true accurate # as to how much it is rising, if it is increasing/decreasing or the rate that can be used to project the rise over time.
As reported just yesterday..
Bias in satellite measurements hid recent sea level rise acceleration | Ars Technica
"If we add up all our estimates of deposits to and withdrawals from the sea level bank account (things like melting glaciers, the expansion of warming seawater, and changes in the amount of water on land) we get 2.8 ± 0.5 millimeters per year— which suddenly looks a little better. (The tide gauge record comes in at about 2.7 millimeters per year, by the way.)"
So in 15 years that puts it in at 40.5 millimeters or 1.6 inches. I think it is safe to assume that if 1.6 inch rise is rather small when you consider normal sea wave high and tides etc..
But maybe Tesla will start making amphibious electric cars.
