My primary concern is the sea is rising at over 3 mm per year. If this increases to 10mm per year, as projected, then we are in big trouble on this island.
The engineering works to combat this would be enormous.
I wouldn't be too concerned about an actual severe storm event now and again too much.
I thought it pretty fair and balanced on the whole regarding sea level rise issue. The guy speaking is an aspiring physicist and climate scientist.
