I live pretty near to the beach, worse still I live in the lowest point of a dip between 3 hills ..... my GPS unit tells me I'm about 8-10 meteres above sea level.
By those maps my yard becomes a small isolated pond around the 12m rise level, with most of my neighbours sitting nicely on the shore looking at my submerged palace.
When the warming progresses it will be time to sell up and by a nice high spot with good dark skies instead.
