Nevermind the fact that coastal islands have always ebbed with the tides, taking land and homes alike off into the sea for as long as we've lived on coastal islands. Heck, I can remember reading about it in the encyclopedia way back in the protozoic era (i.e., 1985).
Clearly, for islands to have the audacity to recede in the modern era, there must be a more sinister cause.
Enter: Global Warming. Or, as I like to call it, the "fast track to funding."
Far be it from me to cynically suggest that global warming is causing bank account erosion over at my household, which can only be cured by the fast action of the blind Federal bureaucracy.
