    I think you’re misunderstanding. They are saying that accounting for topography different areas will becomes islands and peninsulas so total landmass might decrease but total coastline could actually increase. Your simplified model only makes sense with a landmass that constantly rises in elevation towards its center point.

    Stupid statement by Trump regardless though.

      Ooh, I didn’t consider that. Good point. Still, without performing the actual calculations it’s quite possible it could reduce. There will be a certain amount of loss from reduced total landmass that would need to be compensated for and overcome by any increases. Reductions will be very, very common after all. Many islands simply disappear, most of Florida, etc.

        Exactly landmass and coastline will trend towards 0 with enough sea rise.

        And looking at a topography map of the US specifically the amount of coastline that could possibly be gained (if any) would not be worth the trade-off of losing pretty much all of SE US. Trump is definitely an idiot.
