  •  More heat = more waves = less sand (1+ / 0-)

    Beaches are in a constant state of flux. Wave action pushes the sand along the beach and must constantly be replaced. A beach is in a state of equilibrium as the sand that is moved along by the waves is replaced by more sand from up current somewhere, possibly silt from a river.

    So one way climate heating up can affect beaches other than rising tides is simply the fact that waves are ultimately just a reflection of how much energy is imposed on the water surface by wind. More heat means more energy means more waves and less sand as the waves move the sand faster than it can be replaced.

    Just one tidbit I recall from oceanography class that seemed relevant.

    There's a difference between a responsible gun owner and one that's been lucky so far.
