  •  the rate of increase is increasing (0+ / 0-)

    at an increasing rate. Its what scientists refer to as "surprising acceleration" in their observed rates of change.

    1990-1995 - 1mm year; total 5 mm rise
    1995-2000 - 1 mm year; total 10 mm rise
    2000-2005 - 2 mm year; total 20 mm rise
    2005-2010 - 3 mm year; total 35 mm rise
    2010-2015 - 5 mm year; total 60 mm rise

    2015-2020 - 8 mm year projected; total 100 mm rise
    moving shoreline inland 100 feet so that seawalls
    levees and replenishment fail, barrier islands are breached, storm surges begin to break on the mainland, shore road infrastructure to include roads, railroads, bridges, airport runways, marinas, water treatment , sewer treatment, power plants, LPGN and fuel oil storage are destroyed sources of pollution. In Florida south beach restaurants no longer need to buy seafood it lives on the reef they have been transformed into.

    If you extend the observations forward a little what began with the oceans coefficient of expansion due to temperature rise begins to be augmented by melting polar ice.

    2020-2025-13 mm year projected; total 165 mm rise
    2025 -2030-21 mm year projected; total 270 mm rise
    at 300 mm or about 1 foot of rise the shoreline has moved inland 300 feet in flat areas and places like Brownsville Texas are now part of the ocean. The hope of holding temperature rise to 1 degree, mediating climate change by reducing atmospheric carbon is dashed when the release of methane hydrates from siberian lakes and every shoreline around the world causes a "surprising acceleration" in the rate at which atmospheric and ocean temperatures rise.

    2030-2035 -34 mm year projected; total 440 mm rise
    In 2037 the shoreline has moved inland about a furlong
    and most harbors on the east coast are now part of Atlantis
    2035-2040 -55 mm year projected; total 715 mm rise
    by 2033 with a meter rise most east coast nuke plants are becoming very hard to service.

    Even as rising population makes more people dependent on the oceans for food, the increased temperature acidification and salinity of the oceans and atmosphere cause oxygen producing bacteria in the north Atlantic to die off resulting in dwindling fish stocks and serious problems for oxygen breathers generally.

    Fortunately the most likely result is that the cause of the problem will be removed  without us around to cause problems and in a few millenia things will get back to normal
