Sea-level is rising due to land-borne snow and ice melt.As the ice melts,some areas experience tectonic rebound,rising,as the weight of the ice is lost.Some parts of North America are still rising from the time of the interglacial.Some geographic areas are experiencing subsidence,as ground water is pumped.
There would also be subduction areas along active tectonic plate boundaries,although this happens at extremely slow rates,with the exception of major earthquakes,as in Japan,where the entire coastline dropped 6-feet,ahead of the tsunami which took out the Fukushima Dai Ichi reactors.
Basically,as the amplification of feedbacks accelerate,we'll be looking at perhaps 66-feet of sea-level rise by 2100.The glaciologists are witnessing what would otherwise be referred to as runaway melting.And a blue ocean event is still forecast for Summer,2030,for the Arctic Ocean.
