How are plate tectonics contributing to the rise of sea level?

Best Answers

Ocean thermal expansion, or the increase in volume of the oceans as sea water temperatures rise, is responsible for about half of the global rise in sea levels. Melting land-based ice, from glaciers and ice caps, contribute the other half. read more

The observed rate of sea level rise is trivial, constant and not accelerating. It has nothing to do with increasing atmospheric CO2. Any contribution to this from plate tectonics is included in the observed sea level rise that is quantified by NOAA Sea Level Trends data. read more

Sea-level rise rates recorded at NOAA tide gauges for Southern and Central California range from just under 1 mm/year to just over 2 mm/year, while the state's coastline north of the Cascadia Subduction Zone boundary near Cape Mendocino where the ocean plate moves under the continental plate, the coastline on average is rising more rapidly than the rate of sea-level rise. read more

The current effect has been estimated to be -0.3 mm/yr of equivalent sea level rise due to increasing ocean basin size. This effect is corrected in the satellite altimeter global mean sea level time series and contributes 0.3 mm/yr to the estimated global mean sea level. read more
