The latest science shows that the rate of ice loss from Greenland and Antarctica is increasing. That soon will become the primary contributor to global sea-level rise, overtaking ocean expansion from warming waters and the melting of mountain glaciers and ice caps, said the study, submitted to the California Ocean Protection Council.

That ice loss causes higher sea-level rise in California, it said, due to how the Earth rotates and gravitational pull on the waters. If the ice melt is from West Antarctica, impacts extend further. “For California, there is no worse place for land ice to be lost than from the West Antarctic Ice Sheet,” the study said. “For every foot of global sea-level rise caused by the loss of ice on West Antarctica, sea-level will rise approximately 1.25 feet along the California coast.”

Melting in Antarctica puts the California coast essentially “in the bull’s-eye” of the magnified sea-level rise, said Dan Cayan, director of the Climate Research Division at the Scripps Institution of Oceanography in San Diego….
