A new look at twenty years worth of research shows that polar ice is in fact melting, and raising sea levels, faster than anticipated. Greg Laden writes “Greenland is losing ice about 500% faster now than it was in the early 1990s, while Antarctica is losing ice at about the same rate.” Altogether, ice melt since 1992 “has contributed to about 0.44 inches of sea level rise.” On Stoat, William M. Connolley says “Still – that adds up to 0.6 mm/yr. So it will have to grow if its to become interesting by 2100.” With ice-bound methane poised to mingle with carbon dioxide and accelerate global warming, interesting is a definite possibility. Scientists estimate that sea levels would rise by 200 feet if Antarctica thawed entirely. Not for several millennia, but an industrialist can dream.
