I’m getting a bit annoyed with people pushing over-inflated estimates of SRL in the near future. Richard Alley apparently said There is no consensus on how much Greenland’s ice will melt in the near future, Dr. Alley said, and no computer model that can accurately predict the future of the ice sheet. Yet given the acceleration of tidewater-glacier melting, a sea-level rise of a foot or two in the coming decades is entirely possible, he said (though in his defence its not in literal quotes).
But the current rate is 3 mm/yr. If that doubles to 6 mm/yr, then over two decades that would be 120 mm. Which is well short of even 1 foot. So… anyone want to bet on at least 1 foot in 20 years (or could we say 6 inches in 10 years?).
