The most widely feared consequence of global warming appears to be sea level rise (SLR). Environmental advocacy groups are polluting the airwaves and internet with lurid images of flooding of Bangladesh and Pacific islands, and raising the specter of hundreds of millions of environmental refugees. Even sober scientists, while not endorsing such obvious scare stories, predict an acceleration of the ongoing global rise, which a system of tidal gauges places at about 18 cm (7 inches) for the past century, Other scientists stoutly maintain that there has been no acceleration -- even during the strong global warming of 1920-1940. Recall that Obama even predicted a deceleration of SLR when he accepted his party's nomination in 2008: "This was the moment when the rise of the oceans began to slow, and our planet began to heal." So far, the existing data can be used to support all three sides. Some tidal-gauge data tend to show deceleration starting in...(Read Full Article)
