One of the more dire scenarios being advanced about global warming is the notion that rapid melting of Greenland’s ice sheet could shut down the Gulf Stream, and plunge the entire Northern Hemisphere into a new ice age. Indeed, one British researcher reported a 30 percent reduction in the Gulf Stream in late 2005. But now according to Environment and Climate News, leading publications including Science magazine are reporting much more accurate data from 19 measuring stations attached to buoys in the Atlantic showing no slowing of the Gulf Stream. Since the previous observed slowing was “a mere flicker” in a system prone to natural changes, it looks like you can put away your heavy duty snow shovels and ear muffs.
