Documented Shifts in Gulf Stream Pattern

While Mr. Bush and the Flat Earth Contingent ("The Rapture will take us before we have to turn off the ol' AC") tell us science is bad and that global warming is a theory:

One outcome of global warming could be a dramatic cooling of Britain and northern Europe.

Scientists now have evidence that changes are occurring in the Gulf Stream, the warm and powerful ocean current that tempers the western European climate.

Without the influence of the Gulf Stream and its two northern branches, the North Atlantic Drift and the Canary Current, the weather in Britain could be more like that of Siberia, which shares the same latitude.

Cambridge University ocean physics professor Peter Wadhams points to changes in the waters of the Greenland Sea. Historically, large columns of very cold, dense water in the Greenland Sea, known as "chimneys," sink from the surface of the ocean to about 9,000 feet below to the seabed. As that water sinks, it interacts with the warm Gulf Stream current flowing from the south.
