Uncertainty over weakening circulation

Letter to Physics Today – March 2007

This is a must read letter to the editor. It really calls into question one of the major beliefs of those who state that global warming will cause cataclysmic damage to our way of life. Basically, many people believe that if the major ocean currents change dramatically, that we will have major changes to our local weather in parts of the world. While this belief has some legitimacy, there does not seem to be a preponderance of evidence that such a change is imminent.
