Average winter temperatures in northern Europe are at least 10 degrees Fahrenheit warmer than similar latitudes on the northeastern coast of the United States and the eastern coast of Canada. The same phenomenon happens over the Pacific, where winters on the northeastern coast of Asia are colder than in the Pacific Northwest. Researchers have now found a mechanism that helps explain these chillier winters -- and the culprit is warm water off the eastern coasts of these continents.
