The earth experiences what scientists refer to as thermohaline circulation but most people know as the global oceanic conveyer belt. The water deep below the surface doesn't sit still. Differences in temperature create movement, just like in the atmosphere, and water with varying salt content moves to balance denser and lighter particles. The most commonly known example of thermohaline circulation is the Gulf Stream, which spreads warm water from the Gulf of Mexico upwards towards Iceland and Northern Europe. When this slowed in the 19th century Britain and other places in the Northern Hemisphere experienced the "Little Ice Age." It rarely snows in Britain anymore, but it's almost always depicted as snowing or cold in Dickensian London. This is well-known, as opposed to the Clunked Exotics post we brought you today. We thought of it as a good thing, but engineerd channels Dickens to see both sides of it.
