Is Earth Close to “The Great Dying”?
Are the Great Conveyor Belt and the “Clathrate Gun Hypothesis” about to throw the planet into an existential crisis?
You may remember the 2004 disaster movie The Day After Tomorrow, in which large parts of Europe and the American East Coast suddenly freeze up?
The plot device is that the Great Conveyor Belt — also known as the Atlantic Meridional Overturning Circulation (AMOC) — which brings heat from the south Pacific around the southern tip of Africa and up the east coast of the Americas (we call it the Gulf Stream) into the North Atlantic and Europe shuts down.
The AMOC and the heat it brings to the North Atlantic ocean is the main reason why London (at the same latitude as Calgary) has a relatively temperate climate year-round, instead of being snowbound six months out of the year.
