This passage mainly deals with ____ .
In its full force the Gulf Stream, which begins in the Gulf of
Mexico, carries warm water to a depth of up to 100 meters
at rates of up to 8 kilometres an hour, and penetrates right
up into the Arctic Circle to the north of Scandinavia,
bearing with it a climate that makes life just about
tolerable, even in the thick of the winter. The energy it
carries in the form of heat is equivalent to 100 times the
entire use of energy in human societies across the world
or put another way, more than 27,000 times Britain's
electricity generating capacity. In terms of temperature the
Gulf Stream heats the surface over a wide area by at least
5°C. Were the-Gulf Stream to fail, temperatures over
northern Europe would fall by more than 10 centigrade
degree during the winter months. Northern Europe would
have a climate comparable to that of Siberia: just how it
would support its current population is difficult to
imagine.
