The Gulf Stream is part of what scientists call the "great conveyor belt" that circulates water throughout the world's oceans. There is cause for concern that the increase in global warming might stop the conveyor belt. Would this scenario change Europe's climate?

A) Yes: The Gulf Stream brings cold water from the arctic to Europe. Without this, Europe's climate is expected to be much warmer.
B) Yes: The Gulf Stream brings warm water from the tropics to Europe. Without this, Europe's climate is expected to be much cooler.
C) No: The climate of Europe is unaffected by ocean currents.
D) No: There are other currents that will take over if the Gulf Stream stops functioning.
