The Gulf Stream is the most important ocean-current system in the northern hemisphere, which stretches from Florida to north-western Europe. It incorporates several currents: the Florida current, the Gulf Stream itself, and an eastern extension, the North Atlantic Drift.
How the Gulf Stream behaves is a worry because a slowdown of the Gulf Stream could have consequences for towns on the Mid-Atlantic coast like Norfolk. That's largely because of the current's influence on local sea levels.
