King of Currents: A Gulf Stream Journey

The Gulf Stream is the mightiest and warmest surface current of the oceans. We travel the current on research vessels, we measure it with buoys, computer animations and CGIs show its course, its role in the global ocean circulation system and for the climate of the planet.

Is the Gulf Stream in danger of becoming weaker, or even stopping? What consequences would a weaker stream have for people who make their living from the current? And what would it mean for us?
