Great Ocean Conveyor Belt: Part II

A very important but little-known network of currents constantly circulates the water in Earth's oceans. What's more, these currents redistribute heat, moving it from the tropics toward the poles, and keeping some regions far more habitable than they would be otherwise. In this audio segment from National Public Radio, scientists discuss the hypothesis that global warming might be causing the Great Ocean Conveyor to slow, and may ultimately cause it to shut down.
