How Ocean Currents Work (and How We Are Breaking Them)

Season 9 Episode 5 | 12m 38s

Ocean currents are our planet’s circulatory system, and they keep everything from ecosystems to the climate healthy. But we’re changing Earth in ways that threaten to disrupt and even break critical ocean currents like the planet-wide Great Ocean Conveyor. We explain how ocean currents work, how climate change is threatening to disrupt them, and what we can do to stop that from happening.
