How Do Ocean Currents Regulate Global Temperature Patterns?

Quick fact

Without ocean currents, the equator would be about 14°C hotter and the poles would be 20°C colder, making much of the planet uninhabitable.

Why this is interesting

Imagine a giant invisible conveyor belt moving water across the entire planet, carrying heat from the scorching equator toward the icy poles. How does this underwater system keep our world from freezing or burning?
