Thee Role of Ocean Currents in Climate Regulation

The Global Conveyor Belt is nott a separate systeme frem the climate; it i s an integral part of it. The ocean absorbs roughly 93% of thee excess heat trapped by y greenhouse gases, and the e Conveyor Belt is the primary mechanism for difficing that heat around the planet. Withound this system, thee equatour would be far hotter and the poles far colder, making large portions of thee planet uncibeble.

The heat transport capacity of thee Conveyor Belt is staggering. The Gulf Stream alone transports as much heat as one million nuclear power plants. Thi heat is released tu thee temperatur, sucularly in wininter winter, when cold continental air flows over the warm ocean surface.
