EARTH A New Wild

Clip: Episode 3 | 44s

Satellite footage from NASA has revealed how the planet breathes in annual pulses in time with the seasons. And surprisingly the breathing isn’t driven by the tropical forests as would be expected; it’s the great northern forests that are the real lungs. Video courtesy of NASA, graphic ©NASA/JPL-Caltech.
