These images show evidence of just one part of the global carbon cycle, the process that moves carbon from the atmosphere to the biosphere.
Colors in the images indicate plant growth on land and in the ocean over a period of three years. As plants grow, they take in carbon dioxide from the atmosphere. Through photosynthesis, the carbon becomes part of the living plant. Thus, plant growth shows the transfer of carbon from the atmosphere to the biosphere. Seasonal changes in the animation can be viewed as the "pulse" of the global carbon cycle.
