The study published in Nature said this is because the diffusion of sunlight means the land receives light from different directions rather than just directly from the sun. As a result, plants are able to convert more of the sunlight energy into growth, trapping carbon dioxide as they do so, because more leaves are in the sun. The increase in the amount of carbon dioxide, which is a greenhouse gas, may have helped to slow global...(Read Full Post)
