The Earth Is Becoming Greener
In 2016, a paper was published by 32 authors from 24 institutions in eight countries that analyzed satellite data and concluded that there had been a roughly 14 percent increase in green vegetation over 30 years. The study attributed 70 percent of this increase to the extra carbon dioxide in the atmosphere. The lead author on the study, Zaichun Zhu of Beijing University, says this is equivalent to adding a new continent of green vegetation twice the size of the mainland United States.
