A new scientific study published in April in the journal Nature Climate Change reveals that between 25% up to possibly 50% of Earth’s vegetated lands have shown significant greening over the last 35 years. Moreover, the study says that the greening is largely due to rising levels of atmospheric carbon dioxide.
The study was carried out by an international scientific team consisting of 32 scientific authors from 24 institutions in eight countries. They used satellite data from NASA’s goods Moderate Resolution Imaging Spectrometer and the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer instruments to help determine the leaf area index, or amount of leaf cover, over the planet’s vegetated regions. They found that the measured greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States. The research determined that increased “fertilization” by CO2 accounted for fully 70% of the planet’s increased greening area, with increased nitrogen deposition another 9%. That’s an impressive statistic...
