STUDY: Rising CO2 levels greening Earth – Equivalent to two times the continental USA
CO2 Greening : equivalent to two times the continental United States
Carbon Dioxide Fertilization Greening Earth, Study Finds
An international team of 32 authors from 24 institutions in eight countries led the effort, which involved using satellite data from NASA’s 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. The greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States.
