Carbon dioxide fertilization is greening the Earth

Half of the Earth’s vegetated land has shown a very significant change greening in the past 35 years, due to the rising of the carbon dioxide in the atmosphere. In order to see this change a team of 32 authors partnered up to make their research. It 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. The green leaves use the energy from the sun through the photosynthesis so they can combine the carbon dioxide from the air with water to produce sugar which is the main fuel of the earth.
