The results surprised Steven Running of the University of Montana and
Ramakrishna Nemani of NASA, scientists involved in analyzing the NASA satellite
data. They found that over a period of almost two decades, the Earth as a whole
became more bountiful by a whopping 6.2%. About 25% of the Earth's vegetated
landmass — almost 110 million square kilometers — enjoyed significant
increases and only 7% showed significant declines. When the satellite data zooms
in, it finds that each square meter of land, on average, now produces almost 500
grams of greenery per year.
Their 2004 study, and other more recent ones, point to the warming of the
planet and the presence of CO2, fertilizing the biota and resulting in the
increased green side effect." Link to Original Source
