And the chief cause of global greening we’re experiencing? It seems to be that rising carbon dioxide emissions are providing more and more fertilizer for plants, the researchers say. As a result, the boom of global greening since the early 1980s may have slowed the rate of global warming, the researchers say, possibly by as much as 0.2 to 0.25 degrees Celsius.
“It is ironic that the very same carbon emissions responsible for harmful changes to climate are also fertilizing plant growth, which in turn is somewhat moderating global warming,” says study coauthor Dr. Jarle Bjerke of the Norwegian Institute for Nature Research.
It’s a negative feedback…..
