Despite their greater age, big, old trees remove more carbon dioxide from the atmosphere, said a study Wednesday that explores how well forests slow global warming.
Despite their greater age, big old trees do more than small young ones to remove carbon dioxide from the atmosphere, said a study that explores how well forests slow global warming.
The findings overturn the conventional view that old trees are relatively unproductive in absorbing heat-trapping greenhouse gases.
In more than 400 tree species studied, the bigger and older specimens grew fastest and trapped the most carbon, the scientists found.
“In human terms, it is as if our growth just keeps accelerating after adolescence instead of slowing down,” Nathan Stephenson of the U.S. Geological Survey said of the findings, published Wednesday in the journal Nature.
