Nature Still Sucking Up Considerable Carbon Dioxide http://apocadocs.com/s.pl?1343857213
While humans are emitting large amounts of greenhouse gases, particularly carbon dioxide, into the atmosphere, the planet sucks some of it back up.
A new study indicates that natural, carbon-removing processes, have not yet reached capacity, in spite of humans' increasing emissions over recent decades.
The oceans can absorb carbon dioxide out of the atmosphere, as can trees and other vegetation.
"Globally, these carbon dioxide 'sinks' have roughly kept pace with emissions from human activities, continuing to draw about half of the emitted [carbon dioxide] back out of the atmosphere," said study researcher and climate scientist Pieter Tans, with the U.S. National Oceanographic and Atmospheric Administration's Earth System Research Laboratory, in a statement. "However, we do not expect this to continue indefinitely."
