A recent study has shown that the ecosystem's ability to absorb ever-rising levels of carbon dioxide is not only finite, but we may be reaching the limit soon.
The precise ecosystem study of the reaction of a Texas grassland to a range of carbon dioxide levels has shown that soil nitrogen availability may limit the capacity of ecosystems to absorb expected increases in atmospheric CO2. The researchers said their study emphasizes the urgency with which the U.S. and other nations should adopt stringent limitations on CO2 emissions, as outlined in the international Kyoto accord on climate change.
