Nonetheless mature forests do play an important role in the global carbon cycle as stable carbon pools, and clearance of forests leads to an increase of atmospheric carbon dioxide levels. (sciencedaily.com)
The continued rise in atmospheric carbon dioxide concentrations has been shown to fuel photosynthesis (and thus growth and reproductive success) in some plants. (britannica.com)
Computer models can be used to study the potential effect of increased atmospheric carbon dioxide on climate. (serc.carleton.edu)
