How do increased CO2 levels affect plant growth?



  1. 0 Votes

    Growth-spurring impacts of excess atmospheric CO2 are not uniform by plant type, and certainly plant growth will be limited by other factors. However, evidence is mounting that, for some terrestrial plants, trees in particular, growth is currently being spurred by increased atmospheric CO2, and/or by wetter growing seasons. For instance, grasses and shrubs become more luxuriant or widespread due to increased CO2 and weather changes, particularly in desert regions of Africa and Asia.
