Do Plants Really Slow Global Warming?

June 2006
USA Today Magazine;Jun2006, Vol. 134 Issue 2733, p6
The article focuses on the limited capacity of plants to counteract global warming according to research from Northern Arizona University in Flagstaff. The main reason for the plants' limited capacity is their dependence on nitrogen and other trace elements. Bruce Hungate of the Merriam-Powell Center for Environmental Research found that the nitrogen fixation process cannot keep up with increasing carbon dioxide unless other essentials nutrients are added as fertilizers. About half of the carbon dioxide emitted into the atmosphere is stored temporarily by the ecosystems on land and in oceans.
