ScienceDaily (Nov. 17, 2008) — University of Iowa researchers and their colleagues have found a way to improve existing estimates of the amount of carbon absorbed by plants from the air, thereby improving the accuracy of global warming and land cover change estimates, according to an article in the journal Science.
By knowing the effects of plants on the atmosphere, scientists will be better able to determine the amount of human-generated carbon dioxide (CO2) injected into the atmosphere, according to Greg Carmichael, professor of chemical and biochemical engineering in the UI College of Engineering and co-director of the Center for Global and Regional Environmental Research (CGRER).
“This work demonstrates a technique to get a direct estimate of the photosynthetic uptake by plants over large regions,” he said. “This is critical because in the carbon budget analysis we need to be able to quantify the various sources of carbon dioxide, especially the carbon dioxide from anthropogenic activities and the uptake of carbon dioxide by plants.
