But they also found that air quality would actually suffer from an increase in volatile compounds." "So they looked at mixing the forest, emphasizing trees that are good performers when it comes to carbon sequestration and don't emit a lot of junk. They came up with a list of 31 species, including American basswood, dogwood, Eastern white pine, Eastern red cedar, gray birch, red maple and river birch. That combination, they found, would increase carbon sequestration by 86 percent, and reduce the emission of volatile compounds by 88 percent." 12-06 Arguments for Caution When Using Trees for Carbon Sequestration (Mongabay.com) "Overall, about 20 percent more of the water provided by precipitation was removed by current tree farming, the study estimated. And additional planting of trees for carbon mitigation will likely have large impacts on water resources of many nations that net less than 30 percent of what precipitation provides for their total annual supplies of fresh water, the authors predicted." 07-08 Basics of Carbon Sequestration (EPA.gov) "There are three general means by which agricultural and forestry practices can reduce greenhouse gases:" "(1) avoiding emissions by maintaining existing carbon storage in trees and soils;" "(2) increasing carbon storage by, e.g., tree planting, conversion from conventional to conservation tillage practices on agricultural lands;" "(3) substituting bio-based fuels and products for fossil fuels, such as coal and oil, and energy-intensive products that generate greater quantities of CO2 when used." "Forests and soils have a large influence on atmospheric levels of carbon dioxide (CO2)—the most important global warming gas emitted by human activities. Tropical deforestation is responsible for about 20% of the world's annual CO2 emissions (IPCC Special Report on LULUCF (2000)." 07-08 Problems With Liquid Compressed Carbon Sequestration (TreeHugger.com) "In principle, it works this way: You capture CO2 emissions at the source before they are released into the atmosphere, compress them until they become liquid and then inject them in deep underground holes." 07-08 Seeding Oceans with Iron to Reduce Carbon Dioxide (Mongabay.com) " 'This iron deposition stimulates the ocean algae to convert carbon dioxide into organic carbon that may sink to ocean depths, potentially influencing the atmospheric carbon dioxide concentration,' according to a statement from Science." 07-08 WWF Against Seeding Oceans with Iron to Reduce Carbon Dioxide (Mongabay.com) "WWF says that the Planktos experiment could have unanticipated effects on plankton, which serve as the base of the marine food chain. The changes could ripple through the food chance to impact other species." "The group says that any bloom of phytoplankton induced by Planktos would be accompanied by a bloom in bacteria as phytoplankton die. These bacteria may produce gases--like nitrous oxide, a powerful greenhouse gas--that counteract the effects of carbon sequestration by phytoplankton. Further, bacterial decay consumes oxygen, which alters water chemistry." 07-08 Papers Algae for Natural Carbon Sequestration (ScienceDaily.com) "Engineers have designed a simple, sustainable and natural carbon sequestration solution using algae." "Bayless, with a team at Ohio University, created a photo bioreactor that uses photosynthesis to grow algae just like a plant would take carbon dioxide up and, through the energy of the sun, convert that into oxygen." "But what makes it cost effective? The algae can be harvested and made into biodiesel fuel and feed for animals." 06-08 Phosphorous Fosters Algae Growth (Canada.com) " 'Phosphorous really is the key to eutrophication,' says Schindler, whose study is highlighted prominently in the U.S. based Proceedings of the National Academy of Sciences this week." 07-08 The Need for Carbon Sequestration of Coal-Fired Energy Plants (CNN News) "Burning coal contributes half of the excess carbon dioxide (CO2) polluting the earth's atmosphere, a statistic not lost on the hundreds of climate change protesters camping in a grassy field near Kingsnorth power station in Kent, England this week." 08-08
