Mongabay.com news articles on geoengineering in blog format. Updated regularly.
(4/24/2008) A proposed plan to fight global warming by injecting sulfate particles into Earth's upper atmosphere could damage the ozone layer over the Arctic and Antarctic, report researchers writing in the journal Science. Planktos kills iron fertilization project due to environmental opposition (2/19/2008) Planktos, a California-based firm that planned a controversial iron-fertilization scheme in an attempt to qualify carbon offsets, announced that it failed to find sufficient funding for its efforts and would postpone its project indefinitely. Too early to say if iron seeding will slow global warming - scientists (1/10/2008) Schemes to use feed the ocean with iron as a way to enhance carbon sequestration from the atmosphere are premature and could be damaging to sea life and marine ecosystems, warns a letter published in the journal Science by an international group of scientists. New research discredits a $100 billion geoengineering fix to global warming (11/29/2007) Scientists have revealed an important discovery that raises doubts concerning the viability of plans to fertilize the ocean to solve global warming, a projected $100 billion venture. Ocean CO2 collector could fight global warming and ocean acidification (11/19/2007) Researchers have proposed a geoengineering solution to global warming that involves building a series of water treatment plants that enhance the ability of the ocean to absorb carbon dioxide from the atmosphere by removing hydrochloric acid from seawater by electrolysis. Weathering technology could mitigate global warming (11/8/2007) Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide (CO2) caused by human emissions. Iron boosts carbon sequestration by the ocean (8/23/2007) Wind-blown iron contributes significantly to the biological productivity of the Southern Ocean near Antarctica, researchers report in this week's issue of the journal Science. Geoengineering cure for global warming could cause problems (8/14/2007) Proposed geoengineering schemes to reduce global warming may do more harm than good, warns a new study published in Geophysical Research Letters. WWF condemns iron fertilization scheme to fight global warming (6/28/2007) Environmental group WWF condemned a scheme by Planktos, Inc. (OTCBB: PLKT) to dump up to 100 tons of iron dust in the open ocean west of the Galapagos Islands. The firm claims the experiment will fertilize massive blooms of phytoplankton that will absorb carbon dioxide from the atmosphere and help fight global warming. Geoengineering could stop global warming but carries big risks (6/4/2007) Using radical techniques to ,engineer, Earth's climate by blocking sunlight could cool Earth but presents great risks that could well worsen global warming should they fail or be discontinued, reports a new study published in the June 4 early online edition of The Proceedings of the National Academy of Sciences. Modifying clouds to fight global warming (8/15/2005) An article in The Sunday Times reports that a scientist is working a cloud manufacturing technique to counter global warming.
