MIT study shows climate change mitigation potential of geoengineering oceans
2015-09-14 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl sulfide (DMS) into the atmosphere, where it forms sulfate aerosols, which can directly reflect sunlight or increase cloud cover and reflectivity, resulting in a cooling effect. The ability of phytoplankton...
Geoengineering will not save ocean life from acidification, research says
2015-08-06 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
InsideClimate: Waiting to tackle ocean acidification caused by climate change through yet-to-be developed geoengineering schemes will be too little too late to prevent mass extinction of ocean life, a new study concludes. Cutting carbon emissions is the only way for oceans to recover from the devastating effects of climate change, according to the new research published in Nature Climate Change. While using deliberate, large-scale manipulation of earth processes to combat global warming has its proponents, intervening...

World's biggest geoengineering experiment 'violates' UN rules
2015-03-05 04:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: A controversial American businessman dumped around 100 tonnes of iron sulphate into the Pacific Ocean as part of a geoengineering scheme off the west coast of Canada in July, a Guardian investigation can reveal. Lawyers, environmentalists and civil society groups are calling it a "blatant violation" of two international moratoria and the news is likely to spark outrage at a United Nations environmental summit taking place in India this week. Satellite images appear to confirm the claim by Californian...

Renewable energies deserve more attention geoengineering
2015-02-18 22:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Daily Orange: A Feb. 10 release from The National Academies explored the topic of climate intervention, also known as geoengineering. Geoengineering involves removing existing carbon dioxide from the atmosphere and reducing the amount of sunlight entering the atmosphere. Both tactics have the intention of reducing and potentially reversing the effects of human-caused climate change. Geoengineering is an exciting idea but it is equally dangerous, both physically and imaginatively. Physically, most forms of implementation...
