Geo-engineering to combat climate change gets negative public response

United Press International: Geo-engineering -- deliberate manipulation of the environment to counter climate change -- does not find favor with most of the public, a British study found. That's the report of researchers from the University of Southampton, writing in the journal Nature Climate Change. Working with colleagues at Massey University in New Zealand, they undertook the first systematic large-scale evaluation of public reaction to climate engineering. Some scientists argue that climate engineering approaches...

The pros and cons of geoengineering

Living on Earth: In a bid to avoid some of the worst effects of climate change some scientists are advocating possible strategies to artificially alter the climate. But critics warn of unforeseen and dangerous consequences of any atmosphere altering intervention. David Keith from Harvard University and Clive Hamilton of Charles Sturt University in Australia debate the case for each side with host Steve Curwood. Transcript CURWOOD: It's Living on Earth, I'm Steve Curwood. Since we started farming in the Fertile...

Solar Geoengineering: Weighing Costs of Blocking the Suns Rays

Yale Environment 360: In 1991, Mount Pinatubo in the Philippines erupted in one of the largest volcanic blasts of the 20th century. It spat up to 20 million tons of sulfur into the upper atmosphere, shielding the earth from the suns rays and causing global temperatures to drop by nearly half a degree Celsius in a single year. Thats more than half of the amount the planet has warmed Studies have shown that such a strategy would be powerful, feasible, fast-acting, and cheap. due to climate change in 130 years. Now...

Geoengineering Earths Climate: Potential, Barriers And Ethics
2013-12-18 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Artificial clouds that reflect sunlight back into space. A StratoShield that spews sulfur dioxide particles into space like a volcano, cooling the planets surface. Microbial blooms that grow on iron injected into the ocean and trap carbon dioxide from the atmosphere. These are some of the latest ideas being tested to combat climate change in an emerging and hotly-debated field called geoengineering. Geoengineering involves use of technologies that deliberately manipulate the Earths climate,...

More evidence that geo-engineering is likely to have unintended consequences
2013-12-08 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit Voice: When it comes to global warming nothing is simple -- and that includes proposals to mitigate the effects of heat-trapping greenhouse gases with planetary scale geo-engineering schemes. One of the ideas that`s been floated is to seed the atmosphere with material in order to reflect some of the sun`s incoming heat. But a recent study by German researchers suggests that it probably won`t work -- and could have unexpected consequences for the global water cycle. In their model, based on an energy...
