Geoengineering Research Needs Better Guidelines, Climate Change Experts Say

Huffington Post: With no clear rules to guide new research, scientists are shying away from examining whether geoengineering technologies can effectively cool the planet, and at what cost. Thats the warning put forth by a pair of climate change experts in an essay published Thursday in the journal Science. This deadlock poses real threats to sound management of climate risk, write Harvard University climate scientist David Keith and UCLA environmental law expert Edward Parson. Geoengineering may be needed...

Harvard professor argues geoengineering needs oversight

Boston Globe: Large-scale projects that could temper or reverse the effects of climate change by blocking some incoming sunlight or manipulating the atmosphere have long been unpopular on two opposing fronts. On one side are those worried about the unintended consequences and doomsday scenarios that could be set off by careless experiments. On the other are those who believe such research is important, but to support it now will detract from the urgent need to cut greenhouse gas emissions that are driving global...

Geoengineering by coalition to mitigate global warming

ScienceDaily: Solar geoengineering is a proposed approach to reduce the effects of climate change due to greenhouse gasses by deflecting some of the sun's incoming radiation. This type of proposed solution carries with it a number of uncertainties, however, including geopolitical questions about who would be in charge of the activity and its goals. New modeling work from Carnegie's Katharine Ricke and Ken Caldeira shows that if a powerful coalition ever decided to deploy a geoengineering system, they would...

Scientists dismiss geo-engineering as a global warming quick fix

Smithsonian: Installing a giant mirror in space to block sunlight, dispersing mass quantities of minerals into the oceans to suck carbon dioxide from the air and infusing the Earths upper atmosphere with sun-reflecting chemicals might sound like the stuff of science fiction, but theyre actual techniques that have been contemplated by scientists as possible quick solutions to climate change. More specifically, theyre examples of geo-engineering, a hotly contested subset of climate science whereby the Earths...
