Hacking (or quacking) the planet with geoengineering

Hack the planet? Geoengineering research, ethics, governance explored by Hannah Hickey Hacking the Earth’s climate to counteract global warming – a subject that elicits strong reactions from both sides – is the topic of a December special issue of the journal Climatic Change. A dozen research papers include the most detailed description yet of the…

Geoengineering approaches to reduce climate change unlikely to succeed

From the EGU: Heavy rainfall events can be more common in a warmer world (Credit: Annett Junginger, distributed via imaggeo.egu.eu) Reducing the amount of sunlight reaching the planet’s surface by geoengineering may not undo climate change after all. Two German researchers used a simple energy balance analysis to explain how the Earth’s water cycle responds…

Another geoengineering idea – gaming coalition modeled

From the Carnegie Institution  comes a nutty consensus type idea, modeled in game-theory, implemented by an equally nutty future coalition. Law of unintended consequences anyone? Geoengineering by coalition Washington, D.C.—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…

Sunshade geoengineering people apparently have been in the midday sun too long

From the Carnegie Institution , not just aerosol injections, but effective aersol injections. Law of unintended consequences be damned. Improving effectiveness of solar geoengineering Washington, D.C.— Solar radiation management is a type of geoengineering that would manipulate the climate in order to reduce the impact of global warming caused by greenhouse gasses. Ideas include increasing…

Ship sprayed seawater cloud making V2.0

Willis covered this before on WUWT, with Every Silver Lining Has A Cloud. Its baaaack. Figure 1. Artist’s conception of cloud-making ships. Of course, the first storm would flip this over immediately, but heck, it’s only a fantasy, so who cares? SOURCE From the University of Washington  and the Royal Society Experiment would test cloud geoengineering…

Green revolt against geoengineering – letter to Pachauri

WUWT readers may recall this story on geoengineering on WUWT that referred to at the time as “batshit crazy“. It seems others in the green community agree. This Open letter to IPCC on geoengineering has had over 100 signatories, many of them major environemnetal players and was sent to chairman Pachauri. Right now that seems…

Leaked: smoke and mirror geoengineering ideas from the IPCC

Must be IPCC week. When it rains the stupid, it pours.  From the Telegraph: IPCC ‘considering sending mirrors to space to tackle climate change’ Reflective aerosols would be sent into space under a series of radical “geo-engineering” measures being considered by the UN climate science body to tackle climate change, leaked documents disclose. The Intergovernmental…
