Another geoengineering scheme plans to use planes and ships to cool the planet

From the UNIVERSITY OF EASTERN FINLAND, and the unexpected consequence of Geoengineering Department, comes this thesis from a grad student: Atmospheric aerosols can significantly cool down climate It is possible to significantly slow down and even temporarily stop the progression of global warming by increasing the atmospheric aerosol concentration, shows a new study from the…

US Senate Considering Albedo Modification Geoengineering Proposal

Guest essay by Eric Worrall The US Senate is considering funding for albedo modification geoengineering experiments – pumping particles or aerosols into the stratosphere, to reflect sunlight back into space, and counter the alleged impact of elevated CO2 levels on global climate. According to ScienceMag; To fight global warming, Senate calls for study of making…

#AGU15 Accidental Geoengineering? Airline traffic may help create an icy haze that’s brightening U.S. skies

SAN FRANCISCO, CALIFORNIA —The data just didn’t seem to make sense. That’s often the story right before scientists make a leap in understanding. In this case, scientists had some evidence that skies in the continental United States have been brightening, after several decades of so-called “dimming.” Brightening and dimming are overly simplified words that signify…

Nutty claim: Advent of geoengineering may help lower temperature of debate over climate change

From Yale University and the “we had to burn the village to save it” department: Geoengineering, an emerging technology aimed at counteracting the effects of human-caused climate change, also has the potential to counteract political polarization over global warming, according to a new study. Published Feb. 9 in the journal Annals of the American Academy…

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…

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…

Another nutty geoengineering idea – Olivine dust

From the Institute of Physics Researchers analyse ‘rock dissolving’ method of geoengineering The benefits and side effects of dissolving particles in our ocean’s surfaces to increase the marine uptake of carbon dioxide (CO2), and therefore reduce the excess amount of it in the atmosphere, have been analysed in a new study published today. The study,…

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…
