New save the planet scheme: 'cocktail geoengineering'

Could ‘cocktail geoengineering’ save the climate? From the CARNEGIE INSTITUTION FOR SCIENCE Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth’s energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical Research Lettersinvestigates for the first time the possibility of using a “cocktail”…

Limestone Dust: The Latest Climate Geoengineering Favourite

Guest essay by Eric Worrall A US study has suggested hurling crushed limestone into the stratosphere to halt global warming, on the grounds that it would do less damage than sulphates, and might help repair the ozone layer. Atmospheric limestone dust injection could halt global warming Geoengineering using limestone aerosols would also help to stop…

Study: The climate 'uncertainty monster' limits geoengineering schemes

From the VTT TECHNICAL RESEARCH CENTRE OF FINLAND, a paper that suggests Dr. Judith Curry’s view of the “uncertainty monster” was right all along. Uncertainties related to climate engineering limit its use in curbing climate change Climate engineering refers to the systematic, large-scale modification of the environment using various climate intervention techniques. However, a new study…

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…
