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…

Ecosystem Translocation: The latest Climate Engineering Brainstorm

Guest essay by Eric Worrall Stéphane Boyer, senior lecturer at UNITEC Institute of Technology is worried that plants and animals can’t move fast enough to survive climate change. His solution: give nature a helping hand, by digging up entire ecosystems, and moving them hundreds of miles, to maintain optimum climatic conditions. Climate change threatens entire…

#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…
