Stuart, G. S.; et al. (2013): Reduced efficacy of marine cloud brightening geoengineering due to in-plume aerosol coagulation: parameterization and global implications

Stuart, G. S.; Stevens, R. G.; Partanen, A.-I.; Jenkins, A. K. L.; Korhonen, H.; Forster, P. M. et al. (2013): Reduced efficacy of marine cloud brightening geoengineering due to in-plume aerosol coagulation: parameterization and global implications. In Atmos. Chem. Phys. 13 (20), pp.[nbsp]10385–10396. DOI: 10.5194/acp-13-10385-2013.

On marine cloud brightening. “We explore the evolution of these sea-salt plumes using a multi-shelled Gaussian plume model with size-resolved aerosol coagulation. We determine how the final number of particles depends on meteorological conditions, including wind speed and boundary-layer stability, as well as the emission rate and size distribution of aerosol emitted.

Yale Cultural Cognition Project: Weekend update: geoengineering and the expanding confabulation frontier of the “climate communication” debate

“Despite its astonishingly long run in grounding just-so story telling about public risk perceptions and science communication (e.g., the Rasputin “bounded rationality” account of public apathy), the “climate debate” at some point has to get the benefit of an infusion of new material or else the players will ultimately die out from terminal boredom. That’s the real potential, of course, of geoengineering.”

Nautilus: An Astrobiologist Asks a Sci-fi Novelist How to Survive the Anthropocene

On the antropocene and not directly on CE. “Humans will have a chance to prove their adaptability as the Earth undergoes unprecedented challenges in the Anthropocene, an era named after our impact on the biosphere. To learn what it takes to survive far into the future, astrobiologist David Grinspoon interviewed Kim Stanley Robinson, a writer regarded as one of the most important science fiction and political novelists alive today.”

Reynolds, Jesse (2014): A Critical Examination of the Climate Engineering Moral Hazard and Risk Compensation Concern

Reynolds, Jesse (2014): A Critical Examination of the Climate Engineering Moral Hazard and Risk Compensation Concern. European Consortium for Political Research General Conference. Glasgow, 9/5/2014.

Presentation manuscript. “If the goal of climate policy is to minimize climate risks, this concern should not be grounds for restricting or prohibiting climate engineering research. Three potential means for this concern to manifest in genuinely deleterious ways, as well as policy options to reduce these effects, are identified.”

Petersen, Arthur C. (2014): The Emergence of the Geoengineering Debate Within The IPCC (Case Study)

Petersen, Arthur C. (2014): The Emergence of the Geoengineering Debate Within The IPCC (Case Study) (Geoengineering Our Climate? Working Paper and Opinion Article Series).

“Firstly, the IPCC has a long history of dealing with geoengineering and, secondly, the IPCC performs its assessments[nbsp] without endorsing any options and being based on what is available in the primary literature. Still, there is no way to deny that the way the IPCC summarises the science does have an influence on how a particular subject is subsequently discussed in policy-making.”
