Dissent: The Climate Hackers

„The final—and most dangerous—characteristic of the pro-geoengineering argument is that it imagines that this technology could operate in a political void. Keith’s inviting opening sentence about solar radiation being a plausible scenario for reducing climate risk finishes with a crucial qualifier: “in a world without politics.”“

Wiertz, Thilo (2015): Visions of Climate Control. Solar Radiation Management in Climate Simulations. In Science, Technology [&] Human Values. DOI: 10.1177/0162243915606524[nbsp]

„Considering insights from social studies of simulation modeling and research on expectations in science and technology, I argue that climate modeling has a central role in producing visions of SRM. I draw upon an empirical analysis of scientific research on SRM to examine how a creative play with technological ideas becomes possible through climate modeling.“

Glienke, Susanne; et al. (2015): The impact of geoengineering on vegetation in experiment G1 of the Geoengineering Model Intercomparison Project (GeoMIP)

Glienke, Susanne; Irvine, Peter J.; Lawrence, Mark G. (2015): The impact of geoengineering on vegetation in experiment G1 of the Geoengineering Model Intercomparison Project (GeoMIP). In J. Geophys. Res. Atmos., pp.[nbsp]n/a-n/a. DOI: 10.1002/2015JD024202

„Thus far, the effects on vegetation have not yet been thoroughly analyzed. Here, the vegetation response to the idealized GeoMIP G1 experiment from eight fully coupled earth system models (ESMs) is analyzed, in which a reduction of the solar constant counterbalances the radiative effects of quadrupled atmospheric CO2 concentrations (abrupt4xCO2).“

Xia, Lili; et al. (2015): Stratospheric sulfate geoengineering enhances terrestrial gross primary productivity

Xia, Lili; Robock, Alan; Tilmes, Simone; Neely, R. R. (2015): Stratospheric sulfate geoengineering enhances terrestrial gross primary productivity. In Atmos. Chem. Phys. Discuss. 15 (18), pp.[nbsp]25627–25645. DOI: 10.5194/acpd-15-25627-2015[nbsp]

Stratospheric sulfate geoengineering could impact the terrestrial carbon cycle by enhancing the carbon sink. With an 8 Tg yr−1 injection of SO2 to balance a Representative Concentration Pathway 6.0 (RCP6.0) scenario, we conducted climate model simulations with the Community Earth System Model, with the Community Atmospheric Model 4 fully coupled to tropospheric and stratospheric chemistry (CAM4-chem).

The Center for Carbon Removal: Reduce, recycle, remove: what waste management can teach us about controlling carbon emissions

„Each year, the world produces around ten billion tons of trash. A significant portion of this trash ends up as litter, polluting our cities, water, and ecosystems, and resulting in significant costs to the environment and society. In response, society deploys a three-pronged strategy to fight litter: 1) reduce waste production, 2) recycle as much of the remaining waste as possible, and 3) remove the rest in sealed landfills that protect the environment from the consequences of this pollution.“

„This chapter argues that the psychological dynamics of creative and disintegrative ‚ego breakdown‘ in the face of threatiening problems and the flux of the world, can elucidate social responses to the problem of climate change. The climate problems present a collective (although not uniformly distributed) set of challenges to some habitual ego forms and culture complexes and are processed with difficulty within them.“

Gaps in the governance of this scientific research still remain.[nbsp]To remedy these issues, this brief recommends that the International Maritime Organization and parties to the LC-LP develop memorandums of understanding to delineate framework implementation plans, adopt legally binding governance transparency mechanisms to ensure linkages between national and international governance institutions, and create independent assessment panels.“

Maruyama, Shigenao; et al. (2015): Possibility for controlling global warming by launching nanoparticles into the stratosphere

„The objective of the present work is to examine the first-order approximation of the feasibility of controlling the global temperature without reducing the emission of greenhouse gases. We propose the controlled dispersion of nanoparticles into the stratosphere at an altitude of 30 km.“
