Bulletin of the Atomic Scientists: The trouble with geoengineers “hacking the planet”

"Harvard crosses the Rubicon. But what has really catapulted the idea into the public eye is Harvard’s reckless plan for a privately-funded field trial testing some of the key elements needed for albedo modification"

MPR News: Should we geoengineer the atmosphere to fix climate change?

"But any kind of geoengineering raises serious logistical, ethical and geopolitical questions. In this week's Friday Roundtable, MPR News host Kerri Miller talks to three experts about the future possibilities of dealing with climate change."

Wood, Robert; et al. (2017): Could geoengineering research help answer one of the biggest questions in climate science?

Wood, Robert; Ackerman, Thomas; Rasch, Philip; Wanser, Kelly (2017): Could geoengineering research help answer one of the biggest questions in climate science? In: Earth's Future. DOI: 10.1002/2017EF000601.

"Observational studies show influences of aerosol on clouds, but correlations between aerosol and clouds are insufficient to constrain aerosol forcing because of the difficulty in separating aerosol and meteorological impacts. In this commentary, we argue that this current impasse may be overcome with the development of approaches to conduct control experiments whereby aerosol particle perturbations can be introduced into patches of marine low clouds in a systematic manner. Such cloud perturbation experiments constitute a fresh approach to climate science and would provide unprecedented data to untangle the effects of aerosol particles on cloud microphysics and the resulting reflection of solar radiation by clouds."

The National UEA: Sunny outlook for rain-inducing cloud seeding, researchers forecast

"In Britain, projects have analysed whether cloud seeding could help to lower the temperatures of the sea surface, which could make hurricanes less powerful by starving them of energy. Perhaps more outlandish is the suggestion that cloud seeding could limit global warming. Among those interested in producing clouds that could reflect sunlight is Stephen Salter, emeritus professor of engineering design at the University of Edinburgh."

Zelli, Fariborz; et al. (2017): Institutional complexity and private authority in global climate governance. The cases of climate engineering, REDD+ and short-lived climate pollutants

Zelli, Fariborz; Möller, Ina; van Asselt, Harro (2017): Institutional complexity and private authority in global climate governance. The cases of climate engineering, REDD+ and short-lived climate pollutants. In: Environmental Politics 26 (4), S. 669–693. DOI: 10.1080/09644016.2017.1319020 

"How and why do institutional architectures, and the roles of private institutions therein, differ across separate areas of climate governance? Here, institutional complexity is explained in terms of the problem-structural characteristics of an issue area and the associated demand for, and supply of, private authority. These characteristics can help explain the degree of centrality of intergovernmental institutions, as well as the distribution of governance functions between these and private governance institutions. This framework is applied to three emerging areas of climate governance: reducing emissions from deforestation and forest degradation (REDD+), short-lived climate pollutants (SLCPs), and climate engineering."

Power Mag: The Deep Dispute over “Deep Decarbonization”

"It began as an academic argument over how the world could meet a goal of 90% reductions in carbon dioxide emissions by 2050, known as “deep decarbonization.” Underneath the academic language is a fight among renewable energy advocates on the one hand and defenders of a role for conventional generating technologies, particularly nuclear, on the other. [...] Nevertheless, the daunting task of deep decarbonization could lead to climate engineering if the world definitively determines that a 2-degree-Celsius rise in global temperatures is an existential threat to the planet."
