TEDx: We can control climate, but should we? The ethics of geoengineering

"More specifically, the talk focuses on Marine Cloud Brightening, an idea that explores the possibility of "brightening" clouds over the ocean to make them reflect more sunlight away from the Earth. David then encourages the audience to consider the implications of such a drastic and far-reaching solution to global warming, and whether we, as humans, have the right to intentionally perturb our Earth's natural climate systems."

Climate Wire: Comity at first, then inaction on geoengineering

"Democrats and Republicans asked thoughtful questions on climate change, they weighed the concerns and costs of doing nothing and agreed more research for geoengineering was necessary."

Oceans Deeply: Scientists Warily Look to Geoengineering to Stave Off Polar Catastrophe

"From building barriers to buttress unstable marine ice sheets to thickening sea ice with a wind-powered pump, researchers want to start more conversations about climate interventions that don’t depend on actually cutting greenhouse gas emissions."

C2G2: Video/Audio: Communicating Geoengineering

"C2G2 encourages a broad societal debate on geoengineering, and strives to include a diversity of views and approaches in its events. This may sometimes lead to interventions being contested. C2G2 does not necessarily endorse or support the opinions stated by its presenters, and welcomes an open discussion of their merits."

Call for Papers: Open Questions in STS and Geoengineering (EASST conference)

Deadline: 14. February 2018

"A strong body of STS scholarship has begun to question the speculative and controversial proposal that geoengineering Earth's climate might be a good idea. This panel aims at exploring areas of inquiry that STS is yet to tackle."

Niemeier, Ulrike; Schmidt, Hauke (2017): Changing transport processes in the stratosphere by radiative heating of sulfate aerosols

Niemeier, Ulrike; Schmidt, Hauke (2017): Changing transport processes in the stratosphere by radiative heating of sulfate aerosols. In Atmos. Chem. Phys 17 (24), pp. 14871–14886. DOI: 10.5194/acp-17-14871-2017.

"The injection of sulfur dioxide (SO2) into the stratosphere to form an artificial stratospheric aerosol layer is discussed as an option for solar radiation management. Sulfate aerosol scatters solar radiation and absorbs infrared radiation, which warms the stratospheric sulfur layer. Simulations with the general circulation model ECHAM5-HAM, including aerosol microphysics, show consequences of this warming, including changes of the quasi-biennial oscillation (QBO) in the tropics. The QBO slows down after an injection of 4 Tg(S) yr−1 and completely shuts down after an injection of 8 Tg(S) yr−1."
