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.“

„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[nbsp]emissions.“
„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.“
„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.“

„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.„
„“Climate engineering can be a way to build a better world,” said Katharine Mach, a senior research scientist at Stanford University during a recent virtual workshop on the promises and pitfalls of climate engineering held by the Institute on Science for Global Policy, in partnership with the Forum for Climate Geoengineering Assessment at American University, and the School of Sustainability at Arizona State University.“

„Last week, the Carbon Engineering team demonstrated “Air to Fuels” by directly synthesizing a mixture of gasoline and diesel using only CO2 captured from the air and hydrogen split from water with clean electricity.“
