Rahman, A. Atiq; et al. (2018): Developing countries must lead on solar geoengineering research

Rahman, A. Atiq; Artaxo, Paulo; Asrat, Asfawossen; Parker, Andy (2018): Developing countries must lead on solar geoengineering research. In Nature 556 (7699), pp. 22–24. DOI: 10.1038/d41586-018-03917-8.

"The nations that are most vulnerable to climate change must drive discussions of modelling, ethics and governance, argue A. Atiq Rahman, Paulo Artaxo, Asfawossen Asrat, Andy Parker and 8 co-signatories."

Frumhoff, Peter C.; Stephens, Jennie C. (2018): Towards legitimacy of the solar geoengineering research enterprise

Frumhoff, Peter C.; Stephens, Jennie C. (2018): Towards legitimacy of the solar geoengineering research enterprise. In Phil. Trans. R. Soc. A 376 (2119), p. 20160459. DOI: 10.1098/rsta.2016.0459.

"Here, we explore whether and how a solar geoengineering research enterprise might be developed in a way that promotes legitimacy as well as scientific credibility and policy relevance. We highlight the distinctive responsibilities of researchers and research funders to ensure that solar geoengineering research proposals are subject to legitimate societal review and scrutiny, recommend steps they can take to strive towards legitimacy and call on them to be explicitly open to multiple potential outcomes, including the societal rejection or considerable alteration of the solar geoengineering research enterprise."

MacMartin, Douglas G.; et al. (2018): Solar geoengineering as part of an overall strategy for meeting the 1.5°C Paris target

MacMartin, Douglas G.; Ricke, Katharine L.; Keith, David W. (2018): Solar geoengineering as part of an overall strategy for meeting the 1.5°C Paris target. In Phil. Trans. R. Soc. A 376 (2119), p. 20160454. DOI: 10.1098/rsta.2016.0454.

"We first provide a physical science review of current research, research trends and some of the key gaps in knowledge that would need to be addressed to support informed decisions. Next, since few climate model simulations have considered these limited-deployment scenarios, we synthesize prior results to assess the projected response if solar geoengineering were used to limit global mean temperature to 1.5°C above preindustrial in an overshoot scenario that would otherwise peak near 3°C. While there are some important differences, the resulting climate is closer in many respects to a climate where the 1.5°C target is achieved through mitigation alone than either is to the 3◦C climate with no geoengineering. This holds for both regional temperature and precipitation changes; indeed, there are no regions where a majority of models project that this moderate level of geoengineering would produce a statistically significant shift in precipitation further away from preindustrial levels."

geek.com: Throwing Salt Into the Atmosphere Might Help With Climate Change

"A group of scientists has suggested that dumping tremendous amounts of salt into the upper atmosphere could help lessen the effects of climate change. Quite similar to the sulfur dioxide plan we wrote about last year, the ploy would be based on the idea that salt particles can deflect some light, helping cool the other."

Wang, Qin; et al. (2018): A statistical examination of the effects of stratospheric sulphate geoengineering on tropical storm genesis

Wang, Qin; Moore, John C.; Ji, Duoying (2018): A statistical examination of the effects of stratospheric sulphate geoengineering on tropical storm genesis. In Atmos. Chem. Phys. Discuss., pp. 1–44. DOI: 10.5194/acp-2018-142.

"Here we use six CMIP5 models that have run the RCP4.5 experiment and the Geoengineering Model Intercomparison Project (GeoMIP) stratospheric aerosol injection G4 experiment, to calculate the two TC indices over the 2020 to 2069 period across the 6 ocean basins that generate tropical cyclones. Globally, GPI under G4 is lower than under RCP4.5, though both have a slight increasing trend. Spatial patterns in the effectiveness of geoengineering show reductions in TC in the North Atlantic basin, and Northern Indian Ocean in all models except NorESM1-M."

McKinnon, Catriona (2018): Sleepwalking into lock-in? Avoiding wrongs to future people in the governance of solar radiation management research

McKinnon, Catriona (2018): Sleepwalking into lock-in? Avoiding wrongs to future people in the governance of solar radiation management research. In Environmental Politics 118 (17), pp. 1–19. DOI: 10.1080/09644016.2018.1450344.

"Arguments are advanced for two ways in which we can avoid the reckless endangerment of future people in the governance of solar radiation management (SRM) research, which could happen through lock-in to SRM deployment from research. SRM research is at an early stage, one at which the mechanisms of lock-in could start to operate. However, lock-in fit to endanger future people could be slowed or stopped through targeted governance. Governance of SRM research that does not include provisions to detect, slow, or stop lock-in fails the test of an intergenerationally adequate precautionary principle, and research governed without these provisions cannot itself be justified as a precaution against the impacts of climate change."

Daily Mail: A solution to climate change? Scientists reveal controversial plan to sprinkle SALT into the sky to reflect the sun's rays and slow global warming

"The bizarre concept is based on the similar cooling effect of volcano eruptions on the atmosphere. However, such geoengineering plans are not without controversy. Some scientists warn artificially cooling Earth to counter global warming could destroy our planet if the process is abruptly stopped."

Clean Technica: Geoengineering — Reducing The Power Of Hurricanes With Curtains Of Air Bubbles

"There are those who say we can “science our way out” of climate change. Many of us are skeptical of such claims because we don’t know what the consequences of fiddling with the environment might be. Scientists at SINTEF, the The Foundation for Scientific and Industrial Research in Trondheim, Norway, have an idea for how to prevent hurricanes from forming or reducing the power of those that do form. The secret? Air bubbles."
