Song, Juzheng; et al. (2018): Quaternized Chitosan/PVA Aerogels for Reversible CO 2 Capture from Ambient Air

Song, Juzheng; Liu, Jie; Zhao, Wei; Chen, Yan; Xiao, Hang; Shi, Xiaoyang et al. (2018): Quaternized Chitosan/PVA Aerogels for Reversible CO 2 Capture from Ambient Air. In Ind. Eng. Chem. Res. DOI: 10.1021/acs.iecr.8b00064.

"Developing inexpensive and highly efficient CO2 air capture technologies is an important solution for solving the greenhouse problem. In this work, we used the low-cost quaternized chitosan (QCS)/poly(vinyl alcohol) (PVA) hybrid aerogels with quaternary ammonium groups and hydroxide ions to reversibly capture CO2 from ambient air by humidity swing."

Gerrard, Michael B.; Hester, Tracy (Eds.) (2018): Climate Engineering and the Law

Gerrard, Michael B.; Hester, Tracy (Eds.) (2018): Climate Engineering and the Law. Cambridge University Press.

"This is the first book to focus on the legal aspects of these technologies: what government approvals would be needed; how liability would be assessed and compensation provided if something goes wrong; and how a governance system could be structured and agreed internationally."

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."

Nori: Podcast with Noah Deich and Giana Amador of the Center for Carbon Removal

"Noah Deich and Giana Amador are the co-founders of CCR, a nonprofit working to halt climate change by restoring atmospheric CO2 concentrations to sustainable levels. Noah worked as a management consultant on clean energy and corporate sustainability projects before assuming his role as Executive Director of CCR, and he holds an MBA from the Haas School of Business at UC Berkeley. Giana’s background lies in the policy, technology and political economy of renewable energy in the US, and she received her BS in Environmental Economics and Policy as well as Society and the Environment at UC Berkeley before becoming the Managing Director of the organization."

Eco-Business: The IPCC leak: What do Chinese experts think?

"The 1.5C target would still require geoengineering to either remove greenhouse gases from the atmosphere, or artificially reduce the earth’s temperature. However, current geoengineering schemes such as deflecting solar radiation or storing carbon dioxide emissions underground, are untested at scale and may do more harm than good."

Live Science: These Scientists Have a Wild Plan to Throw Salt into the Atmosphere. Here's Why

"Sprinkling large amounts of salt into the atmosphere could stave off climate change, a group of researchers has proposed. They've suggested that, because salt is highly reflective, it could potentially reflect sunlight back into outer space, helping to cool the Earth, they wrote in a report presented at the Lunar and Planetary Science Conference in Texas on March 21."

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."
