MacMartin, D.; Kravitz, B. (2019): Mission-driven research for stratospheric aerosol geoengineering. In: Proceedings of the National Academy of Sciences of the United States of America. DOI: 10.1073/pnas.1811022116.

"The last decade has seen broad exploratory research into stratospheric aerosol (SA) geoengineering, motivated by concern that reducing greenhouse gas emissions may be insufficient to avoid significant impacts from climate change. [...] We highlight two important observations that follow from considering such a comprehensive, prioritized natural-science research effort. First, while field experiments may eventually be needed to reduce some of the uncertainties, we expect that the next phase of research will continue to be primarily model-based, with one outcome being to assess and prioritize which uncertainties need to be reduced (and, as a corollary, which field experiments can reduce those uncertainties). Second, we anticipate a clear separation in scale and character between small-scale experimental research to resolve specific process uncertainties and global-scale activities."

"In this paper, we articulate a series of key take‐home points. First, the potential amount of carbon an ecosystem can assimilate on an annual basis scales with absorbed sunlight, which varies with latitude, leaf area index and available water. [...] We based our analysis on 1163 site‐years of direct eddy covariance measurements of gross and net carbon fluxes from 155 sites across the globe."

"Ultramicroporous carbon materials play a critical role in CO₂ capture and separation, however facile approaches to design ultramicroporous carbon with controllable amount, ratio and size of pores are still challenging. [...] This work provides a novel and facile guideline to engineer carbon materials with abundant and tunable ultramicroporosity towards superior CO₂ capture performance, which also delivers great potential in extensive applications such as water purification, catalysis, and energy storage."

"We specifically assess differences in a range of near-term indicators describing CO2 emissions reductions pathways, changes in primary energy and final energy across the economy's major sectors, in addition to more detailed metrics around the use of carbon capture and storage (CCS), negative emissions, low-carbon electricity and hydrogen."
