Carr, Wylie A.; Yung, Laurie (2018): Perceptions of climate engineering in the South Pacific, Sub-Saharan Africa, and North American Arctic

Carr, Wylie A.; Yung, Laurie (2018): Perceptions of climate engineering in the South Pacific, Sub-Saharan Africa, and North American Arctic. In Climatic Change 17 (2), p.[nbsp]145. DOI: 10.1007/s10584-018-2138-x.

„This study utilized in-depth interviews to explore the perspectives of vulnerable populations in the South Pacific, Sub-Saharan Africa, and the North American Arctic. Interviewees in this study were desperate for solutions to climate change and therefore willing to consider climate engineering. However, their willingness to consider climate engineering could be characterized as both deeply reluctant and highly conditional. „

Nova Next: Should We Intentionally Manipulate the Earth’s Climate?

„Carbon dioxide removal technologies like BECCS, which removes carbon dioxide from the atmosphere using plants as the collectors, are helpful—but may not be potent enough. A more controversial form of what scientists are calling geoengineering is called solar radiation management. This involves reflecting heat away from the Earth instead of siphoning it out of the atmosphere.“

Irvine, Peter J.; et al. (2018): Brief communication. Understanding solar geoengineerings potential to limit sea level rise requires attention from cryosphere experts

Irvine, Peter J.; Keith, David W.; Moore, John (2018): Brief communication. Understanding solar geoengineering’s potential to limit sea level rise requires attention from cryosphere experts. In The Cryosphere Discuss., pp.[nbsp]1–15. DOI: 10.5194/tc-2017-279.

Stratospheric aerosol geoengineering, a form of solar geoengineering, is a proposal to add a reflective layer of aerosol to the stratosphere to reduce net radiative forcing and so to reduce the risks of climate change. Solar geoengineering could reduce temperatures and so slow melt, but the efficacy of solar geoengineering at offsetting changes to the cryosphere is uncertain. For example, shortwave forcing acts more strongly on the surface than longwave forcing so solar geoengineering would reduce surface melt more effectively but would also suppress the global hydrological cycle potentially reducing accumulation on glaciers.

Sonntag, Sebastian; et al. (2018): Quantifying and comparing effects of climate engineering methods on the Earth system

Sonntag, Sebastian; González, Miriam Ferrer; Ilyina, Tatiana; Kracher, Daniela; Nabel, Julia E. M. S.; Niemeier, Ulrike et al. (2018): Quantifying and comparing effects of climate engineering methods on the Earth system. In Earth’s Future. DOI: 10.1002/2017EF000620.

„To contribute to a quantitative comparison of climate engineering (CE) methods, we assess atmosphere-, ocean-, and land-based CE measures with respect to Earth system effects consistently within one comprehensive model. We use the Max Planck Institute Earth System Model (MPI-ESM) with prognostic carbon cycle to compare solar radiation management (SRM) by stratospheric sulfur injection and two carbon dioxide removal methods: afforestation and ocean alkalinization. The CE model experiments are designed to offset the effect of fossil-fuel burning on global mean surface air temperature under the RCP8.5 scenario to follow or get closer to the RCP4.5 scenario.“

Nori Blog: Reversing climate change means carbon removal

For us, that means making it as easy as possible for volunteers who want to pay to fix the problem to be able to do so. Fixing the problem means making it possible to create a reverse gear that can take us back. The reverse gear is carbon removal. Here are[nbsp]five reasons why we are only focused on taking back CO2 from the air.

Stoy, Paul C.; et al. (2018): Opportunities and Trade-offs among BECCS and the Food, Water, Energy, Biodiversity, and Social Systems Nexus at Regional Scales

Stoy, Paul C.; Ahmed, Selena; Jarchow, Meghann; Rashford, Benjamin; Swanson, David; Albeke, Shannon et al. (2018): Opportunities and Trade-offs among BECCS and the Food, Water, Energy, Biodiversity, and Social Systems Nexus at Regional Scales. In BioScience 8, p.[nbsp]81. DOI: 10.1093/biosci/bix145.

„Here, we present an interdisciplinary research framework to examine the trade-offs as well as the opportunities among BECCS scenarios and FWEBS on regional scales using the Upper Missouri River Basin (UMRB) as a case study. We describe the physical, biological, and social attributes of the UMRB, and we use grassland bird populations as an example of how biodiversity is influenced by energy transitions, including BECCS. We then outline a “conservation” BECCS strategy that incorporates societal values and emphasizes biodiversity conservation.“
