Malm, Andreas; Carton, Wim (2021): Seize the Means of Carbon Removal: The Political Economy of Direct Air Capture

Malm, Andreas; Carton, Wim (2021): Seize the Means of Carbon Removal: The Political Economy of Direct Air Capture. In Hist. Mater., pp. 1–46. DOI: 10.1163/1569206X-29012021.

"The left must confront the politics of removing carbon from the atmosphere – a topic rapidly making its way to the top of the climate agenda. We here examine the technology of direct air capture, tracing its intellectual origins and laying bare the political economy of its current manifestations."

Corbett, Charles R. (2021): “Extraordinary” and “Highly Controversial”: Federal Research of Solar Geoengineering Under NEPA

Corbett, Charles R. (2021): “Extraordinary” and “Highly Controversial”: Federal Research of Solar Geoengineering Under NEPA. In Nw. U. L. Rev. Online 115 (240). Available online at https://scholarlycommons.law.northwestern.edu/cgi/viewcontent.cgi?article=1307&context=nulr_online&fbclid=IwAR0kQGReczRbpsuRrn1WgZnh5QI2QwEsULw5irDYt1fBz-cCKoN6vtMY-as.

"Congress recently instructed the National Oceanic and Atmospheric Administration (NOAA) to investigate stratospheric aerosols, materials that could be injected in the atmosphere as a means of solar climate intervention. This action has been widely interpreted as the first-ever federal research project into solar geoengineering—proposals to slightly “dim the sun” to limit the harms of climate change. This Essay argues that NOAA should use its discretion to conduct a programmatic environmental assessment under the National Environmental Policy Act (NEPA) as an initial step in governing this research program."

Jiang, Yuan; et al. (2021): Techno-economic comparison of various process configurations for post-combustion carbon capture using a single-component water-lean solvent

Jiang, Yuan; Mathias, Paul M.; Freeman, Charles J.; Swisher, Joseph A.; Zheng, Richard F.; Whyatt, Greg A.; Heldebrant, David J. (2021): Techno-economic comparison of various process configurations for post-combustion carbon capture using a single-component water-lean solvent. In International Journal of Greenhouse Gas Control 106, p. 103279. DOI: 10.1016/j.ijggc.2021.103279.

"Even though advanced process configurations have been intensively studied for aqueous amines, few discussions can be found in the open literature for water-lean solvents. In order to fill the gap, the present study focuses on the process designs towards lower carbon capture cost enabled by water-lean solvents."

Visioni, Daniele; et al. (2021): Identifying the sources of uncertainty in climate model simulations of solar radiation modification with the G6sulfur and G6solar Geoengineering Model Intercomparison Project (GeoMIP) simulations

Visioni, Daniele; MacMartin, Douglas G.; Kravitz, Ben; Boucher, Olivier; Jones, Andy; Lurton, Thibaut et al. (2021): Identifying the sources of uncertainty in climate model simulations of solar radiation modification with the G6sulfur and G6solar Geoengineering Model Intercomparison Project (GeoMIP) simulations. Preprint. In Atmos. Chem. Phys. DOI: 10.5194/acp-2021-133.

"We present here results from the Geoengineering Model Intercomparison Project (GeoMIP) simulations for the experiment G6sulfur and G6solar for six Earth System Models participating in the Climate Model Intercomparison Project (CMIP) Phase 6. The aim of the experiments is to reduce the warming from that resulting from a high-tier emission scenario (Shared Socioeconomic Pathways SSP5-8.5) to that resulting from a medium-tier emission scenario (SSP2-4.5)."

Liu, Jiaojiao; Shi, Xiangjun (2021): Estimating the potential cooling effect of cirrus thinning achieved via the seeding approach

Liu, Jiaojiao; Shi, Xiangjun (2021): Estimating the potential cooling effect of cirrus thinning achieved via the seeding approach. Preprint. In Atmos. Chem. Phys. DOI: 10.5194/acp-2021-148.

"A simulation using the Community Atmosphere Model version 5 (CAM5) with the flexible seeding method shows a global cooling effect of 1.36 ± 0.18 W m−2, which is approximately two-thirds of that from artificially turning off homogeneous nucleation (−1.98 ± 0.26 W m−2)."

Peoples, Columba (2021): Global uncertainties, geoengineering and the technopolitics of planetary crisis management

Peoples, Columba (2021): Global uncertainties, geoengineering and the technopolitics of planetary crisis management. In Globalizations, pp. 1–15. DOI: 10.1080/14747731.2021.1882815.

"With rising sea levels and disappearing species as harbingers of a planet-wide existential crisis facing the Earth, this article considers the ways in which geoengineering proposals diverge from understandings of global uncertainties and threats within scholarship on the globalization of insecurity, instead identifying ‘the planetary’ as a distinctive space of insecurity."

Schenuit, Felix; et al. (2021): Carbon Dioxide Removal Policy in the Making: Assessing Developments in 9 OECD Cases

Schenuit, Felix; Colvin, Rebecca; Fridahl, Mathias; Mcmullin, Barry; Reisinger, Andy; Sanchez, Daniel L. et al. (2021): Carbon Dioxide Removal Policy in the Making: Assessing Developments in 9 OECD Cases. In Front. Clim. 3. DOI: 10.3389/fclim.2021.638805.

"Based on an analytical framework that draws on the multi-level perspective of sociotechnical transitions as well as existing work on CDR governance, we gathered and assessed empirical material until early 2021 from 9 Organization for Economic Co-operation and Development (OECD) cases: the European Union and three of its Member States (Ireland, Germany, and Sweden), Norway, the United Kingdom, Australia, New Zealand, and the United States."
