Singh, Jyoti; et al. (2020): Can stratospheric geoengineering alleviate global warming-induced changes in deciduous fruit cultivation? The case of Himachal Pradesh (India)

Singh, Jyoti; Sahany, Sandeep; Robock, Alan (2020): Can stratospheric geoengineering alleviate global warming-induced changes in deciduous fruit cultivation? The case of Himachal Pradesh (India). In Climatic Change. DOI: 10.1007/s10584-020-02786-3.

"Using Hadley Global Environment Model 2 - Earth System and Max Planck Institute Earth System Model simulations, we assess the impact of global warming and stratospheric geoengineering on deciduous fruit production in Himachal Pradesh (the second-largest apple-producing state in India). The impacts have been assessed for the Representative Concentration Pathways 4.5 (RCP4.5) global warming scenario, and a corresponding geoengineered scenario (G3) from the Geoengineering Model Intercomparison Project, in which stratospheric aerosols are increased for 50 years from 2020 through 2069 to balance the global warming radiative forcing, and then aerosol precursor emissions are terminated."

Wagner, Gernot; and Daniel Zizzamia (2020): Green Moral Hazards

Wagner, Gernot; and Daniel Zizzamia (2020): Green Moral Hazards. NYU Wagner Research Paper (8 July 2020). Working draft.

"We here explore green moral hazards throughout American history. We argue that dismissing (solar) geoengineering on moral hazard grounds is often unproductive. Instead, especially those vehemently opposed to the technology should use it as an opportunity to expand the attention paid to the underlying environmental problem in the first place, actively invoking its opposite: ‘inverse moral hazards’."

Beerling, David J.; et al. (2020): Potential for large-scale CO2 removal via enhanced rock weathering with croplands

Beerling, David J.; Kantzas, Euripides P.; Lomas, Mark R.; Wade, Peter; Eufrasio, Rafael M.; Renforth, Phil et al. (2020): Potential for large-scale CO2 removal via enhanced rock weathering with croplands. In Nature 583 (7815), pp. 242–248. DOI: 10.1038/s41586-020-2448-9.

"Here we use an integrated performance modelling approach to make an initial techno-economic assessment for 2050, quantifying how CDR potential and costs vary among nations in relation to business-as-usual energy policies and policies consistent with limiting future warming to 2 degrees Celsius."

Noah McQueen; et al. (2020): Ambient weathering of magnesium oxide for CO 2 removal from air

Noah McQueen; Peter Kelemen; Greg Dipple; Phil Renforth; Jennifer Wilcox (2020): Ambient weathering of magnesium oxide for CO 2 removal from air. In Nat Commun 11. DOI: 10.1038/s41467-020-16510-3.

"Here we detail a land-based enhanced weathering cycle utilizing magnesite (MgCO3) feedstock to repeatedly capture CO2 from the atmosphere. In this process, MgCO3 is calcined, producing caustic magnesia (MgO) and high-purity CO2."

Barben, Daniel; Matzner, Nils (2020): Anticipatory Governance of Climate Engineering

Barben, Daniel; Matzner, Nils (2020): Anticipatory Governance of Climate Engineering. In Oxford Research Encyclopedias: Geoengineering. DOI: 10.1093/acrefore/9780190228620.013.69.

"This article will discuss notions of anticipatory governance as developed in various institutional contexts concerned with assessing, funding, regulating, or conducting research and innovation. It will explore how notions of anticipatory governance have been transferred to the field of CE, in attempts at either shaping the course of CE-related research and innovation or at critically observing various CE-related governance endeavors by evaluating their capacities in anticipatorily governing research and technology development."

Geden, Oliver; Schenuit, Felix (2020): Unconventional mitigation. Carbon Dioxide Removal as a New Approach in EU Climate Policy

Geden, Oliver; Schenuit, Felix (2020): Unconventional mitigation. Carbon Dioxide Removal as a New Approach in EU Climate Policy. SWP Research Paper 2020/RP 08, June 2020. Stiftung Wissenschaft und Politik. doi:10.18449/2020RP08.

"If the EU wants to achieve net zero emissions by 2050, enacting conventional climate change mitigation measures to avoid emissions of greenhouse gases will not be enough. To compensate for unavoidable residual emissions, unconventional measures to remove CO2 from the atmosphere will also be necessary – for example, through afforestation or the direct cap­ture of CO2 from ambient air."

Donnison, Caspar; et al. (2020): Bioenergy with Carbon Capture and Storage (BECCS): Finding the win–wins for energy, negative emissions and ecosystem services—size matters

Donnison, Caspar; Holland, Robert A.; Hastings, Astley; Armstrong, Lindsay‐Marie; Eigenbrod, Felix; Taylor, Gail (2020): Bioenergy with Carbon Capture and Storage (BECCS): Finding the win–wins for energy, negative emissions and ecosystem services—size matters. In GCB Bioenergy. DOI: 10.1111/gcbb.12695.

"Bioenergy with Carbon Capture and Storage (BECCS) features heavily in the energy scenarios designed to meet the Paris Agreement targets, but the models used to generate these scenarios do not address environmental and social implications of BECCS at the regional scale. We integrate ecosystem service values into a land‐use optimization tool to determine the favourability of six potential UK locations for a 500 MW BECCS power plant operating on local biomass resources."

Sapinski, J. P.; et al. (2020): Has it come to this? The promises and perils of geoengineering on the brink

Sapinski, J. P.; Buck, Holly Jean; Malm, Andreas (Eds.) (2020): Has it come to this? The promises and perils of geoengineering on the brink. New Brunswick, Camden: Rutgers University Press (Nature, society, and culture).

"How did we get into this situation where the most extreme path now seems a plausible development? Is it an accurate representation of where we are at? Who is this “we” who is talking? What options make it onto the table? Which are left out? Whom does geoengineering serve? Why is the ensemble of projects that goes by that name so salient, even though the community of researchers and advocates is remarkably small? These are some of the questions that the thinkers contributing to this volume are exploring from perspectives ranging from sociology and geography to ethics and indigenous studies."
