Dowell, Glen; et al. (2020): Rooting carbon dioxide removal research in the social sciences

Dowell, Glen; Niederdeppe, Jeff; Vanucchi, Jamie; Dogan, Timur; Donaghy, Kieran; Jacobson, Rory et al. (2020): Rooting carbon dioxide removal research in the social sciences. In Interface Focus. 10 (5), p. 20190138. DOI: 10.1098/rsfs.2019.0138.

"As the need for rapid, effective and successful CDR has only increased since that time, we argue that CDR researchers from across the spectrum must come together in ways that simultaneously address the technical, social, political, economic and cultural elements of CDR development, commercialization, adoption and diffusion if the academy is to have a material impact on climate change in the increasingly limited window we have to address it."

Jones, Andy; et al. (2020): North Atlantic Oscillation response in GeoMIP experiments G6solar and G6sulfur: why detailed modelling is needed for understanding regional implications of solar radiation management

Jones, Andy; Haywood, Jim M.; Jones, Anthony C.; Tilmes, Simone; Kravitz, Ben; Robock, Alan (2020): North Atlantic Oscillation response in GeoMIP experiments G6solar and G6sulfur: why detailed modelling is needed for understanding regional implications of solar radiation management. In Atmospheric Chemistry and Physics. DOI: 10.5194/acp-2020-802. (in review)

"Proposed SRM schemes aim to increase planetary albedo to reflect more sunlight back to space and induce a cooling that acts to partially offset global warming. Under the auspices of the Geoengineering Model Intercomparion Project, we have performed model experiments whereby global temperature under the high forcing SSP5–8.5 scenario is reduced to follow that of the medium forcing SSP2–4.5 scenario."

Rickels, Wilfried; et al. (2020): Who turns the global thermostat and by how much?

Rickels, Wilfried; Quaas, Martin; Ricke, Kate; Quaas, Johannes; Moreno-Cruz, Juan; Smulders, Sjak (2020): Who turns the global thermostat and by how much? In Energy Economics, p. 104852. DOI: 10.1016/j.eneco.2020.104852.

"We set up a quantitative model to analyze efficient levels of SRM deployment against the climatic and economic background conditions projected by the various Shared Socioeconomic Pathways (SSPs) baseline scenarios for the year 2050."

Robrecht, Sabine; et al. (2020): Potential of future stratospheric ozone loss in the mid-latitudes under climate change and sulfate geoengineering

Robrecht, Sabine; Vogel, Bärbel; Tilmes, Simone; Müller, Rolf (2020): Potential of future stratospheric ozone loss in the mid-latitudes under climate change and sulfate geoengineering. In Atmospheric Chemistry and Physics. DOI: 10.5194/acp-2020-747.

"We investigate the likelihood for the occurrence of heterogeneous chlorine activation and its impact on ozone in the lowermost stratospheric mixing layer between tropospheric and stratospheric air above central North America (30.6–49.6° N, 72.25–124.75° W) in summer for conditions today, at the mid and at the end of the 21st century."

Daniel Bodansky; Hugh Hunt (2020): Arctic Climate Interventions

Daniel Bodansky; Hugh Hunt (2020): Arctic Climate Interventions. In The International Journal of Marine and Coastal Law 35 (3), pp. 596–617. DOI: 10.1163/15718085-BJA10035.

"Even if one believes that global climate interventions, such as injecting aerosols into the stratosphere to scatter sunlight, pose unacceptable risks and should be disqualified from consideration, Arctic interventions differ in important respects. They are closer in kind to conventional mitigation and adaptation and should be evaluated in similar terms. It is unclear whether they are feasible and would be effective in saving the Arctic. But given the importance of the Arctic, they should be investigated fully."

Yang, Yi; et al. (2020): Restoring Abandoned Farmland to Mitigate Climate Change on a Full Earth

Yang, Yi; Hobbie, Sarah E.; Hernandez, Rebecca R.; Fargione, Joseph; Grodsky, Steven M.; Tilman, David et al. (2020): Restoring Abandoned Farmland to Mitigate Climate Change on a Full Earth. In One Earth 3 (2), pp. 176–186. DOI: 10.1016/j.oneear.2020.07.019.

"In this perspective, we present an overview of how carbon capture and storage on abandoned farmland can be accelerated and maximized via managing plant diversity as both a means and an end of restoration, creating and applying biochar to soil, and co-developing with renewable energy as techno-ecological synergies."

Pomponi, Francesco; et al. (2020): Buildings as a Global Carbon Sink? A Reality Check on Feasibility Limits

Pomponi, Francesco; Hart, Jim; Arehart, Jay H.; D’Amico, Bernardino (2020): Buildings as a Global Carbon Sink? A Reality Check on Feasibility Limits. In One Earth 3 (2), pp. 157–161. DOI: 10.1016/j.oneear.2020.07.018.

"The built environment is hard to decarbonize but has a pivotal role in climate-change mitigation amid rapid urbanization. Substituting conventional building materials with bio-based materials that store carbon offers one possible solution. Here, we reflect on the capacity of global forests to deliver the floor area required by mid-century."

Schweizer, Vanessa J.; et al. (2020): Integrated Climate-Change Assessment Scenarios and Carbon Dioxide Removal

Schweizer, Vanessa J.; Ebi, Kristie L.; van Vuuren, Detlef P.; Jacoby, Henry D.; Riahi, Keywan; Strefler, Jessica et al. (2020): Integrated Climate-Change Assessment Scenarios and Carbon Dioxide Removal. In One Earth 3 (2), pp. 166–172. DOI: 10.1016/j.oneear.2020.08.001.

" This primer provides an overview of the purposes of scenarios in climate-change research and how they are used. It also introduces the integrated scenario framework and why it came about. CDR studies using the scenario framework, as well as its limitations, are discussed. Possible future developments for the scenario framework are highlighted, especially in relation to CDR."

Fajardy, Mathilde; Mac Dowell, Niall (2020): Recognizing the Value of Collaboration in Delivering Carbon Dioxide Removal

Fajardy, Mathilde; Mac Dowell, Niall (2020): Recognizing the Value of Collaboration in Delivering Carbon Dioxide Removal. In One Earth 3 (2), pp. 214–225. DOI: 10.1016/j.oneear.2020.07.014.

"This study explores the mechanisms behind cost-optimal BECCS deployment with evolving regional CO2 removal targets and energy sectors to provide insights into the ways in which different regional players will interact as a function of their bio-geophysical endowments and their ability to trade these assets. An important finding is that inter-regional cooperation—in choosing the right burden-sharing principle to establish regional targets—and collaboration—in trading negative emissions credits and biomass—are central to sustainably and affordably meeting these targets."

Cox, Emily; et al. (2020): Barriers to Negative-Emissions Technologies

Cox, Emily; Honegger, Matthias; Gadikota, Greeshma; Røttereng, Jo-Kristian Stræte; Schaeffer, Roberto; Colvin, R. M. et al. (2020): Barriers to Negative-Emissions Technologies. In One Earth 3 (2), pp. 137–139. DOI: 10.1016/j.oneear.2020.07.017.

"Modeling suggests that negative emissions will most likely be necessary for keeping climate change this century within the Paris Agreement’s 2°C limits. Beyond technical feasibility, the rapid deployment of negative-emissions technologies (NETs) presents practical, economic, socio-political, and ethical challenges. Which of these presents the greatest barrier to the deployment of Paris-compatible NETs?"
