Austin, Maura M.K.; Converse, Benjamin A. (2021): In search of weakened resolve: Does climate-engineering awareness decrease individuals’ commitment to mitigation?

Austin, Maura M.K.; Converse, Benjamin A. (2021): In search of weakened resolve: Does climate-engineering awareness decrease individuals’ commitment to mitigation? In Journal of Environmental Psychology 356 (6335), p. 101690. DOI: 10.1016/j.jenvp.2021.101690.

"As climate predictions become more dire, it is increasingly clear that society cannot rely on mitigation alone. In response, climatologists and engineers have been developing climate-engineering technology to directly intervene on the climate through strategies such as solar radiation management and carbon dioxide removal. While these technologies have some encouraging features, they also involve risk on many dimensions. One behavioral risk that concerns many observers is the possibility that the prominence of climate-engineering scenarios could decrease the public's commitment to mitigation, a concern variously described as moral hazard or weakened resolve. Across 8 experiments (N = 2514) we tested whether exposure to naturalistic information about climate-engineering technology decreases individuals' commitment to mitigation efforts."

Belaia, Mariia; et al. (2021): Optimal Climate Policy in 3D: Mitigation, Carbon Removal, and Solar Geoengineering

Belaia, Mariia; Moreno-Cruz, Juan B.; Keith, David W. (2021): Optimal Climate Policy in 3D: Mitigation, Carbon Removal, and Solar Geoengineering. In Clim. Change Econ., p. 2150008. DOI: 10.1142/S2010007821500081.

"We introduce solar geoengineering (SG) and carbon dioxide removal (CDR) into an integrated assessment model to analyze the trade-offs between mitigation, SG, and CDR."

Osaka, Shannon; et al. (2021): Framing “nature‐based” solutions to climate change

Osaka, Shannon; Bellamy, Rob; Castree, Noel (2021): Framing “nature‐based” solutions to climate change. In Wiley Interdisciplinary Reviews: Climate Change. DOI: 10.1002/wcc.729.

"We review what counts (and what does not count) as a natural solution, and find that those labeled natural are routinely framed under technical and social appraisal criteria as being more beneficial, cost effective, mature, and democratic than ostensibly artificial counterparts."

Princiotta, Frank T. (2021): The Climate Mitigation Challenge-Where Do We Stand?

Princiotta, Frank T. (2021): The Climate Mitigation Challenge-Where Do We Stand? In Journal of the Air & Waste Management Association (1995). DOI: 10.1080/10962247.2021.1948458.

"For the U.S., a unique model examines key impactful mitigation actions and quantifies the monumental challenge of achieving net zero emissions by 2050. Also examined are the different mitigation trajectories needed for developed versus developing countries, how different emission trajectories would affect warming this century, and a summary of the status of R, D& D needs for key technologies."

Beck, S.; Oomen, Jeroen (2021): Imagining the corridor of climate mitigation – What is at stake in IPCC’s politics of anticipation?

Beck, S.; Oomen, Jeroen (2021): Imagining the corridor of climate mitigation – What is at stake in IPCC’s politics of anticipation? In Environmental Science & Policy 123, pp. 169–178. DOI: 10.1016/j.envsci.2021.05.011.

"The article examines how the Intergovernmental Panel on Climate Change (IPCC) performs its self-proclaimed role as ‘mapmaker. We seek to contribute to the emerging literature on global environmental assessments (GEA) and climate politics by reconstructing how the IPCC imagines the corridor for climate mitigation."

Hannah, Lee (2022): Chapter 21 - Mitigation: Reducing Greenhouse Gas Emissions, Sinks, and Solutions

Hannah, Lee (2022): Chapter 21 - Mitigation: Reducing Greenhouse Gas Emissions, Sinks, and Solutions. In Lee Jay Hannah (Ed.): Climate change biology. Third edition. London, [Amsterdam]: Academic Press, pp. 439–472.

"Stopping climate change requires much more than emissions reductions: it requires stabilizing atmospheric greenhouse gas (GHG) concentrations. In the absence of large new additional sinks for CO2 and other GHGs, stabilization equates to reducing emissions nearly to zero. In turn, near-zero emissions means complete transition of the world's energy supply to renewable (non-CO2-emitting) sources. This is a huge task—one that will need to be accomplished in stages."

Grant, Neil; et al. (2021): Confronting mitigation deterrence in low-carbon scenarios

Grant, Neil; Hawkes, Adam; Mittal, Shivika; Gambhir, Ajay (2021): Confronting mitigation deterrence in low-carbon scenarios. In Environ. Res. Lett. DOI: 10.1088/1748-9326/ac0749.

"Here we conduct an in-depth analysis into the relationship between emissions reduction and emissions removal in a global integrated assessment model. We explore the impact of CDR on low-carbon scenarios, illustrating how the pathway for the 2020s is highly sensitive to assumptions around CDR availability."

Honegger, Matthias; Burns, Wil; Morrow, David R. (2021): Is carbon dioxide removal ‘mitigation of climate change’?

Honegger, Matthias; Burns, Wil; Morrow, David R. (2021): Is carbon dioxide removal ‘mitigation of climate change’? In RECIEL. DOI: 10.1111/reel.12401.

"We unpack how the ‘mitigation of climate change’ – as defined in the United Nations Framework Convention on Climate Change and its Paris Agreement – includes CDR as defined by the Intergovernmental Panel on Climate Change."

Keyßer, Lorenz T.; Lenzen, Manfred (2021): 1.5 °C degrowth scenarios suggest the need for new mitigation pathways

Keyßer, Lorenz T.; Lenzen, Manfred (2021): 1.5 °C degrowth scenarios suggest the need for new mitigation pathways. In Nat Comms 12 (1), p. 2676. DOI: 10.1038/s41467-021-22884-9.

"As a first step to address this gap, this paper compares 1.5  °C degrowth scenarios with IPCC archetype scenarios, using a simplified quantitative representation of the fuel-energy-emissions nexus. Here we find that the degrowth scenarios minimize many key risks for feasibility and sustainability compared to technology-driven pathways, such as the reliance on high energy-GDP decoupling, large-scale carbon dioxide removal and large-scale and high-speed renewable energy transformation."

Giannousakis, Anastasis; et al. (2021): How uncertainty in technology costs and carbon dioxide removal availability affect climate mitigation pathways

Giannousakis, Anastasis; Hilaire, Jérôme; Nemet, Gregory F.; Luderer, Gunnar; Pietzcker, Robert C.; Rodrigues, Renato et al. (2021): How uncertainty in technology costs and carbon dioxide removal availability affect climate mitigation pathways. In Energy 216, p. 119253. DOI: 10.1016/j.energy.2020.119253.

"We assess how energy supply costs and carbon dioxide removal (CDR) availability affect mitigation by performing a sensitivity analysis with the energy-economy-climate model REMIND. We use new scenarios with carbon price paths that aim to reduce the frequently seen temperature overshoot."
