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."

NCAR: CCIS 2020 Webinar Series: Recordings

"Main Goals of the CCIS Webinar Series: Conceptualization of a research framework for assessing proposed climate intervention strategies: Establish shared understanding of ongoing research of climate intervention strategies in different research communities and main challenges. Reach a perspectival integration for completeness of knowledge/understanding. Identify elements of a research program, identify existing and new working groups of such a program."

Parson, Edward A.; Buck, Holly J. (2020): Large-Scale Carbon Dioxide Removal: The Problem of Phasedown

Parson, Edward A.; Buck, Holly J. (2020): Large-Scale Carbon Dioxide Removal: The Problem of Phasedown. In Global Environmental Politics 20 (3), pp. 70–92. DOI: 10.1162/glep_a_00575.

"The future phasedown need implies suggestive guidance for near-term decisions about removal methods and design of associated policy and business environments. First, variation among methods’ scale constraints and cost structures suggests a rough ordering of methods by severity of future phasedown challenges. Second, of the three potential means to motivate removals—profitable products incorporating removed carbon, extended emissions-pricing policies, or public procurement contracts—public procurement appears to present the fewest roadblocks to future phasedown."

Phys.org: Making sense of climate scenarios: Toolkit for decision-makers launched

"To make climate scenarios work for decision-makers, an international team of researchers developed a comprehensive interactive online platform. It is the first of its kind to provide the tools to use those scenarios—from climate impacts to mitigation and energy options—to a broader public beyond science. The scenarios help policy makers and businesses, finance actors and civil society alike to assess the threat of global warming and ways to limit it."

Böttcher, Miranda; et al. (2015): Scenarios on Stratospheric Albedo Modification Deployment in 2030. Workshop Report

Böttcher, Miranda; Gabriel, Johannes; Harnisch, Sebastian (2015): Scenarios on Stratospheric Albedo Modification Deployment in 2030. Workshop Report. Priority Programme 1689 of the German Research Foundation DFG.

"The goal of this SPP 1689 scenario project was to develop a first appraisal of what effects a high-risk climate intervention technology such as SAM could have on the dynamics of international relations. More concretely, it aimed to develop scenarios regarding “Political decision-making on stratospheric albedo modification deployment in 2030” to examine under which conditions states could opt for SAM deployment."
