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."

Drake, Henri F.; et al. (2020): A Multi-control Climate Policy Process for a Designated Decision Maker

Drake, Henri F.; Rivest, Ronald L.; Edelman, Alan; Deutch, John (2020): A Multi-control Climate Policy Process for a Designated Decision Maker. Massachusetts Institute of Technology. Cambridge, MA (MIT CEEPR Working Paper Series).

"We present an idealized model of optimally-controlled climate change, which is complementary to simpler analytical models and more comprehensive Integrated Assessment Models. We show that the four methods of controlling climate damage– mitigation, carbon dioxide removal, adaptation, and solar radiation modification– are not interchangeable, as they enter at different stages of the causal chain that connects GHG emissions to climate damages."

Thoni, Terese; et al. (2020): Deployment of Negative Emissions Technologies at the National Level: A Need for Holistic Feasibility Assessments

Thoni, Terese; Beck, Silke; Borchers, Malgorzata; Förster, Johannes; Görl, Knut; Hahn, Alena et al. (2020): Deployment of Negative Emissions Technologies at the National Level: A Need for Holistic Feasibility Assessments. In Front. Clim. 2. DOI: 10.3389/fclim.2020.590305.

"We examine 17 Long-Term Low Greenhouse Gas Emission Development Strategies (LT-LEDS), and discuss them in the context of available NETs feasibility assessments. Our mapping shows that most countries include NETs in their long-term strategies, and that enhancement of natural sinks is the most dominating type of NET in these strategies."

Johansson, Daniel J.A.; et al. (2020): The role of negative carbon emissions in reaching the Paris climate targets: The impact of target formulation in integrated assessment models

Johansson, Daniel J.A.; Azar, Christian; Lehtveer, Mariliis; Peters, Glen P. (2020): The role of negative carbon emissions in reaching the Paris climate targets: The impact of target formulation in integrated assessment models. In Environ. Res. Lett. DOI: 10.1088/1748-9326/abc3f0.

"Across two Integrated Assessment Models (IAMs), we found that the amount of net-negative emissions – when global net emissions fall below zero – depends to a large extent on how the target is represented, i.e. implemented in the model."

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."

Fuhrman, Jay; et al. 2019: “From Zero to Hero?: Why Integrated Assessment Modeling of Negative Emissions Technologies Is Hard and How We Can Do Better.”

Fuhrman, Jay, Haewon McJeon, Scott C. Doney, William Shobe, and Andres F. Clarens. 2019: “From Zero to Hero?: Why Integrated Assessment Modeling of Negative Emissions Technologies Is Hard and How We Can Do Better.” Frontiers in Climate 1 (December). https://doi.org/10.3389/fclim.2019.00011.

"Climate change mitigation strategies informed by Integrated Assessment Models (IAMs) increasingly rely on major deployments of negative emissions technologies (NETs) to achieve global climate targets. Although NETs can strongly complement emissions mitigation efforts, this dependence on the presumed future ability to deploy NETs at scale raises questions about the structural elements of IAMs that are influencing our understanding of mitigation efforts."

Butnar, I., et al. (2019): A Deep Dive into the Modelling Assumptions for Biomass with Carbon Capture and Storage (BECCS): A Transparency Exercise

‌"Through a structured review, we find that all IAMs communicate wider system assumptions and major cost assumptions transparently. This quality however fades as we dig deeper into modelling details."

Baird, J. (2019): The integrated thermodynamic geoengineering/negative emissions OTEC model

Baird, Jim (2019): The integrated thermodynamic geoengineering/negative emissions OTEC model. Energy Central. Available online at https://www.energycentral.com/c/ec/integrated-thermodynamic-geoengineeringnegative-emissions-otec-model.

"The solution advanced in this paper is an amalgam of energy production through the conversion of the heat of global warming to productive energy, (thermodynamic geoengineering (TG)), solar radiation management (SRM) through load balancing trapped solar energy and carbon-dioxide removal (CDR) thru negative-CO2-emissions ocean thermal energy conversion (NEOTEC)."
