Manley, Kyle; et al. (2020): Modeling the Dynamic Landscape Evolution of a Volcanic Coastal Environment Under Future Climate Trajectories

Manley, Kyle; Salles, T.; Müller, R. D. (2020): Modeling the Dynamic Landscape Evolution of a Volcanic Coastal Environment Under Future Climate Trajectories. In Front. Earth Sci. 8, p. 437. DOI: 10.3389/feart.2020.550312.

"Olivine weathering is a natural process that sequesters carbon out of the atmosphere, but is now being proposed as a strategy that can be artificially implemented to assist in the mitigation of anthropogenic carbon emissions. We use the landscape evolution model Badlands to identify a region (Tweed Caldera catchment in Eastern Australia) that has the potential for naturally enhanced supply of mafic sediments, known to be a carbon sink, into coastal environments."

Pye, S.; et al. (2020): Modelling net-zero emissions energy systems requires a change in approach

Pye, S.; Broad, O.; Bataille, C.; Brockway, P.; Daly, H. E.; Freeman, R. et al. (2020): Modelling net-zero emissions energy systems requires a change in approach. In Climate Policy, pp. 1–10. DOI: 10.1080/14693062.2020.1824891.

"Energy modelling can assist national decision makers in determining strategies that achieve net-zero greenhouse gas (GHG) emissions. However, three key challenges for the modelling community are emerging under this radical climate target that needs to be recognized and addressed."

Call for Submissions: Special Issue "Resolving uncertainties in solar geoengineering through multi-model and large-ensemble simulations" (ACP/ESD inter-journal SI)

Deadline: 31. July 2022

"To capture the interrelated research amongst these projects, the special issue is set up jointly between Atmospheric Chemistry and Physicsand Earth System Dynamics. In ACP, we invite papers that emphasize process-level understanding and stratospheric dynamics; in ESD, submissions on Earth system effects, feedbacks, and impacts (like agriculture or ecosystem responses) are invited."

Kravitz, Ben; et al. (2020): Comparing different generations of idealized solar geoengineering simulations in the Geoengineering Model Intercomparison Project (GeoMIP)

Kravitz, Ben; MacMartin, Douglas G.; Visioni, Daniele; Boucher, Olivier; Cole, Jason N. S.; Haywood, Jim et al. (2020): Comparing different generations of idealized solar geoengineering simulations in the Geoengineering Model Intercomparison Project (GeoMIP). In Atmospheric Chemistry and Physics (under review). DOI: 10.5194/acp-2020-732.

"Two generations of models in the Geoengineering Model Intercomparison Project (GeoMIP) have now simulated offsetting a quadrupling of the CO2 concentration with solar reduction. This simulation is artificial and designed to elicit large responses in the models. Here we show that energetics, temperature, and hydrological cycle changes in this experiment are statistically indistinguishable between the two ensembles."

Call for Abstracts: Invitation to Submit to AGU 2020 Session on Approaches in Measurements and Modeling for Geoengineering

Deadline: 29. July 2020

"This session solicits contributions from participants who have interest and expertise in measurements and modeling of the Earth System that can be applied to Carbon Dioxide Removal and Solar Radiation Management. Through linking these fields in this session, current technologies and ideas will be shared in both realms, promoting further scientific understanding of geoengineering implications."

Gertler, Charles G.; et al. 2020: “Weakening of the Extratropical Storm Tracks in Solar Geoengineering Scenarios.”

Gertler, Charles G., Paul A. O’Gorman, Ben Kravitz, John C. Moore, Steven J. Phipps, and Shingo Watanabe. 2020: “Weakening of the Extratropical Storm Tracks in Solar Geoengineering Scenarios.” Geophysical Research Letters. https://doi.org/10.1029/2020gl087348.

‌"Here, we first analyze climate model simulations from experiment G1 of the Geoengineering Model Intercomparison Project (GeoMIP), in which a reduction in incoming solar radiation balances a quadrupling of CO2. The Northern Hemisphere extratropical storm track weakens by a comparable amount in G1 as it does for increased CO2 only. The Southern Hemisphere storm track also weakens in G1, in contrast to a strengthening and poleward shift for increased CO2."
