Lee, Hanna; et al. (2021): The response of terrestrial ecosystem carbon cycling under different aerosol-based radiation management geoengineering

Lee, Hanna; Muri, Helene; Ekici, Altug; Tjiputra, Jerry; Schwinger, Jörg (2021): The response of terrestrial ecosystem carbon cycling under different aerosol-based radiation management geoengineering. In Earth Syst. Dynam. 12 (1), pp. 313–326. DOI: 10.5194/esd-12-313-2021.

"Here we assess the changes in ecosystem carbon exchange and storage among different terrestrial biomes under three aerosol-based radiation management methods with the baseline of RCP8.5 using an Earth system model (NorESM1-ME)."

Visioni, Daniele; et al. (2021): Identifying the sources of uncertainty in climate model simulations of solar radiation modification with the G6sulfur and G6solar Geoengineering Model Intercomparison Project (GeoMIP) simulations

Visioni, Daniele; MacMartin, Douglas G.; Kravitz, Ben; Boucher, Olivier; Jones, Andy; Lurton, Thibaut et al. (2021): Identifying the sources of uncertainty in climate model simulations of solar radiation modification with the G6sulfur and G6solar Geoengineering Model Intercomparison Project (GeoMIP) simulations. Preprint. In Atmos. Chem. Phys. DOI: 10.5194/acp-2021-133.

"We present here results from the Geoengineering Model Intercomparison Project (GeoMIP) simulations for the experiment G6sulfur and G6solar for six Earth System Models participating in the Climate Model Intercomparison Project (CMIP) Phase 6. The aim of the experiments is to reduce the warming from that resulting from a high-tier emission scenario (Shared Socioeconomic Pathways SSP5-8.5) to that resulting from a medium-tier emission scenario (SSP2-4.5)."

Project: Arctic Ice Project

"The most studied ice restoration effort in the world. We’re developing a safe, localized technique to enhance the Arctic’s natural ability to reflect solar radiation out of the atmosphere, increase the Earth’s planetary albedo, and slow the rate of global warming."

Liu, Jiaojiao; Shi, Xiangjun (2021): Estimating the potential cooling effect of cirrus thinning achieved via the seeding approach

Liu, Jiaojiao; Shi, Xiangjun (2021): Estimating the potential cooling effect of cirrus thinning achieved via the seeding approach. Preprint. In Atmos. Chem. Phys. DOI: 10.5194/acp-2021-148.

"A simulation using the Community Atmosphere Model version 5 (CAM5) with the flexible seeding method shows a global cooling effect of 1.36 ± 0.18 W m−2, which is approximately two-thirds of that from artificially turning off homogeneous nucleation (−1.98 ± 0.26 W m−2)."

Cherry, Todd L.; et al. (2021): Does solar geoengineering crowd out climate change mitigation efforts? Evidence from a stated preference referendum on a carbon tax

Cherry, Todd L.; Kallbekken, Steffen; Kroll, Stephan; McEvoy, David M. (2021): Does solar geoengineering crowd out climate change mitigation efforts? Evidence from a stated preference referendum on a carbon tax. In Climatic Change 165 (1-2), pp. 1–8. DOI: 10.1007/s10584-021-03009-z.

"Adding to a limited body of empirical evidence, we use a survey experiment to estimate how informing the U.S. public about solar geoengineering impacts support for a proposed national carbon tax. In contrast to the crowding-out hypothesis, we find that respondents who are provided with information about geoengineering are significantly more likely to support the tax."

The Guardian: 'It is the question of the century': will tech solve the climate crisis – or make it worse?

"Robots on coral reefs, vast barriers to hold back the glaciers, simulated volcanic eruptions to offset global heating ... Can technology repair the mess we have made? Elizabeth Kolbert is not convinced."

Job: Post-doctoral research position on assessing solar radiation management (SRM) and carbon dioxide removal (CDR) technologies

Deadline: 05. April 2021

"The successful candidate will contribute to a comprehensive and systematic assessment of CDR and SRM technologies, focusing on their environmental, technical, social, legal, and political feasibility. Our aim is to provide an urgently needed interdisciplinary perspective on their development and potential use alongside conventional mitigation policies to avoid dangerous climate change."
