Podcast: Refreezing the arctic and other climate actions backed by scientific research ft. Dr Shaun Fitzgerald, Centre for Climate Repair at Cambridge

„All your questions on this and more answered on this episode where we discuss Climate action backed by scientific research and robust evidence with Dr Shaun Fitzgerald OBE from Centre for Climate Repair at Cambridge (CCRC) who joins Girish Shivakumar for a conversation. CCRC is also affiliated to the Cambridge Zero initiative.“

Moore, John C.; et al. (2020): Targeted Geoengineering: Local Interventions with Global Implications

Moore, John C.; Mettiäinen, Ilona; Wolovick, Michael; Zhao, Liyun; Gladstone, Rupert; Chen, Ying et al. (2020): Targeted Geoengineering: Local Interventions with Global Implications. In Glob Policy. DOI: 10.1111/1758-5899.12867.

„Targeted geoengineering aims to tackle a global scale impact of climate warming by addressing local or regional systemic interventions. We consider three examples: conserving the West Antarctic ice sheet by limiting rates of ice discharge or increasing snow accumulation, thereby reducing global sea level rise; transforming the Arctic permafrost zone into steppe grassland; raising the albedo of Arctic sea ice.“

„Even if one believes that global climate interventions, such as injecting aerosols into the stratosphere to scatter sunlight, pose unacceptable risks and should be disqualified from consideration, Arctic interventions differ in important respects. They are closer in kind to conventional mitigation and adaptation and should be evaluated in similar terms. It is unclear whether they are feasible and would be effective in saving the Arctic. But given the importance of the Arctic, they should be investigated fully.“

Chen, Yating; et al. 2020: “Mitigation of Arctic Permafrost Carbon Loss through Stratospheric Aerosol Geoengineering.”

Chen, Yating, Aobo Liu, and John C. Moore. 2020: “Mitigation of Arctic Permafrost Carbon Loss through Stratospheric Aerosol Geoengineering.”[nbsp]Nature Communications[nbsp]11 (1). https://doi.org/10.1038/s41467-020-16357-8.

‌“Increasing Earth’s albedo by the injection of sulfate aerosols into the stratosphere has been proposed as a way of offsetting some of the adverse effects of climate change. We examine this hypothesis in respect of permafrost carbon-climate feedbacks using the PInc-PanTher process model driven by seven earth system models running the Geoengineering Model Intercomparison Project (GeoMIP) G4 stratospheric aerosol injection scheme to reduce radiative forcing under the Representative Concentration Pathway (RCP) 4.5 scenario.“

Chen, Y.; et al. (2019): Economic losses of carbon emissions from circum-Arctic permafrost regions under RCP-SSP scenarios

Chen, Y.; Liu, A.; Zhang, Z.; Hope, C.; Crabbe, J. (2019): Economic losses of carbon emissions from circum-Arctic permafrost regions under RCP-SSP scenarios. In: Science of the Total Environment 658, S. 1064–1068. DOI: 10.1016/j.scitotenv.2018.12.299.

„In this study, we use the PInc-PanTher model to estimate carbon emissions from thawing permafrost in the circum-Arctic during 2010–2100 followed by the PAGE09 integrated assessment model to evaluate the net economic losses caused by these permafrost carbon emissions.“

Macias-Fauria, Marc; Jepson, Paul; Zimov, Nikita; Malhi, Yadvinder (2020): Pleistocene Arctic megafaunal ecological engineering as a natural climate solution? In Philosophical transactions of the Royal Society of London. Series B, Biological sciences 375 (1794), p. 20190122. DOI: 10.1098/rstb.2019.0122.

„Here we review the environmental context of megafaunal ecological engineering in the Arctic; explore the mechanisms through which it can help mitigate climate change; and estimate its potential—based on bison and horse, with the aim of evaluating the feasibility of generating an ecosystem shift that is economically viable in terms of carbon benefits and of sufficient scale to play a significant role in global climate change mitigation.“
