Possible Implications of Climate Engineering for Peace and Security

Abstract

What: An international group of scientists reviewed the potential consequences of climate engineering and provided a first mapping of the problem landscape, identifying knowledge gaps and emerging research questions.

Evaluating climate geoengineering proposals in the context of the Paris Agreement temperature goals

“…At present it is unclear whether any climate geoengineering technology could be implemented in a way that accounts for distributive, intergenerational, corrective, ecological, procedural and other forms of justice 165 . Furthermore, it has been argued that development and eventual deployment of climate geoengineering techniques, especially RFG, may place strains on human security and international relations 166 , resulting in conflict risks and societal instability 167 , 168 . A geoengineered climate would be the result of an intentional intervention attributable to identifiable actors, as opposed to the more ambiguous distribution of responsibility for damages from climate change induced by emissions of CO 2 and other climate forcers.…”

“…Allerdings verbraucht die Gewinnung biogener Treibstoffe in global relevanten Mengen viel Anbaufläche und konkurriert mit der Lebensmittelerzeugung. Das Ausmaß der Anwendbarkeit dieses Verfahrens ist derzeit schwer abschätzbar (Link et al, 2013;IPCC, 2013), weshalb die RCPs in diesem Punkt eine besonders große Spannweite aufweisen (RCP3PD: 85 % Anteil von CCS an der fossilen Energieaufbringung, praktisch kein CCS in RCP8.5, siehe Abbildung 1.11).…”

“…B. Link et al, 2013), mit der das Klimasystem verändert werden könnte. SRM beinhaltet unter anderem das Einbringen von Aerosolen (insbesondere Schwefelsäureaerosol) in die Stratosphäre, wodurch Sonnenstrahlung vermehrt zurück gestreut wird.…”

Climate Change, Security Risks, and Violent Conflicts

“…With respect to climate-related policies and their discursive foundations, two aspects have received particular attention. One is geo-engineering (Brzoska, Link, Maas, and Scheffran 2012;Link, Brzoska, Maas, Neuneck, and Scheffran 2013;Maas and Scheffran 2012), the other migration policy (Baldwin, Methmann, and Rothe 2014;Nash 2018). Overall, researchers from the group have attempted to link empirical research with a critical theoretical perspective, working with concepts such as complexity, tipping points, cascades, and risk multipliers (Scheffran 2016), resilience (Boas and Rothe 2016;Schilling et al 2017;Balbo et al 2016), and the Anthropocene and sustainability transitions (Brauch, Oswald Spring, Grin, and Scheffran 2016).…”
