Geoengineering, climate change and ecological security
Matt McDonald
Abstract
Is it possible to imagine the deployment of geoengineering in the service of ecological security? Ecological security––a concern with the resilience of ecosystems––appears to caution against forms of intervention that might serve to change and/or undermine the functionality of ecosystems. Yet ecosystem functionality is already challenged by processes associated with climate change, and some degree of climate change is already locked in. This paper examines this challenging but important issue. After defining ecological security and noting varied forms of geoengineering, the paper explores the opportunities for––and challenges of––imagining geoengineering in the service of ecological security, especially in the context of solar radiation management. While arguing that it is possible to conceive a role for geoengineering in the service of ecological security, this must be contingent on extensive research supporting deployment and must be tempered by restraint and a commitment to precaution, humility, reflexivity and dialogue.
