International Security Politics and Climate Engineering (ISPACE)
‘Climate engineering’ is rising up the global agenda. Assessments based on technical rationales tend to overlook implications of the international context. In this project, with Olaf Corry (formerly of Copenhagen University, now at Leeds) I am exploring the security dynamics engendered by climate engineering, aiming to contribute to more realistic assessment of the political feasibility and desirability of such methods.
The leading solar geoengineering proposal – ‘stratospheric aerosol injection’ (SAI) – would involve spraying reflective particulates into the stratosphere to ‘dim the sun’ and thereby reduce temperatures. Interest in SAI has increased in some quarters, partly as a response to rapid changes in polar ecosystems with potentially catastrophic impacts, and spreading declarations of a ‘climate emergency’. Experience from volcanic eruptions suggests that particles in the stratosphere may constitute a relatively fast-working and powerful policy lever, but SAI’s side-effects, on rainfall patterns for example, also imply considerable conflict-generation potential.
Little is currently clear about the security political dimensions of SAI. A landmark report noted ‘serious and complex governance issues which need to be resolved if geoengineering is ever to become an acceptable method for moderating climate change’ . Even keen proponents of SAI research warn that it ‘may prove as disruptive to the political order of the 21st century as nuclear weapons were for the 20th’. Potential concerns include: if SAI is deployed will there be conflict over who might do it and to what ends? What role would military interests play in planetary temperature modification infrastructure? Would the prospect of intentional intervention in the climate in itself exacerbate international tensions? And might proposals for SAI undermine international collaboration on climate change mitigation?
In this project we are deliberating with stakeholders from security, diplomatic, scientific and activist communities to explore the different conceptions and imaginaries of climate engineering that might inform and structure emerging political engagements with climate engineering research and development. We've already seen some dramatically contrasting imaginaries ...
