Risk-risk analysis
The deployment of sunlight reflection methods (SRM) would come with risks. More comprehensive forms of risk-risk analysis can provide a broader perspective on the policy options available. A look at three levels of analysing SRM risks:
“SRM is risky.”
Considering only the risks of SRM would provide only a narrow assessment.
SRM
“How do SRM risks compare to climate change?”
A simple risk-risk analysis would compare the risks of SRM against the risks of climate change without SRM, all else equal.
vs.
CLIMATE CHANGE WITH SRM
CLIMATE CHANGE WITHOUT SRM
“What about other options and impacts?”
Assessing SRM as part of a broader portfolio of climate policy options would be more thorough.
SRM
Governance challenges
Carbon dioxide removal
Distributional impacts
Mitigation
Adaptation
Dynamic interactions
Uncertainty
Indirect effects
Public behavior
A comprehensive risk-risk analysis would go further, considering broader implications and complexities.
