Read the following passage carefully:
The deployment of solar radiation management (SRM) geoengineering is increasingly framed by policy technocrats as an indispensable stopgap against catastrophic planetary tipping points. However, translating technical feasibility into equitable international climate governance reveals profound structural paradoxes. Proponents argue that SRM offers a low-cost mechanism to temporarily offset thermal forcing while global decarbonization efforts mature. Yet, this narrow efficiency focus obscures severe systemic vulnerabilities, primarily the risk of moral hazard, wherein reliance on an engineered fix weakens political determination to enforce deep structural emissions reductions. Furthermore, SRM governance faces an intractable geopolitical asymmetry: unilateral deployment by a single technologically advanced nation or sub-national coalition could drastically alter transboundary precipitation regimes and agricultural productivity in neighboring regions without prior informed consent. Existing multilateral environmental treaties, historically calibrated for domestic emissions monitoring and compensatory frameworks, lack both statutory authority and binding enforcement tools to manage such unilateral planetary interventions. Consequently, institutionalizing SRM as a core pillar of climate policy threatens to entrench a perilous dependency on high-stakes ecological intervention while failing to confront the root socio-economic drivers of global ecological crisis.
Which of the following best reflects the central thesis of the passage?
- ASolar radiation management is fundamentally ineffective because aerosol injection cannot physically alter atmospheric carbon dioxide concentrations or prevent ocean acidification.
- Elevating solar radiation management to a core climate strategy is problematic because it risks weakening decarbonization resolves while generating unmanageable transboundary governance dilemmas.Cevap
- CMultilateral environmental treaties have successfully regulated solar radiation management by establishing binding compensatory frameworks for affected neighboring nations.
- DTechnological geoengineering must be completely prohibited internationally to prevent rogue nations from weaponizing solar radiation management against developing agrarian economies.
