The Department of Science and Technology requires a risk assessment on future climate intervention strategies. Produce a report analyzing the catastrophic unintended consequences and irreversible global risks associated with solar radiation management or carbon capture technologies. Provide a personal moral judgment on the 'right' of humanity to intentionally modify planetary systems, and outline three crucial geopolitical questions regarding unilateral deployment of such technologies. The report should be titled: Geoengineering: The Ethical Quagmire of Planetary-Scale Climate Manipulation.
