Biodiversity, the variety of life forms on Earth, is crucial for maintaining ecosystem balance and is currently threatened by human-induced climate change. Geoengineering, involving large-scale interventions like Carbon Dioxide Removal (CDR) and Solar Radiation Management (SRM), aims to restore this equilibrium. As global warming risks exceeding 1.5 °C, rapid biodiversity loss and ecosystem disruption become imminent. Geoengineering solutions, though promising, carry significant risks, including potential ozone depletion and unforeseen ecological impacts. Effective governance, involving both state and non-state actors, and robust policy frameworks are essential to ensure these interventions support biodiversity and global climate goals without causing further harm.
