flag Ocean climate tech may harm marine life; research urges caution.

flag A new study warns that ocean-based climate interventions, including carbon dioxide removal and solar radiation modification, could significantly impact marine ecosystems. flag Methods like iron fertilization, seaweed cultivation, and ocean alkalinity enhancement aim to boost the ocean’s carbon absorption but may disrupt food webs, cause oxygen depletion, or alter chemistry. flag Anoxic storage of biomass and solar radiation modification offer potential cooling but carry risks like altered weather patterns and acidification. flag The research emphasizes that all approaches have ecological trade-offs and require extensive study before any large-scale use.
