Left/Southern Ocean/Right/Southern Ocean on map/Image: AI Generated Scientists compared climate benefits and ecological risks across the world's major ocean regions The Southern Ocean delivered the strongest balance between carbon removal and ecosystem protection Some regions experienced high ecological costs despite removing carbon efficiently Southern Ocean: Higher carbon-removal efficiency with lower ecological risk.
Equatorial Pacific and global fertilisation: High carbon-removal efficiency but substantially higher ecological impacts. Subtropical oceans: Lower carbon-removal efficiency accompanied by moderate ecological risks. Much of
the captured carbon eventually returns to the atmosphere Carbon removal alone cannot determine whether ocean fertilisation should be used
