Carbon dioxide removal methods could worsen marine oxygen loss, study warns

Methods to enhance the ocean's uptake of carbon dioxide (CO₂) are being explored to help tackle the climate crisis. However, some of these approaches could significantly exacerbate ocean deoxygenation. Their potential impact on marine oxygen must therefore be systematically considered when assessing their suitability.
