A groundbreaking global study published in Nature Climate Change has placed a trillion-dollar value on the ocean’s role in removing carbon from the atmosphere, spotlighting tropical marine regions like the Philippines as critical players in climate mitigation. The study, released March 27, estimates that the ocean’s biological carbon pump (BCP) sequesters approximately 2.81 billion metric tons (Gt) of carbon annually—roughly 10 billion tons of carbon dioxide (CO₂)—locking it away for at least 50 years.
