Cyclone Activity Linked to Reduced Ocean Carbon Uptake, Study Finds
• A recent study published in *Nature Geoscience* highlights the impact of tropical cyclones on oceanic carbon dynamics.
• Cyclones, known to stir up stored carbon dioxide (CO2) from the ocean, have been linked to a significant reduction in the ocean's ability to act as a carbon sink.
• Between 1993 and 1997, the ocean's carbon outgassing rate was estimated at 16%, but this dropped to 4.5% in the 2010s.
Why It's Important?
The study underscores the dual role of cyclones in influencing global carbon cycles. While they disrupt CO2 absorption, they may also contribute to increased ocean acidification if emissions remain unchecked. This poses risks to marine ecosystems and global climate stability. High-pollution nations, particularly China, are identified as key contributors to rising emissions, which could amplify these effects. The findings call for a reevaluation of global climate policies, especially in addressing emissions from developing nations.
