Executive Summary
A UNESCO report warns that major gaps in ocean carbon data could skew climate models and weaken mitigation and adaptation planning
- UNESCO IOC says ocean carbon uptake remains poorly understood
- The ocean stores about 25 percent of global CO2 emissions
- Model estimates differ by 10 to 20 percent globally and more in some regions
- The report cites limited long-term data and missing process knowledge
- Coastal, polar, and deep ocean regions are still under-measured
- It calls for a global observing system with satellites, autonomous platforms, and sustained measurements
- Improved modeling and international cooperation are needed to guide climate policy
Quick Facts
- What: Released a report on ocean carbon knowledge gaps
- Where: Global ocean with focus on coastal and polar regions
- Why: To improve climate projections and policy planning
- Who: UNESCO IOC and 72 authors from 23 countries
- When: Published at Ocean Sciences Meeting 2026
