An ocean narrative is a powerful tool for making complex ocean changes better accessible while informing decision-making and inspiring collective action. This ocean narrative reports on ocean change in the northeastern Atlantic and adjacent seas and discusses its broader implications for Europe’s environment, economy, and society. The region is experiencing warming and acidification at rates exceeding the global average, with rising sea levels and record severe marine heatwaves (MHWs). These changes threaten marine ecosystems, biodiversity, cultural heritage, and key economic sectors, such as aquaculture and coastal tourism, which rely heavily on the balance and the health of the ocean. This ocean narrative emphasizes the importance of regional ocean indicators for the northeastern Atlantic and adjacent seas and underscores the importance of localized responses, as ocean changes affect regions differently, particularly in semi-enclosed seas such as the Baltic Sea, the Black Sea, and the Mediterranean Sea. The findings stress the urgency of timely action and the need to strengthen evidence-based and strategic ocean knowledge transfer at the science and policy interface for informed decision-making that balances environmental sustainability, economic resilience, and social inclusivity to address the growing challenges of ocean change in the northeastern Atlantic and its adjacent seas.
