State of ocean 2024: Wake up call for the world

The latest UNESCO “State of the Ocean Report 2024” has landed, and it paints a stark picture of the challenges facing our blue planet. While we’re gathering more data than ever before, the truth is, the ocean’s health is declining faster than we can fully understand or fix it. This report, framed by the UN Decade of Ocean Science for Sustainable Development, underscores the urgent need for more intense scientific efforts and for us to better translate that knowledge into real-world action.

Key takeaways from the report

Our understanding of the ocean is still surprisingly limited, which makes tackling the growing environmental crises even tougher. We need more research to grasp the complex changes happening beneath the surface.

• Pollution from excess nutrients (like nitrogen and phosphorus, mainly from our activities on land like farming and wastewater) continues to choke our oceans. We need stronger rules, better enforcement, and innovative solutions to curb these inputs.
• The amount of plastic in the ocean has skyrocketed since the 90s and is set to get much worse. We urgently need global solutions to track and stop plastic pollution at every stage of its lifecycle.
• Ocean acidification, driven by the massive amounts of CO2 our ocean absorbs, is a major and growing threat. We need to understand the local impacts better to develop effective strategies.
• The ocean is warming at an alarming rate, from the surface to the deepest parts. This is fueling sea-level rise, messing with ocean currents, and causing big problems for marine life everywhere.
• Oxygen levels in the ocean are dropping, leading to more “dead zones” where life can’t survive. We need more research to understand the speed and consequences of this deoxygenation.
• Marine Protected Areas (MPA) are vital for endangered species and ocean health, but their effectiveness varies greatly. We need to figure out how to make them truly work to safeguard marine life.
• Coastal ecosystems like mangroves and seagrasses, which are crucial for storing carbon, are disappearing at an alarming rate. We must protect what’s left.
• Marine Spatial Planning (MSP) is being used more and more to manage human activities in the ocean, which is a positive step. But its success depends on good science and adaptable strategies.
• Aquatic foods are a huge source of nutrition globally, and we need to ensure we’re managing our fisheries and aquaculture sustainably to protect ocean ecosystems.
• While we’re getting better at predicting ocean conditions, there’s a big gap in forecasting abilities between the Northern and Southern Hemispheres. We need to bridge this gap so everyone can prepare for ocean-related hazards.
• Sea levels are rising and will continue to accelerate due to melting ice and warmer waters.
• Various technologies are being explored to remove carbon dioxide from the ocean, but we need to be very careful about their potential long-term effects on marine life.
• Harmful Algal Blooms are on the rise, often linked to seafood demand and coastal development. We need more data to understand their causes and develop effective warning systems.
• The Global Ocean Observing System (GOOS) is a massive international effort, but we still have gaps in our observations. We need to invest more in technology and collaboration to get a complete picture of our ocean.
• Efforts to share ocean data are improving, but we need to keep expanding these networks to ensure everyone has access to this vital information.
• Mapping the entire ocean floor is still a major task, with most of it unmapped. We need to keep pushing forward with this effort to better understand our underwater world.
• Finally, engaging everyone – from the public to businesses and especially Indigenous communities – is crucial for inspiring action and achieving a healthy, sustainable ocean.

Conclusion

The State of the Ocean Report 2024 provides a stark reminder of the significant and accelerating challenges confronting the global ocean, emphasizing the urgent need for transformative action.

The interconnected nature of these challenges underscores the necessity of a holistic and globally coordinated response, grounded in robust scientific knowledge, effective policies, and the active engagement of all stakeholders.

Addressing the escalating threats to ocean health is not merely an environmental imperative but a fundamental prerequisite for achieving global sustainability and ensuring the long-term well-being of both present and future generations
