As an agency dedicated to ocean conservation and sustainability, we always keep a close eye on the latest scientific findings about our blue planet. The recently released UN State of the Ocean Report 2024 provides critical insights into the current health of our oceans. Here are 12 key takeaways that everyone should know:

1. Plastic Pollution Crisis Deepens

Our oceans are choking on plastic. The report states, "It has been estimated that there are over 170 trillion plastic particles floating in the ocean, based on data from 11,777 stations, weighing between 1.1 and 4.9 million tonnes." This pollution continues to worsen, threatening marine life at every level.

2. Acidification Accelerates 

As our oceans absorb more carbon dioxide, they're becoming increasingly acidic. Scientists predict "ocean acidification by more than 100% by the end of the century," posing existential threats to coral reefs and shellfish. While the open ocean's pH decline is well-documented, coastal areas are experiencing even faster rates of acidification due to additional local stressors such as pollution and agricultural runoff.

3. Warming Waters 

The ocean is heating up faster than ever. "The upper 2,000 m of the ocean continued to warm in 2023 at a rate of 0.32 ± 0.03 W/m² since 1960." This warming trend is disrupting currents, rising sea levels, and damaging fragile ecosystems.

4. Marine Protected Areas: Vital Sanctuaries

"More than 70% of endangered species are reported to seek shelter in Marine Protected Areas." These zones are crucial for biodiversity and sustainable fisheries. Yet the report also highlights that only 2.4% of the ocean is currently designated as "no-take zones" with the highest level of protection.

5. Observation Gaps 

While we've made progress in monitoring our oceans, significant blind spots remain. The Global Ocean Observing System "comprises 8,000 observing platforms, operated by 84 countries through 300 programmes, delivering more than 120,000 observations daily." However, expanding our global observation network, especially in the Southern Hemisphere and polar regions, is crucial.

6. Harmful Algal Blooms on the Rise

As coastal development intensifies and demand for seafood grows, harmful algal blooms are becoming more frequent and severe. "Among the approximately 10,000 species of marine phytoplankton in the world's oceans today, some 200 taxa produce toxins." This poses risks to both marine life and human health.

7. Tsunami Preparedness Improves, But Challenges Remain

Approximately 150 countries and territories are actively contributing to global efforts in tsunami hazard resilience. However, we're still struggling to predict tsunamis from non-seismic sources like underwater volcanoes.

8. Aquaculture Boom

Fisheries and aquaculture production continues to grow, reaching a record of 218 million tonnes in 2021. Farmed seafood is playing an increasingly vital role in global food security.

9. Better Ocean Forecasting

Our ability to predict ocean conditions is improving. "After four decades of investment, global, regional and coastal operational, ocean prediction systems have matured, providing accurate forecasts to diverse users." However, a North-South divide in forecasting capabilities persists.

10. Rising Seas

Sea level rise is accelerating due to melting ice sheets and warming oceans. The report notes that "the global mean sea level displays interannual oscillations that are mostly due to El Niño/La Niña events." This poses an existential threat to coastal communities worldwide.

11. Carbon Removal: Proceed with Caution

Scientists are exploring ways to remove carbon dioxide from the atmosphere using the ocean. The report highlights that "the ocean contains 40 times more carbon compared to the atmosphere." However, we need much more research to understand potential ecosystem impacts before large-scale deployment.

12. Ocean Literacy: Progress and Challenges

Global efforts to improve ocean literacy are expanding. The report notes that "418 activities, 27 projects and the Ocean Literacy with All programme were endorsed by the UN Ocean Decade under Challenge 10 and Outcome 7." However, 72% of leading institutions are still from the Global North. We need more diverse voices and perspectives in ocean education and outreach.

‍

The State of the Ocean Report 2024 paints a complex picture. While we've made progress in some areas, many challenges are intensifying. As an agency, these findings reinforce our commitment to evidence-based ocean conservation and the critical need for international cooperation to protect our blue planet.
