The urgent need for climate change mitigation has resulted in the global adoption of net-zero goals. The proper utilization of the Earth’s oceans, which play an important role in carbon sequestration and storage, is a critical component of these goals. The Global Ocean Science Report 2020 (GOSR 2020) from UNESCO provides valuable insights into the state of ocean science, the potential for ocean-based climate solutions, and the investments required to enable effective climate change mitigation. This article will examine the GOSR 2020 key findings and discuss how they relate to achieving net zero goals. 

The Importance of Ocean-Based Climate Solutions 

The oceans play an important role in regulating global climate and maintaining the delicate balance of our planet’s ecosystems. They act as a massive carbon sink, absorbing roughly 25% of the annual CO2 emissions produced by human activity. Blue carbon sequestration, or the capture and long-term storage of atmospheric CO2 by marine ecosystems, is a critical component of ocean-based climate solutions. 

The GOSR 2020 emphasizes the importance of gaining a better understanding of the ocean’s role in climate change mitigation and adaptation. It emphasizes the significance of interdisciplinary research and collaboration among scientists, policymakers, and stakeholders in developing effective ocean-based strategies to achieve net zero goals. 

The Global Ocean Science Report 2020’s Key Findings 

Inadequate Ocean Science Funding 

According to the GOSR 2020, global investments in ocean science are insufficient, accounting for only 1.7% of total global R&D expenditures. This underinvestment limits our understanding of the oceans’ role in the climate system and our ability to capitalize on their carbon-sequestering potential. 

The Contribution of Coastal and Marine Ecosystems 

Mangroves, seagrass meadows, and saltmarshes, for example, have a remarkable capacity to sequester and store carbon. The GOSR 2020 emphasizes the importance of better monitoring, management, and restoration of these ecosystems in order to fully realize their potential for climate change mitigation. 

Technologies and Practices in Development 

Several emerging technologies and practices can help with blue carbon sequestration and net zero goals. These include marine permaculture, offshore wind energy, and carbon capture and storage in the sea. The GOSR 2020 emphasizes the importance of additional research and development in these areas in order to maximize their potential and reduce their environmental impact. 

The Importance of Capacity Building and International Cooperation 

According to the GOSR 2020, there are significant disparities in ocean science capacity between countries and regions. It advocates for increased capacity building and international collaboration to ensure that all nations can contribute to and benefit from growing ocean knowledge and understanding. 

The Value of Ocean Literacy 

Ocean literacy, or understanding the ocean’s impact on humans and vice versa, is critical for building public support for ocean conservation and climate change mitigation efforts. The GOSR 2020 emphasizes the importance of improved ocean literacy programs and initiatives to raise awareness about the importance of the oceans and their role in achieving net zero goals. 

Recommendations for Reaching Net Zero Goals Using Ocean-Based Climate Solutions 

Based on the GOSR 2020 findings, the following recommendations can assist nations in achieving net zero goals through ocean-based climate solutions: 

Increase Ocean Science Investments 

Ocean science research, innovation, and capacity building should be prioritized by governments and organizations. This will help us better understand the oceans’ role in the climate system and allow us to develop effective ocean-based climate solutions. 

Safeguard and Restore Countries should implement policies and programs to protect and restore critical coastal and marine ecosystems such as mangroves, seagrass meadows, and saltmarshes. This will help them maximize their blue carbon sequestration and storage potential. 

Encourage the Use of Emerging Technologies and Practices 

Governments, businesses, and research institutions should work together to advance the development and deployment of emerging blue carbon sequestration technologies and practices. These efforts should be aimed at reducing the environmental impact of these technologies while also maximizing their potential. 

Encourage international cooperation and capacity building 

Countries should collaborate to share knowledge, resources, and expertise in order to build capacity in ocean science, especially in developing countries. This will help to ensure that all countries can contribute to and benefit from the growing understanding of the oceans and their potential to mitigate climate change. 

Increase Public Awareness and Ocean Literacy 

Priority should be given to initiatives and programs that promote ocean literacy and raise public awareness about the importance of the oceans in climate change mitigation. Engaging the public in ocean conservation efforts is critical for driving the necessary behavioral, policy, and investment changes needed to achieve net zero goals. 

The GOSR 2020 provides important insights into the current state of ocean science and the potential of ocean-based climate solutions for achieving net zero goals. Countries can harness the power of the oceans for effective climate change mitigation by increasing investments in ocean science, protecting and restoring coastal and marine ecosystems, promoting emerging technologies and practices, fostering international collaboration and capacity building, and improving ocean literacy. To achieve a sustainable future, we must recognize the enormous value of our oceans and take the necessary precautions to protect and preserve them.
