Core Viewpoint - The article discusses the launch of the "Marine Solutions Toolkit for Sustainable Coastal City Development," aimed at addressing climate change impacts on coastal cities and promoting sustainable development through scientific collaboration and innovation [1][2][3] Group 1: Toolkit Development and Features - The toolkit consists of six core modules and 24 sub-modules, covering critical areas such as marine and climate warning, marine navigation safety, nearshore ecological health, integrated coastal management, blue economy support, and marine literacy [3] - It integrates marine big data, advanced numerical models, and artificial intelligence technologies to provide visualized products and services for end-users and decision-makers in coastal cities [3] Group 2: Global Collaboration and Participation - The toolkit was developed through collaboration among multiple countries and research institutions, emphasizing a shared design, development, and benefit approach, and is made available to global users for free [2] - Chinese research teams have been deeply involved in the "Ocean Decade" initiative, contributing to strategic planning and platform construction, and leading international scientific programs to enhance global marine governance capabilities [2][3] Group 3: Implications for Sustainable Development - The launch of the toolkit reflects China's commitment to global marine governance and the construction of a marine community with a shared future, aiming to provide technological support for the 21st Century Maritime Silk Road and the establishment of a strong marine nation [3] - The toolkit is expected to facilitate the rapid transfer of scientific knowledge to the public and decision-makers, offering cost-effective solutions for various marine management activities [2]

Core Viewpoint - The "Ocean Decade" initiative, launched by the United Nations, aims to promote sustainable development through marine science cooperation and policy coordination, with significant global participation and various national approaches to implementation [3][4]. Group 1: Implementation Progress - Since the launch of the "Ocean Decade" in 2021, nearly 60 global programs have been initiated, involving approximately 20,000 participants worldwide [4]. - Over 10 countries have established "Ocean Decade" committees, with this number expected to grow, indicating strong momentum in the initiative's first five years [4]. Group 2: Similarities and Differences in Approaches - The implementation paths of the "Ocean Decade" in Western and Eastern countries show more similarities than differences, with a shared commitment to common principles despite varying levels of marine science research [6]. - China has established a high-level "Ocean Decade" committee, enhancing visibility and importance, while other countries like Canada focus on marine literacy and community education [6]. Group 3: Role of Coastal Cities - The "Coastal Cities" platform, initiated by the UN in 2024, aims to connect scientists and NGOs with cities to facilitate better decision-making regarding marine issues [7]. - Qingdao, as a founding city of this platform, serves as a pilot for other cities, emphasizing the importance of urban decision-making in marine governance [7]. Group 4: China's Contributions - China has led multiple initiatives within the "Ocean Decade," including the establishment of the UN "Ocean Decade" Marine and Climate Cooperation Center in Qingdao [10]. - The country has shared marine scientific knowledge and demonstrated innovative work in areas like deep-sea ecosystems and marine carbon sinks, setting an example for global cooperation [10].
