The United Nations (UN) proclamation of 2021-2030 as a Decade of Ocean Science for Sustainable Development recognizes the interrelationship between climate change and the Earth’s oceans. Reversing the decline of ocean health and taking meaningful action on climate change requires empowering all stakeholders and rightsholders – including youth – to help develop and implement adaptative solutions. Our cluster approaches this issue from an informational justice perspective, emphasizing the right by all to access information and knowledge, have equal opportunity to directly participate in the production and dissemination of information and knowledge, and have their identities and culture be recognized, respected, and fairly represented in the informational world. Guided by this framework, our research addresses the fundamental question: How can we improve knowledge production, exchange, and use among diverse actors to build an understanding of ocean and climate change that enables societal mobilization towards a sustainable future?
