Humanity’s impact on the Earth, especially the climate and the ocean, constitutes an existential threat of unprecedented magnitude. The consequences are dire, including the loss of life and ecosystems, parts of the Earth being rendered uninhabitable, species extinction, and increased vulnerability to disasters.

Effective education and communication are crucial components of climate and ocean change mitigation and adaptation. By imparting knowledge, reinforcing skills, and fostering awareness, education and communication have the power to enable individuals to understand the complexities of the climate and ocean crisis and its existential implications. Education and communication cultivate a sense of responsibility, motivating individuals to adopt sustainable practices and make informed decisions. Education and communication are closely connected and mutually reinforcing: most forms of education depend on communication, and communication is often educational.

Education needs to equip present and future generations with the skills needed to innovate, develop social justice, and advocate for policy changes. Communication fosters critical thinking, enabling us to challenge harmful practices and embrace environmentally conscious alternatives. Thus, education and communication have a heavy responsibility with respect to creating a knowledgeable and engaged citizenry and laying the foundation for collective action and a sustainable future.

We solicit contributions (e.g. original research articles and review articles) from researchers, practitioners, educators, students, policymakers, communicators, activists, and artists working across different sectors (e.g. academia, industry, and nongovernmental organizations). This will be a unique opportunity to explore and enhance climate and ocean communication and education.

With respect to the scope of this special issue, we welcome research articles that investigate a wide variety of topics, including, but not limited to, the following:

• best practices in and innovative approaches to climate and ocean education and communication;
• the ethics and geoethics of climate and ocean education and communication, including social justice and equity;
• the role of technology (including artificial intelligence) and new media in climate and ocean education and communication;
• the intersection of climate and ocean education and communication with other issues, such as biodiversity, sustainable development, and the Sustainable Development Goals (SDGs);
• the impact of climate and ocean education and communication on public opinion, policy, and behaviour;
• the integration of climate and ocean literacy into formal and informal education;
• the role of geoscience research in advancing climate and ocean education and communication;
• scientific investigation of outreach initiatives targeting different age groups, settings, and approaches;
• learners’ content and procedural knowledge of climate science and options for action (e.g. climate feedbacks, impacts, adaptation measures, and renewable energy), cultivating science and communication skills (e.g. quantitative literacy, critical thinking, and writing to inform), initiating positive attitudes and actions (e.g. empathy and behavioural change), and issues related to the transfer of education into action and to timescales needed for mindset and behavioural change.

This special issue aims to (1) provide a high-quality collection of papers showcasing methodological advances in compound- and multi-risk analysis and management, (2) consolidate and foster learning across the compound-risk and (multi-hazard) multi-risk research fields, and (3) identify future research avenues.

Recent years have demonstrated the immense challenges faced by society as a result of the increasing complexity of disaster risk and due to climate change. Societies impacted by multiple natural hazards (either in sequence or at the same time) face different challenges than when impacted by a single hazard that occurs in isolation (AghaKouchak et al., 2020; Hillier and Dixon, 2020; Raymond et al., 2020a). The impacts of compound- and multi-hazard disasters are complex and may be driven by the consecutive nature of the (drivers of) hazards themselves (Hillier et al., 2020; Mora et al., 2018; Ridder et al., 2020; Zscheischler et al., 2018), the spatiotemporal dynamics in exposure and vulnerability caused by earlier events (de Ruiter et al., 2020; de Ruiter and Van Loon, 2022; Reichstein et al., 2021), or the influences of risk management on the dynamics of risk (Simpson et al., 2022). This makes managing compound- and multi-risk disasters especially complex, and several studies have noted that their management may require more comprehensive approaches than single-hazard disasters (Simpson et al., 2023; De Ruiter et al., 2021; Schippers, 2020).

In recent years, international agreements such as the Paris Agreement (2015) and the UN’s Sendai Framework for Disaster Risk Reduction (SFDRR) (UNDRR, 2015) have called upon the disaster risk science community to move away from siloed hazard thinking (i.e. assessing the risk from hazards one by one) and toward improving our understanding of these spatiotemporal complexities of disaster risk. Similarly, the latest series of Intergovernmental Panel on Climate Change (IPCC) reports recognizes the importance of accounting for multiple and complex risks. In a recent survey of members of the natural hazard research community, respondents noted that multi-hazards and resulting risks remain one of the core scientific challenges to be tackled (Sakic Trogrlic et al., 2022).

Subsequently, the past years have seen a rise in compound- and multi-risk (multi-hazard) studies that try to capture some of these complexities through advanced statistical methods (e.g. Zscheischler, 2017; Bevacqua et al., 2022; Couasnon et al., 2020), physically based models (Eilander et al., 2023; Couasnon et al., 2022), and multi-risk system analysis (e.g. Simpson et al., 2022; De Angeli et al., 2022; Van Westen and Greiving, 2017; Gill and Malamud, 2017; Ward et al., 2022). As a result, the compound- and multi-risk communities have developed largely in parallel with each other, and only in recent months have significant efforts been made to bring these two communities together, for example, as demonstrated by the American Geophysical Union (AGU) 2022 session focusing specifically on breaking silos between the two communities.

As early career researchers from both fields, we have contributed to shaping these two communities, and we perceive the need to bring them together to assess solutions for the future. However, despite these advances, there is still no single collection of high-quality scientific research papers focusing on methodological innovations for the analysis and management of both compound and multiple risks.

Humanity’s impact on the Earth, especially the climate and the ocean, constitutes an existential threat of unprecedented magnitude. The consequences are dire, including the loss of life and ecosystems, parts of the Earth being rendered uninhabitable, species extinction, and increased vulnerability to disasters.

Effective education and communication are crucial components of climate and ocean change mitigation and adaptation. By imparting knowledge, reinforcing skills, and fostering awareness, education and communication have the power to enable individuals to understand the complexities of the climate and ocean crisis and its existential implications. Education and communication cultivate a sense of responsibility, motivating individuals to adopt sustainable practices and make informed decisions. Education and communication are closely connected and mutually reinforcing: most forms of education depend on communication, and communication is often educational.

Education needs to equip present and future generations with the skills needed to innovate, develop social justice, and advocate for policy changes. Communication fosters critical thinking, enabling us to challenge harmful practices and embrace environmentally conscious alternatives. Thus, education and communication have a heavy responsibility with respect to creating a knowledgeable and engaged citizenry and laying the foundation for collective action and a sustainable future.

We solicit contributions (e.g. original research articles and review articles) from researchers, practitioners, educators, students, policymakers, communicators, activists, and artists working across different sectors (e.g. academia, industry, and nongovernmental organizations). This will be a unique opportunity to explore and enhance climate and ocean communication and education.

With respect to the scope of this special issue, we welcome research articles that investigate a wide variety of topics, including, but not limited to, the following:

• best practices in and innovative approaches to climate and ocean education and communication;
• the ethics and geoethics of climate and ocean education and communication, including social justice and equity;
• the role of technology (including artificial intelligence) and new media in climate and ocean education and communication;
• the intersection of climate and ocean education and communication with other issues, such as biodiversity, sustainable development, and the Sustainable Development Goals (SDGs);
• the impact of climate and ocean education and communication on public opinion, policy, and behaviour;
• the integration of climate and ocean literacy into formal and informal education;
• the role of geoscience research in advancing climate and ocean education and communication;
• scientific investigation of outreach initiatives targeting different age groups, settings, and approaches;
• learners’ content and procedural knowledge of climate science and options for action (e.g. climate feedbacks, impacts, adaptation measures, and renewable energy), cultivating science and communication skills (e.g. quantitative literacy, critical thinking, and writing to inform), initiating positive attitudes and actions (e.g. empathy and behavioural change), and issues related to the transfer of education into action and to timescales needed for mindset and behavioural change.
