Résumé
Marine ecosystems play a crucial role in supporting societal needs and human well-being by providing resources like food, carbon storage, coastal protection, and recreational opportunities. However, the impact of climate change on marine biodiversity and ecosystem functioning is a significant concern. The ocean acts as a sink for heat, CO2, and waste, mitigating climate change, but this also alters its chemical composition. Simultaneously, the ocean faces a biodiversity crisis, with over-exploited fisheries and unprecedented rates of environmental change. These twin threats fundamentally affect marine biological systems and the services they provide. Currently, there is little connection between climate change and biodiversity research, particularly in the marine context. Uncovering the nexus between marine biodiversity and climate is crucial for understanding the impacts of climate change on ocean ecosystems. By improving observational capacity, advancing modelling capabilities, and integrating theory, such studies can have a profound impact on local, regional and global ocean governance, and particularly with respect to pollution control, ocean health, and the management of marine resources from fisheries to mineral exploitation.
