This expert report examines the resilience of marine ecosystems to climate change, defining resilience as the capacity of systems to absorb, reorganize, and adapt while maintaining essential functions. It details how the "deadly trio" of ocean warming, acidification, and deoxygenation, combined with sea-level rise, assaults crucial ecosystems like coral reefs, kelp forests, and polar regions. The report emphasizes biodiversity, functional redundancy, genetic diversity, and connectivity as critical pillars of marine resilience. It concludes that while local management strategies like Marine Protected Areas and active restoration are vital, drastic global greenhouse gas mitigation is ultimately necessary to prevent irreversible ecosystem collapse and safeguard the immense socio-economic value of the global "Blue Economy."
