The document discusses the Sixth Assessment Report from the IPCC Working Group II on impacts, adaptation, and vulnerability. It highlights that climate change is altering marine environments and mechanisms. Many adaptations are available and effective for addressing ocean impacts. The most options are preserved through rapid mitigation and ambitious climate action, along with effective adaptation involving institutions, technology, and nature-based solutions.
