Climate change is altering US marine ecosystems in unprecedented ways, leading to shifts in species’ location, productivity, and seasonal timing. This poses risks to fisheries, tourism, recreation, transportation, energy, and other economic sectors—and also undermines critical connections between people and the ocean, especially within Indigenous communities. Swift implementation of equity-focused adaptation and mitigation could help limit future risks.

    Key points:

  • Unprecedented Climate Impacts Threaten Ecosystems and Human Well-Being
  • Climate Change Is Altering Marine-Related Economic Activities
  • Our Future Ocean Depends on Decisions Today
