Marine Ecosystems
Climate change is altering U.S. 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.
- Unprecedented climate impacts threaten ecosystems and human well-being.
- Climate change is altering marine-related economic activities.
- Our future ocean depends on decisions today.
