Climate Change Background
The overall health of the ocean and national marine sanctuaries will be impacted by climate change. National marine sanctuaries and monuments must contend with rising water temperatures and sea levels, water that is more acidic and contains less oxygen, shifting species, and altered weather patterns and storms.
Climate Change and Your National Marine Sanctuaries
Discover how climate change is affecting our nation’s underwater treasures, what the NOAA Office of National Marine Sanctuaries is doing about it, and how you can help.
National marine sanctuaries and partner organizations monitor ocean conditions and assess the impacts of a changing climate on ecosystems and coastal communities. Sanctuaries serve as sentinel sites where the impacts of climate change and ocean acidification can be studied.
Sanctuary Climate Change Impact Profiles
The impacts of climate change are intensifying both globally and locally, threatening America’s physical, social, economic, and environmental well-being. Explore how each sanctuary and monuments in the national marine sanctuary system is being, and is projected to be, affected by climate change.
Blue Carbon in Marine Protected Areas: A Guide to Understanding and Increasing Protection of Blue Carbon
These "blue carbon" ecosystems help mitigate climate change and its impacts by facilitating the uptake of atmospheric carbon dioxide (CO2) into the ocean and transporting carbon into sediments or deep waters, where it can remain indefinitely if undisturbed.
Blue Carbon in Marine Protected Areas: A Blue Carbon Assessment of Greater Farallones National Marine Sanctuary
The study, conducted by Greater Farallones Association for Greater Farallones National Marine Sanctuary, assessed two coastal blue carbon habitats, seagrasses and salt marshes, and two oceanic carbon sequestration processes, kelp exports and whale deadfalls.
Blue carbon is the term for carbon captured by the world's ocean and coastal ecosystems. Coastal and marine ecosystems play a significant role in the global carbon cycle, sequestering and storing carbon over long timescales.
What is the Carbon Cycle?
The carbon cycle is nature's way of recycling carbon atoms. Carbon is the foundation for all life on Earth.
From supercomputers and state-of-the-art models to observations and outlooks, we provide data, tools, and information to help people understand and prepare for climate variability and change.
