EPA Identifies Ocean Acidity as Climate Change Indicator

The ocean plays an important role in
regulating the amount of carbon dioxide in the atmosphere. As atmospheric
concentrations of carbon dioxide rise
(see the Atmospheric Concentrations of
Greenhouse Gases indicator on p. 16),
the ocean absorbs more carbon dioxide.
Because of the slow mixing time between

Acidification of the oceans need world attention

Remember what it’s like to hold your breath, your lungs demanding fresh air with increasing urgency?
That awful sensation isn’t about lack of oxygen, but is a signal of a dangerous carbon dioxide level. This same CO2 is swiftly changing the chemistry in the earth’s oceans at a rate that would kill you if

Clallum County board briefed on ocean acidification

PORT ANGELES — It would take a global reduction in carbon dioxide emissions to reverse the effects of ocean acidification, members of the Clallam County Marine Resources Committee told county commissioners Monday.
But there are ways to help at the local and state level — pollution control, a reduction in stormwater runoff and investment

The Limits of Water Quality Criteria

Since the beginning of the industrial
revolution, the global ocean has absorbed a third of the carbon dioxide
emissions from fossil fuels, transforming it into carbonic acid. The acidity of
the marine environment has increased by roughly
a third since 1750, changing chemical processes
vital to life, including shell and

Coral Reefs and Shellfish Battle Acidifying Oceans

Slip beneath the water's surface and you'll find a world teeming with life. Schools of yellowtail fish dart through colorful coral reefs. Spiny lobsters emerge from the crevices of ocean rocks searching for a tasty meal. And sea anemones nestle in the nooks of oyster beds.

Scientists are learning more about how carbon dioxide is

The NOAA Ocean Acidification Program (OAP) works to prepare society to adapt to the consequences of ocean acidification and conserve marine ecosystems as acidification occurs. Learn more about the human connections and adaptation strategies from these efforts.

Adaptation approaches fostered by the OAP include:


Using models and research to understand the sensitivity of organisms and ecosystems to ocean acidification to make predictions about the future, allowing communities and industries to prepare


Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes


Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally


On the Road

Drive fuel-efficient vehicles or choose public transportation. Choose your bike or walk! Don't sit idle for more than 30 seconds. Keep your tires properly inflated.

With your Food Choices

Eat local- this helps cut down on production and transport! Reduce your meat and dairy. Compost to avoid food waste ending up in the landfill

With your Food Choices

Make energy-efficient choices for your appliances and lighting. Heat and cool efficiently! Change your air filters and program your thermostat, seal and insulate your home, and support clean energy sources

By Reducing Coastal Acidification

Reduce your use of fertilizers, Improve sewage treatment and run off, and Protect and restore coastal habitats

You've taken the first step to learn more about ocean acidification - why not spread this knowledge to your community?

Every community has their unique culture, economy and ecology and what’s at stake from ocean acidification may be different depending on where you live.  As a community member, you can take a larger role in educating the public about ocean acidification. Creating awareness is the first step to taking action.  As communities gain traction, neighboring regions that share marine resources can build larger coalitions to address ocean acidification.  Here are some ideas to get started:

  1. Work with informal educators, such as aquarium outreach programs and local non-profits, to teach the public about ocean acidification. Visit our Education & Outreach page to find the newest tools!
  2. Participate in habitat restoration efforts to restore habitats that help mitigate the effects of coastal acidification
  3. Facilitate conversations with local businesses that might be affected by ocean acidification, building a plan for the future.
  4. Partner with local community efforts to mitigate the driver behind ocean acidification  – excess CO2 – such as community supported agriculture, bike & car shares and other public transportation options.
  5. Contact your regional Coastal Acidification Network (CAN) to learn how OA is affecting your region and more ideas about how you can get involved in your community
