Coastal Communities Ocean Acidification Act of 2022 This bill directs the National Oceanic and Atmospheric Administration (NOAA) to collaborate with state, local, and tribal entities that are conducting or have completed community vulnerability assessments, research planning, climate action plans, or other similar activities related to ocean acidification and coastal acidification and their impacts of ocean acidification on coastal communities. NOAA must (1) support collaborative interagency relationships and information at the state, local , and tribal level; and (2) assist state, local, and tribal entities in improving existing systems and programs to better address ocean acidification and coastal acidification and identify whether such activities can be used as a model for other communities.
