Ocean acidification (OA) occurs when carbon dioxide (CO2) dissolves into oceans. OA and climate change are both caused by anthropogenic CO2 emissions, and many scientists consider them equally critical problems. We assess if preexisting beliefs, ideologies, value predispositions, and demographics affect OA perceptions among the U.S. public. Nearly 80% of respondents know little about OA, but concern increased following a message explaining OA and climate change, especially among females, liberals, and climate change believers. OA information seeking intentions and research support were also greater among females, liberals, and climate change believers. We discuss implications for efforts to increase OA public awareness.
