A psychologically wise intervention to inform relational organizing in the face of climate and ocean change
Jennifer L. Waldo, Thomas C. Swearingen, Megan Siobhan Jones
2025, npj Ocean Sustainability (4)
Widespread climate action is broadly recognized as necessary to reduce climate change impacts on oceans (“ocean change”), but threats to ocean ecosystems are commonly perceived as distant, irrelevant, and unchangeable. Communicating about ocean change, therefore, requires message framing strategies targeting evidence-based psychological precursors to behavior. In a pre-registered case study...
