This study provides valuable insights into the relationship between climate change psychological distress and collective action. However, some aspects could benefit from further clarification. Could the authors elaborate on the potential bidirectional nature of the relationship between distress and action? For instance, to what extent might engagement amplify distress, as opposed to distress driving action? Additionally, the measures focus on depression and anxiety—how might other emotions, such as eco-grief or anger, influence collective action differently? Lastly, how might cultural or regional differences impact the findings, given the U.S.-centric nature of the study? Addressing these points could provide greater context to the findings.
