This research investigates environmental communication of initiatives and strategies related to climate change in water-related themes in Oslo. Environmental communication is premised on the assumption that more effective environmental messages communicated by communication experts can positively influence citizens by rethinking and reorienting global, national, and municipal environmental efforts to develop a more persuasive political practice that can rapidly accelerate the pace and scope of social change in adopting climate-friendly lifestyles. Therefore, I analyzed sound online climate strategies and initiatives to curb water-related climate threats in Oslo undertaken by scientists, municipality, and governmental actors. Essentially, I studied how stakeholders used communication strategically and compared analyzed approaches to the theoretical efficiency of such communication.
