There is an urgent call for nurses to address climate change, especially in advocating for those most under threat to the impacts. Social justice is important to nurses in their relations with individuals and populations, including actions to address climate justice. The purpose of this article is to present a Global Nurse Agenda for Climate Justice to spark dialog, provide direction, and to promote nursing action for just‐relations and responsibility for planetary health. Grounding ourselves within the Mi'kmaw concept of Etuaptmumk (...) (two‐eyed seeing), we suggest that climate justice is both call and response, moving nurses from silence to Ksaltultinej (love as action). We review the movement for climate justice in nursing, weaving between our own stories, our relations with Mi'kmaw ways of knowing, and the stories of the movement, with considerations for the (w)holistic perspectives foundational to nursing's metaparadigm of person, environment, and health. We provide a background to the work of the Global Nurse Agenda for Climate Justice steering committee including their role at the 26th United Nations Climate Change Conference in Glasgow, 2021, and share our own stories of action to frame this agenda. We accept our Responsibility for the challenges of climate justice with humility and invite others to join us. (shrink)
