The Impact of Climate Change Across the Cancer Control Continuum: Key Considerations for Oncology Nurses.

Nurses in all specialties have been called upon to take action to address global climate change, climate justice, and health. The American Nurses Association (2023) has specifically tasked nursing professional organizations to (a) educate members on climate change-related illnesses and negative impacts on treatment, (b) collaborate with grassroots organizations for environmental justice efforts, (c) support policies that promote climate mitigation and adaptation, (d) maintain familiarity with climate justice frameworks, and (e) collectively amplify the voice of nursing to strengthen its impact on climate policy. The purpose of this white paper is to enlighten members of the Oncology Nursing Society and oncology nurses at large on the increasing impact of climate change across the cancer control continuum and the pivotal role of the oncology nurse in education, research, clinical practice, and advocacy. Climate change refers to long-term shifts in temperature and weather patterns that are occurring because of global warming (United Nations, n.d.). Climate change is an often-overlooked social determinant of (or contributor to) health that exacerbates poor health, increases healthcare costs, disproportionately affects some communities, and has a synergistic effect with other social determinants of health (Ragavan et al., 2020). Climate change affects all aspects of the cancer control continuum and impacts some populations disproportionately. Events such as wildfires and floods, exacerbated by climate change, can heighten individuals' exposure to cancer-causing substances, thereby increasing their susceptibility to the disease; reducing such exposure can reduce risks for cancer and positively impact the environment. Air pollution, extended droughts, heat waves, ultraviolet radiation, extreme weather events, and food supply disruptions also impact cancer etiology. Extreme weather events disrupt preventive care, cancer detection, and screening efforts, and create workforce shortages that can lead to suboptimal care. Disruptions in the supply chain and scheduled healthcare visits impact patient care continuity. Additionally, climate-related extreme weather events have an impact on overall survival and disrupt end-of-life care, underscoring the pervasive impact of climate change on cancer care across the continuum. Oncology nurses are strategically positioned to contribute to multifaceted solutions, including obtaining and offering education to fellow healthcare providers, students, patients, community members, and policymakers. Oncology nurse scientists are equipped to spearhead the generation of pertinent new knowledge, and nurses in clinical care can play a crucial role in assisting their healthcare system to become carbon net neutral. Oncology nurses must answer the call to actively engage in climate and health advocacy efforts within their own healthcare systems and in the communities where they live, work, and play. Several resources for education and action are shared.
