The effects of climate change over the coming years are anticipated to pose a significant threat to public and environmental health, with certain areas already experiencing environmental and health effects linked to this crisis. It is estimated that the Earth’s temperature over the last century has increased 1.5 degrees Fahrenheit, with projections only increasing in coming centuries[i]. The rise in Earth’s temperature, resulting from emissions and elevated concentrations of greenhouse gases in the atmosphere, is contributing to a changing climate. Human activity, such as burning fossil fuels, including methane, carbon dioxide, and nitrous oxide for energy production and use, transportation, industry (including healthcare), and agriculture have resulted in unprecedented levels of greenhouse gas emissions. The science is clear that human activity is the dominant cause of Earth’s rising temperature and without immediate action irreversible damage is likely.[ii]
As a result of rising temperatures, changing and variable weather patterns are occurring, such as extreme temperatures both heat and cold, rises in sea level from melting of snow and ice, changes in precipitation resulting in flooding and drought, more intense hurricanes and storms, wildfires, as well as poorer air quality. Changes to climate patterns lead to current and imminent threats to public and environmental health with growing evidence and concern about impacts on human health noted if action is not taken.
Nurses’ Role in Addressing Climate Change
The Alliance of Nurses for Healthy Environments has partnered with ecoAmerica (eA) and Climate for Health (CfH) in supporting a Nursing Collaborative on Climate Change and Health which aims to join national nursing organizations and to elevate nursing leadership in addressing climate change. With support by national organizations representing nurses across differing specialties, there is great potential to bring a health-focused discussion to national climate change policy, regulations and initiatives. ANHE’s aim is to inspire nurses to be leaders in helping our patients, our communities, and our healthcare institutions engage in climate change mitigation activities and in preparing for potential effects of climate change. If your organization would like to join the Nursing Collaborative please contact Cara Cook at cara@enviRN.org.

Climate Change and Health
Greenhouse gas emissions and subsequent pollution have resulted in changes to the climate that contribute to negative health impacts. Health impacts include increases in infectious disease transmission, extreme weather event related morbidity and mortality, and reductions in food supply and displacement of populations as a result of increases in flooding and droughts.[iii] There are also significant consequences associated with air quality deterioration resulting from burning fossil fuels, coal combustion, and increasing levels of pollutants, ground-level ozone, and particulate matter. Increased carbon emissions contribute to worsening rates of heart disease, cancer, stroke, chronic respiratory disease and asthma, and elevated atmospheric levels of ozone and particulate matter are associated with increased vulnerability to respiratory and cardiovascular diseases, and preterm birth.[iv]
Certain populations will be extremely vulnerable to health impacts associated with climate changes including children, the elderly, low-income populations, and individuals with chronic health conditions. Additionally, with the range of climate regions across the United States, climate change will pose variable risks throughout the country.

Climate Change Adaptation and Mitigation: Action for Nurses
Adoption of both climate adaptation and mitigation strategies are necessary to protect the health of the public against the negative impacts of climate change. Climate adaptation strategies include preparing for and responding to threats posed by climate change, whereas mitigation strategies aim to eliminate or reduce threats. Adaptation strategies are necessary to ensure community and healthcare institution preparedness in adapting and responding to impacts resulting from climate change. Mitigation is necessary to halt further warming of the Earth and worsening climate patterns.
To ensure communities and healthcare facilities are prepared for impacts of climate change, including natural disasters and flooding, nurses can work with local and state health departments and healthcare facilities to ensure that disaster preparedness plans and training are in place in the event of disruption in community infrastructure or health services. Nurses can further facilitate the development of statewide climate adaptation plans and action plans for extreme temperature events to ensure that people have access to necessary care.
There is still a great amount of work to be done in the healthcare sector to mitigate the effects of climate change. The healthcare industry accounts for 8% of the total carbon dioxide emissions in the United States.[v] Nurses can work within institutions to reduce the use of fossil fuels by promoting energy efficiency in operations and building design, along with encouraging the use of clean energy when possible. Hospitals can utilize purchasing power to purchase healthy and environmentally sustainable foods to serve to staff and patients to promote health and reduce their carbon footprint. For further information on what can be implemented in healthcare institutions to reduce their environmental impact visit Health Care Without Harm’s website to learn more about their Global Green and Healthy Hospital’s Network and other initiatives.
Further areas to address climate and health impacts needing nursing involvement include developing assessment tools to assess environmental impacts on health, assisting in research efforts to further the science on climate and health, and furthering education of fellow nurses, health professionals, patients, policy makers, and the public on climate change and strategies to reduce impacts. Nurses can also advocate for public-health backed policy and ensure that health is placed at the forefront of decision making as it relates to climate and health.

How to Communicate about Climate and Health
In order to convey the message of how climate change affects health and the urgency to act now to prevent worsening impacts, nurses should understand how to effectively communicate with patients, colleagues, policy makers, and the public. It is important to frame your message around how climate change will affect human and public health, rather than focusing solely on the changes to the environment. It is also essential to focus not only on the problem, but to offer solutions to how the issue can be addressed through education on adaptation and mitigation strategies. There are numerous resources available to assist nurses and other health professionals with communicating about climate and health. Here are a few resources to get you started on opening up the conversation:
