Introduction

Climate change is a health issue that affects morbidity, mortality, and society’s abilities to deliver healthcare and support healthy living.  The effects of climate change are already harming human health around the world, and impacts will only intensify in the coming years. Heat waves and rainstorms are becoming more deadly, disease outbreaks last longer and are seen in new regions, wildfire smoke from tinder-dry forests reduces air quality, and food and water security are threatened by extreme weather. Moreover, climate change exacerbates the global epidemic of noncommunicable diseases (NCDs), with disrupted services following extreme weather events and declining food security leading to poor nutrition and associated health risks. Shifting to sustainable practices, such as plant-based diets and alternative transportation, can offer significant co-benefits to both health and the environment.

There is an imperative for quick action on many fronts: to recognize and respond to climate-health threats; prevent climate change at its source by reducing heat-trapping greenhouse gas emissions; support “greener” systems throughout the economy, including healthcare; understand the health co-benefits of adaptation and mitigation; and communicate effectively about these issues to safeguard human health. 

To meet these challenges, current and future nursing professionals globally must understand the dynamics governing the interactions of climate and health, the level of scientific understanding of those interactions, and potential adaptation, mitigation, and resilience-building solutions, while carrying a respect for the processes and issues not yet fully understood.  Furthermore, the nursing profession needs to be able to apply these principles to individual and population level health needs to devise individual and locally meaningful public health solutions. Education is key in the effort to increase knowledge and skills among nursing professionals, clinicians, public health practitioners, emergency responders, educators, healthcare leaders, and policy makers in order to build capacity and so they may continue to serve as trusted voices within their professions and institutions.
