Human health and climate change are intricately linked, with climate and environmental changes already impacting various aspects of human health. To improve the health of our communities, we all must embrace, understand, and advocate for this issue.
Several health trends are directly linked to the changing environment. As global temperatures rise, and more frequent and intense temperature fluctuations continue, heat-related illnesses become more common, especially in areas not traditionally impacted by heat waves. For example, warmer temperatures and altered precipitation patterns expand the geographic range of diseases like malaria, dengue fever, and Lyme disease.
Physicians can combat climate change by leveraging their expertise and influence through various avenues. Many doctors and public health workers actively engage in research, which can inform evidence based public health interventions. Some physicians work with scientists, engineers, policymakers, and community leaders to develop holistic solutions integrating health considerations into climate action plans.
If you encounter someone who doubts the impact of climate change on human health, here are some key points you can use to communicate the evidence and consensus among scientists and health professionals. Most climate scientists and health experts agree that climate change already affects human health, supported by extensive evidence-based research and data. Direct observable impacts can be clearly seen in the epidemiologic data. Encourage the skeptic to explore credible sources of information on climate change and health, such as scientific literature, reports from reputable organizations, and educational resources. Perhaps most impactful are personal stories or local examples of how climate change affected the health of your patients. You may not convince a skeptic in a single conversation, but you can open the dialogue.
Addressing climate change is essential not only for environmental sustainability but also for safeguarding human health and well-being. Mitigation efforts to reduce greenhouse gas emissions, adaptation strategies to cope with changing conditions, and investments in public health infrastructure are vital. Physicians must be actively engaged and lead many of these efforts to ensure the health of communities, protect public health, and ultimately promote a healthier and more sustainable future for all.
