As global temperatures reach record levels, healthcare professionals must understand three interconnected threats reshaping clinical practice. First, heat-related illness will increase substantially, requiring enhanced emergency protocols and expanded capacity for heat-stress management. Second, vulnerable populations—elderly patients, children, and those with chronic disease—face disproportionate risks and require targeted preventive strategies and care planning.
Third, healthcare systems themselves must achieve climate resilience. This means developing contingency plans for infrastructure disruptions, supply chain vulnerabilities, and surge capacity during extreme weather events. Facilities must assess physical vulnerabilities to heat and flooding, establish backup power systems, and ensure medical supply resilience.
For clinicians, this translates to practical action: integrate climate health competencies into patient care conversations, identify high-risk populations in your practice, and participate in institutional climate adaptation planning. Healthcare providers are frontline defenders against climate-related health threats and key architects of resilient health systems.
