University of Miami-Led Research Highlights Climate Impacts on Oncology
A groundbreaking study from the University of Miami Sylvester Comprehensive Cancer Center has illuminated how rising temperatures are already altering the daily realities and medical choices of cancer patients in one of the nation’s hottest regions. Published in Environmental Research: Climate, the research draws on qualitative insights from patients, caregivers, and providers to document a range of adaptations forced by extreme heat.
The work underscores the intersection of climate science, oncology, and public health, areas where University of Miami faculty and students are increasingly active. As heat waves intensify across the United States, institutions like the Miller School of Medicine and the Rosenstiel School of Marine, Atmospheric, and Earth Science are positioned at the forefront of interdisciplinary inquiry that directly informs patient care and policy.
Context of Extreme Heat in South Florida and Beyond
South Florida experiences some of the most prolonged and intense heat periods in the country, with urban heat islands amplifying risks for vulnerable populations. Cancer patients, many of whom face compromised immune systems, mobility limitations, or financial strain, encounter additional barriers when temperatures soar. The study situates these challenges within a national trend of increasing heat-related health burdens documented by federal agencies.
University researchers note that climate stressors compound existing disparities in access to care, particularly for communities already navigating transportation, housing, and economic hurdles. This regional focus provides a laboratory for understanding broader U.S. implications as heat patterns shift northward and westward.
Core Findings on Patient Decision-Making
Participants described retreating indoors during peak heat hours, rescheduling appointments, and altering treatment regimens to avoid outdoor exposure. Some reported delaying chemotherapy or radiation sessions when travel became untenable, while others weighed the risks of missed doses against the dangers of heat exhaustion.
Financial pressures emerged as a recurring theme, with higher utility costs for air conditioning straining household budgets already stretched by medical expenses. Caregivers often assumed additional logistical burdens, coordinating rides or home modifications to maintain treatment continuity.
Provider Perspectives and Clinical Adaptations
Clinicians at Sylvester reported adjusting infusion schedules, expanding telehealth options, and incorporating heat-safety counseling into routine visits. The study highlights the need for oncology teams to integrate climate resilience into standard protocols, a shift that many academic medical centers are now exploring through dedicated working groups.
Interviews revealed gaps in existing infrastructure, including limited cooling centers near treatment facilities and inconsistent guidance on recognizing heat-related complications in immunocompromised patients. These observations point to opportunities for targeted training programs within nursing and medical curricula.

Methodology and Scope of the Research
Researchers employed in-depth interviews and focus groups with a diverse cohort of cancer patients, family members, and healthcare providers across Miami-Dade and Broward counties. The qualitative approach allowed nuanced exploration of lived experiences that quantitative data alone cannot capture.
Collaboration across the Miller School, Rosenstiel School, and School of Nursing and Health Studies enabled integration of atmospheric science, epidemiology, and health equity perspectives. The resulting publication in Environmental Research: Climate marks a notable contribution to the growing literature on climate and non-communicable diseases.
Implications for U.S. Higher Education and Research
The University of Miami study exemplifies how academic institutions can leverage regional strengths to address national priorities. Faculty and graduate students in climate science, oncology, and public health are gaining valuable experience in community-engaged research that translates directly into improved patient outcomes.
Funding agencies and foundations increasingly prioritize interdisciplinary work at the climate-health nexus, creating new pathways for postdoctoral fellows and early-career investigators. Departments seeking to expand their portfolios in these areas may find models in Miami’s approach to partnership building with local health systems.
Broader National and Policy Context
Across the United States, extreme heat events are rising in frequency and severity, affecting rural and urban populations alike. Cancer centers in other heat-prone states are beginning to examine similar questions, suggesting the Miami findings could inform a wider network of adaptation strategies.
Policy discussions at the federal level, including those involving the National Cancer Institute and Centers for Disease Control and Prevention, increasingly reference climate resilience. University-led studies provide the evidence base that shapes these conversations and subsequent resource allocation.
Challenges for Patients, Providers, and Institutions
Key obstacles include inconsistent access to reliable cooling, transportation barriers during heat advisories, and the absence of standardized heat-safety protocols in oncology settings. Economic disparities amplify these issues, with lower-income patients facing the steepest trade-offs between treatment adherence and personal safety.
Academic medical centers must also contend with infrastructure limitations, staffing shortages during peak summer months, and the need for ongoing professional development on climate-related health risks. These systemic challenges require coordinated responses across university leadership, clinical operations, and community partners.

Future Outlook and Emerging Research Directions
The University of Miami team plans follow-up studies that quantify the frequency of heat-driven care disruptions and evaluate intervention effectiveness. Expanded geographic scope and longitudinal designs could strengthen the evidence base for national guidelines.
Graduate programs in environmental health, nursing, and climate policy stand to benefit from increased demand for professionals equipped to navigate these intersections. Universities investing in cross-disciplinary centers and certificate programs may gain a competitive edge in attracting both students and external funding.
Actionable Insights for Stakeholders
Healthcare providers can begin by incorporating brief heat-risk assessments into intake processes and offering flexible scheduling during heat waves. Administrators at cancer centers might prioritize cooling infrastructure upgrades and partnerships with local transit agencies.
Academic leaders interested in similar work can review the open-access publication and reach out to the Miami team for collaboration opportunities. Job seekers in research, clinical, and policy roles should monitor postings that emphasize climate resilience and health equity competencies.
