A perspective published online October 8, 2026 in the Journal of Investigative Dermatology argues that climate change is reshaping dermatologic practice faster than the specialty is preparing for, with measurable consequences for disease incidence, severity, and care access worldwide.

The piece, "The impacts of climate change on global skin health: Considerations for dermatologic disease burden, equity, and care delivery," was authored by Eva Rawlings Parker of Vanderbilt University Medical Center and Olufolakemi Cole-Adeife, and appears as a mini-review under a Creative Commons license (DOI: 10.1016/j.jid.2026.07.026). It carries the framing the authors intend bluntly: climate change is the greatest global health threat of the 21st century, and no specialty has more at the clinical interface than dermatology.

What does the paper actually argue?

Parker and Cole-Adeife position the skin as a direct sensor of the external environment. Heat, humidity, precipitation patterns, storms, drought, air pollution, and ecological disruption all act as climate-sensitive drivers of skin disease. Because dermatologists read those signals at the bedside daily, the authors argue, the specialty carries an obligation to respond not just clinically but across surveillance, research, advocacy, and education.

They frame that response as the integration of "planetary health" principles into the field.

Which skin conditions are climate-linked?

The review groups the impact into three disease buckets and a cross-cutting concern:

• Infectious skin diseases, including vector-borne diseases (VBDs), neglected tropical diseases (NTDs), and the cutaneous manifestations seen in people living with HIV (PLHIV), tied to shifting vector ranges and disrupted mass drug administration (MDA) programs.
• Autoinflammatory conditions, with atopic dermatitis (AD) as the leading example, whose flares track heat, humidity, and ambient pollution.
• Neoplastic disease, including nonmelanoma skin cancer (NMSC), connected to rising ultraviolet exposure and outdoor labor patterns.
• Antimicrobial resistance (AMR), woven through the infectious-disease discussion because warming and flooding accelerate resistant-organism spread.

How does climate change disrupt dermatologic care delivery?

Extreme weather events (EWEs) interrupt clinic operations, drug supply chains, and the cold-chain logistics on which biologic therapies depend. In low- and middle-income countries (LMICs), where WASH (water, sanitation, and hygiene) infrastructure is already strained, the authors argue these disruptions translate directly into worse outcomes.

They also flag a workforce gap. Dermatologists in heavily affected regions are scarce, and when storms or heat waves hit, specialty access collapses first. The paper frames this as both a continuity-of-care problem and an equity problem.

Who is most exposed?

The paper identifies four overlapping vulnerable groups, weighted by exposure and access loss:

• Communities in the Global South
• Low-income urban and rural populations
• Outdoor laborers, including agricultural and construction workers
• Climate-displaced persons

Outdoor workers carry occupational UV and heat contact; climate-displaced persons often lose any remaining dermatology capacity in the post-disaster window. The two effects compound.

What should dermatologists do next?

Parker and Cole-Adeife call for embedding planetary health principles into clinical practice, disease surveillance, research funding, and graduate medical education. They argue the specialty's visibility advantage — patients arrive with disease that can be photographed, measured, and tracked — should translate into advocacy on greenhouse gas (GHG) reduction alongside skin-cancer prevention.

The perspective stops short of specifying curricula, advocacy channels, or reimbursement pathways. That implementation detail, the authors implicitly concede, is for individual institutions and societies to design.

What happens next?

With the paper now indexed in JID under open access, the test will be whether the broader dermatology community — residency programs, the American Academy of Dermatology, and the International League of Dermatological Societies — adopts the planetary health framework Parker and Cole-Adeife propose, or treats the perspective as conceptual without operational follow-through. Either outcome will shape how the specialty prepares for the dermatologic load the next decade is forecast to bring.
