From Siloed Interventions to Structural Solutions: Climate Change as a Test Case for a New Public Health Paradigm

Area of Science:

• Public Health
• Environmental Health
• Health Systems Research

Background:

• Traditional public health interventions are insufficient for complex crises like climate change.
• Climate change necessitates a systemic reconceptualization of public health.
• Health is an emergent property of interconnected social, economic, and environmental systems.

Purpose of the Study:

• To argue that climate change is a paradigmatic challenge for public health.
• To advocate for upstream, structural interventions addressing multiple health outcomes.
• To reorient public health policy toward root-cause solutions.

Main Methods:

• Perspective piece drawing on existing literature and examples.
• Analysis of limitations in traditional public health approaches.
• Integration of insights from mental health, political economy, and environmental justice.

Main Results:

• Siloed, problem-specific solutions are inadequate for climate-related health crises.
• A systemic approach is required to address the complex, interdependent nature of climate and health.
• Prioritizing people over profit and collective responsibility is essential for managing shared risks.

Conclusions:

• Climate change requires a fundamental shift in public health strategy toward structural interventions.
• Public health must address the root causes of health inequities exacerbated by climate change.
• Reorienting policy to address environmental and social determinants is critical for population health resilience.
