Climate change and health: three grand challenges

Area of Science:

• Environmental Health
• Public Health Policy
• Climate Science

Background:

• Climate change poses significant direct and indirect threats to global health.
• It undermines essential environmental and social determinants of health.
• Urgent decarbonization and resilience-building are critical for human well-being.

Purpose of the Study:

• To outline a comprehensive health response to climate change.
• To identify key challenges and actions for the health sector.
• To emphasize the role of the health community in climate advocacy and action.

Main Methods:

• The study synthesizes current understanding of climate change impacts on health.
• It proposes a framework for health system adaptation and mitigation.
• It highlights the health sector's potential for leadership and inter-sectoral guidance.

Main Results:

• The health response to climate change can be structured around three core challenges: promoting co-benefits, building resilient health systems, and implementing public health measures.
• The health community has a vital role in advocacy, evidence provision, and guiding other sectors.
• Decarbonizing healthcare systems is a key component of the response.

Conclusions:

• Addressing climate change requires a multi-faceted health strategy focused on mitigation and adaptation.
• The health sector is uniquely positioned to lead climate action and advocate for policy change.
• Investing in climate-resilient and low-carbon health systems is essential for safeguarding public health.
