About YCCCH
Climate change is the greatest public health challenge of the 21st century, with far-reaching impacts already evident and potentially catastrophic risks ahead. It contributes to rising illness and death from extreme heat, natural disasters, infectious diseases, food insecurity, respiratory illness, and conflict-driven displacement. Yet, addressing climate change also presents a major health opportunity. Reducing greenhouse gas emissions can improve air quality, promote healthier diets, encourage physical activity through sustainable infrastructure, and lessen occupational and environmental hazards—advancing both planetary and human health.
