Climate Change and Global Health: Why Experts Are Calling It an Emerging Health Crisis

 

  

Climate change is often discussed as an environmental issue. But increasingly, experts are describing it as a global health concern.

Rising temperatures, changing weather patterns, and environmental disruptions are not just affecting the planet — they are also affecting human health in many ways.

Understanding this connection helps us see why climate change matters beyond the environment.
