Health and climate experts are calling on the World Health Organization to officially recognize the climate crisis as a global public health emergency, warning that rising temperatures are increasingly threatening human health worldwide. Scientists say climate change is no longer only an environmental issue but a rapidly growing health emergency affecting millions of people through extreme heat, polluted air, disease outbreaks, and food insecurity.
Researchers highlight that intense heatwaves are causing more heat-related illnesses and deaths, particularly among vulnerable populations such as children, older adults, and outdoor workers. At the same time, worsening air pollution linked to fossil fuel use is contributing to respiratory and cardiovascular diseases across many regions.
Experts also warn that climate change is expanding the spread of infectious diseases such as dengue, malaria, and cholera by altering rainfall patterns and increasing mosquito-friendly environments. Crop failures, droughts, and floods are further increasing the risks of malnutrition and water shortages in vulnerable communities.
Public health specialists argue that declaring a global health emergency would encourage stronger international cooperation, faster policy action, and increased funding for climate adaptation and healthcare preparedness. They emphasize that urgent measures are needed to reduce greenhouse gas emissions, strengthen healthcare systems, and protect communities from escalating climate-related health risks.
