WHO Urged to Declare Climate Change a Public Health Emergency Amidst Intensifying El Niño and Rising Fatalities
Public health researchers and professionals are urgently calling for the World Health Organization (WHO) to declare the health impacts of climate change a Public Health Emergency of International Concern (PHEIC). This appeal comes as the world faces an unprecedented El Niño season, with a recent report forecasting 451,000 additional heat-related deaths from June 2026 to February 2027, a figure comparable to COVID-19 fatalities in the first six months of the pandemic. Extreme climate events, including heatwaves, floods, and wildfires, have already caused significant loss of life and displacement globally, with over 50,000 heat-related deaths reported in European cities last summer, over 65% directly attributable to climate change. The WHO's International Health Regulations provide a mechanism for such a declaration, which would galvanize political will, mobilize financing, and provide evidence-based recommendations for an urgent public health response.
