More than 100 international health organizations are urging the World Health Organization (WHO) to formally declare the climate crisis a global public health emergency. In a joint statement released this week, medical professionals, researchers, and public health advocates emphasized the escalating toll of climate change on human health, citing increased heat-related deaths, respiratory illness from air pollution, and the spread of vector-borne diseases. The appeal comes ahead of the upcoming World Health Assembly, where global health priorities are set.
Immediate Health Risks Escalate
The declaration is backed by mounting evidence linking climate change to worsening health outcomes worldwide. According to the WHO, climate-related factors contribute to over 13 million deaths annually, primarily through malnutrition, extreme heat, and polluted air. Recent heatwaves across Southern Europe and South Asia have overwhelmed hospitals, while intensified wildfires have degraded air quality across North America. The WHO has previously identified climate change as the greatest health threat of the 21st century.
Scientific Consensus and Institutional Support
The call echoes years of scientific consensus that climate change directly undermines public health infrastructure. Studies published in The Lancet have shown that rising global temperatures expand the habitats of disease-carrying mosquitoes, increasing risks of dengue, malaria, and Zika virus. Additionally, food and water insecurity driven by droughts and floods disproportionately affect vulnerable populations, especially in low-income nations. Medical associations from over 40 countries have now endorsed the emergency designation.
What to Watch
The WHO is expected to address the petition during its annual assembly in May, where member states will debate potential resolutions on climate and health. While the organization has not yet committed to a formal emergency declaration, Director-General Tedros Adhanom Ghebreyesus has repeatedly stressed the health impacts of environmental degradation. An official designation could unlock emergency funding, prioritize climate-health research, and strengthen global coordination in public health planning.
