The Global Heat Health Information Network is a collaborative initiative founded in 2016 by prominent organizations, including the World Meteorological Organization (WMO), World Health Organization (WHO), and the US National Oceanic and Atmospheric Administration (NOAA). This dynamic network unites policymakers, scientists, and practitioners committed to mitigating the health risks associated with extreme heat globally. Its mission is to catalyze action by connecting diverse stakeholders, advancing scientific understanding, and informing effective policy measures.

The network offers comprehensive resources, including e-learning courses, masterclasses, and access to an expert directory. Regional hubs in South Asia and Southeast Asia enhance localized responses to heat challenges, while key activities encompass scientific synthesis reports and public health advice on heat management. Through collaborative forums and targeted outreach efforts, the network aims to empower communities, improve their capacity to respond to environmental conditions, and ensure that no one is left vulnerable due to extreme weather impacts. Ultimately, it strives to build a world where extreme heat does not hinder lives or livelihoods.
