Improved capacity of professionals, organizations, and governments to protect populations from the preventable health impacts of extreme ambient heat.

  • The network aims to create a common space to promote evidence-driven interventions, shared-learning, co-production of information, synthesis of priorities, and capacity building that can empower multi-disciplinary actors to take more effective and informed life-saving preparedness and planning measures.

  • It seeks to be a catalyst, knowledge broker and forum for facilitating exchange and identifying needs of the most vulnerable.

How we work

The Network brings together the work and progress of its members to create a holistic picture of the needs, science and strengths across the network to:

  • rapidly scale up efforts to manage the complex human health risks introduced by extreme and increasing ambient heat
  • harmonize and improve information and opportunity sharing across the burgeoning local communities of health professionals, decision makers and scientists motivated to address this issue.


The Network’s programmes and activities help improve the capacity of governments, organizations, and professionals to protect populations from the avoidable health risks of extreme ambient heat.

Members and the wider public benefit from ongoing activities, including:

  • Biannual Global Forum on Heat and Health
  • News, information and knowledge on Heat Health via our online platform, including inventories of Heat Health Action Plans and case studies
  • Country profiles
  • Global Synthesis Reports on Heat Health
  • Learning exchanges

Our members

Diverse expertise and perspectives: Our members self-select, enhancing inclusion of a broad range of organizations and professionals from around the world.

Compatible motivation: The mission and values of our members are expected to be compatible with the GHHIN vision.

Scientific integrity and shared principles: Members will be encouraged to uphold scientific integrity and principles of good public health practice.

This includes organizations and professionals from:

  • government agencies
  • academic institutions
  • international organizations
  • professional associations
  • non-governmental organizations
  • private-sector boundary institutions
  • individuals in relevant fields


The Network functions with a “light touch” governance structure, with plans to establish a Steering Committee and Executive Committee later in 2019.


Following repeated calls for harmonization and improvement of our common understanding and decision tools for the management of the health risks of extreme heat and rising temperatures, the Network was launched in June 2016 by experts from over a dozen founding institutions, spearheaded by the World Health Organization and World Meteorological Organization Joint Office for Climate and Health, and the United States National Oceanic and Atmospheric Administration (NOAA).
