The Global Heat Health Information Network is an independent, voluntary, and member-driven forum of scientists, practitioners, and policy makers focused on improving capacity to protect populations from the avoidable health risks of extreme heat in our changing climate.

The solution-based network promotes the sharing of resources, learning, and information to enhance technical and science based decision tools to better manage heat risks, and encourages collaborative learning and partnership building between members to accelerate good practice.

Our Vision

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 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 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:

5 Pillars of Integrated Heat Health Action

Our Networks’ 5 Pillars of Integrated Action support coordinated information and action to reduce the impact of heat on health worldwide.

5 Pillars of Integrated Heat Health Action 

Pillar and RationaleNetwork RolePriority Issues
1. Partnerships and Capacity Building

To address the multifaceted and multidimensional risks extreme heat poses for health, building capacity to develop and drive diverse partnerships from global and local levels is critically needed.
The Network supports interdisciplinary capacity building and collaboration at local to global levels, including through human and institutional training opportunities, inter-institutional and interdisciplinary coordination and partnerships.

  • Institutional capacity;
  • Partnerships;
  • Training;
  • Coordination models
2. Heat Vulnerability and Impact Science

Data, science, and research are needed to understand the health risks of heat in our changing climate.
The Network supports actions (methods, data, research) that enhance knowledge on human vulnerability and impacts of extreme ambient heat, including heat impact metrics, surveillance systems, research and operational systems for monitoring and modelling heat-health risks, research and knowledge gaps. Tool tip Find out more about heat and health
  • Vulnerability studies;
  • Impact metrics and surveillance;
  • Impact Thresholds;
  • Epidemiological Studies;
  • Physiological studies;
  • Cascading environmental risk modelling;
  • Research gaps
3. Heat Prediction and Services

Accurate and timely climate and weather information is necessary to enable effective decision making and action to protect health and save lives.
The Network supports actions (research, methods, and observations) behind the data, forecasts, and information required for operational heat risk monitoring and prediction across timescales, including epidemiological impact forecasting; Urban Heat Island monitoring and modelling; and operational early warning systems. Tool tip Find out more about when and where heat is dangerous, and how it's measured and monitored.

  • Preparedness;
  • Mitigation;
  • Evaluation
5. Communications and Outreach

Effective risk communication and outreach play a key role improving awareness of the risk that hot weather poses to human health, wellbeing, and productivity worldwide.
The Network supports the identification of key messages and good practices for increasing awareness and communicating heat health risks to diverse audiences and various audiences including clinical medicine, public health, urban planning, academia, and meteorology. Tool tip Find out more about advocacy and risk communications for heat health.

The Network was initiated in June 2016 by experts from over a dozen founding institutions, 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 officially launched with a call to action in December 2018 at the First Global Forum for Heat and Health. It is 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).
