We Track That
We partner with the Climate and Health Program to host data from several sources to track the effects of climate change and help communities respond. The Tracking Network also collects data on heat-related illnesses throughout the United States and provides information so people can protect themselves.
Types of Data
The Tracking Network provides data about extreme heat, heat-related health effects, and the vulnerabilities that increase risk for health effects related to those events.
Data in Action
Reviewing these national data helps scientists make comparisons between environmental conditions and health problems. Specifically, uses of extreme heat data include:
