Climate Change

At a glance

Climate change, together with other natural and human-made health stressors, can affect human health. Tracking Program data can be used to inform decision-making and policies that can help communities deal with a changing climate.

We Track That

While all communities are vulnerable to health effects associated with climate change, not everyone is equally at risk. Important considerations include age, economic resources, and location.

Data on the Tracking Network can improve understanding of how changes in temperature and precipitation influence human health. These data can inform decision-making and policies to help communities assess vulnerabilities, estimate burden, and build overall resilience against climate change.

Types of Data

Tracking partnered with CDC's Climate & Health Program to develop the Heat & Health Tracker. This interactive data dashboard puts local heat information into the hands of decision makers, media, and the public for every county in the United States.
