The Issue
The term global climate change refers to the average pattern of earth's weather over time. Scientific evidence increasingly indicates that the earth's climate is changing due to human activities. Global climate change has the potential to affect ecosystems, air and water quality, and human health.
EPA Action
EPA scientists are focused on evaluating the potential consequences of global climate change and providing policy makers with the scientific information they need to make informed decisions in the face of climate change.
Within EPA's National Center for Environmental Assessment, the Global Change Assessment Staff is working to provide scientific information and decision tools to resource managers, policy makers, and other stakeholders in order to support them as they decide whether and how to respond to global climate change. Their research is focus on the effects of global change on air quality, water quality, ecosystems, and human health.
Across ORD there are several other climate change programs including:
- NCER’s STAR program is working towards EPA’s research goal of understanding the possible consequences of global change on human health, ecosystems and social well-being,
- NERL's Atmospheric Sciences Modeling Division, who are looking at consequences of climate change for U.S. air quality Climate Impact on Regional Air Quality (CIRAQ), and
- NRMRL's Atmospheric Protection Branch who are working on global change and climate research.
- EPA Climate Change
- Climate Change and the Health of Children
- ORD's Global Change Research Program
- U.S. Climate Change Science Program (CCSP)
