What Is the ROE?
EPA's Report on the Environment (ROE) is an interactive resource that shows how the condition of the environment and human health in the United States is changing over time. Targeted for anyone interested in environmental trends, the ROE presents the best available indicators of national trends in five theme areas of interest to EPA: Air, Water, Land, Human Exposure and Health, and Ecological Condition. EPA selected the 85 ROE indicators to address 23 questions within these five theme areas that are critical to EPA's mission of protecting the environment and human health. The ROE is a dynamic resource. EPA updates the ROE indicators on a rolling basis to provide the latest available data and adds new indicators when relevant. Use the multi-colored navigation bar 
at the top of every ROE Web page to explore the ROE themes, the associated questions, and the indicators that help answer these questions.
Featured Indicator:
U.S. and Global Temperature
and Precipitation
The eight exhibits in this indicator show trends in temperature and precipitation in the U.S. and worldwide. EPA cares about these trends because they are fundamental to understanding changes in climate and their wide–ranging effects (e.g., sea–level rise) on human life and ecosystems. The exhibit above, which focuses on changes in temperature in the U.S., shows that:
- Overall, average temperatures in the U.S. have risen since 1901.
- Warming has occurred throughout most of the U.S., with temperatures in parts of the North, the West, and Alaska increasing the most.
