About the ROE

EPA's Report on the Environment (ROE) presents the best available indicators of national trends in the environment and human health. EPA selected these indicators to address 24 questions that are critical to EPA's mission of protecting the environment and human health. These questions are organized into six themes: Air, Water, Land, Human Exposure and Health, Ecological Condition, and Sustainability.

The ROE indicators serve as a tool for EPA decision-makers, program planners, scientists, researchers, the public, and others interested in environmental science and policy to track changes in environmental condition. They allow EPA and the public to assess whether the Agency is succeeding in its mission, and they help alert EPA to new challenges that may need attention and action.

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.
