Free Print Versions of EPA's Climate Change Indicators in the United States 2012 Now Available

The Earth’s climate is changing. Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events—such as heavy rainstorms and record high temperatures—are taking place. These types of changes can bring about fundamental disruptions in ecosystems, affecting plant and animal populations, communities, and biodiversity. Such shifts can also affect society, including where people can live, what kinds of crops farmers can grow, and what kinds of businesses can thrive in certain areas.

The U.S. Environmental Protection Agency’s Climate Change Indicators in the United States, 2012 report presents a set of 26 indicators tracking observed signs of climate change in the United States. EPA has worked in partnership with other agencies, organizations, and individuals to collect and communicate useful data about five categories of climate indicators: greenhouse gases, weather and climate, oceans, snow and ice, and society and ecosystems.

The report, Climate Change Indicators in the United States, 2012 is designed to be useful for scientists, analysts, decision-makers, educators, and others who can use climate change indicators as a tool for:

  • Assessing trends in environmental quality, factors that influence the environment, and effects on ecosystems and society.
  • Effectively supporting science-based decision making and communication.
  • Evaluating existing and future climate-related policies and programs.
