Climate Change Indicators in the United States

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.

The information on this website is drawn from the second edition of EPA's Climate Change Indicators in the United States (PDF) (84 pp, 18.2MB), published in 2012. This report presents 26 indicators, each describing trends related to the causes and effects of climate change. It focuses primarily on the United States, but in some cases global trends are presented to provide context or a basis for comparison. The online version will be updated periodically as new data become available, and thus may differ from the printed version available below. You can find all the latest indicators using the tabs at the top of this Web page.
