Climate Change Indicators in the United States
The information on this website is drawn from the third edition of EPA's Climate Change Indicators in the United States (PDF) (112 pp, 24.1MB), published in 2014. This report presents 30 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 is 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.

In March 2011, EPA’s Climate Change Division (CCD) organized a workshop with experts on various aspects of climate change. The workshop was intended to gather feedback on EPA’s 2010 report, Climate Change Indicators in the United States, and to gather suggestions for future versions of the report and its content. The workshop report (PDF) (22 pp, 235K) summarizes participant feedback and key discussions.
