The Earth’s climate is changing. Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events—like heavy rainstorms and record high temperatures—are already taking place. Scientists are highly confident that many of these observed changes can be linked to the climbing levels of carbon dioxide and other greenhouse gases in our atmosphere, which are caused by human activities.

EPA partners with over 40 data contributors from various government agencies, academic institutions, and other organizations to compile and communicate key indicators related to the causes and effects of climate change. The 30 indicators presented here are published in EPA’s Climate Change Indicators in the United States report.

Explore this website or download the latest report to learn more about the changes we are seeing now. Indicators are updated periodically on the Web as newer data become available. For additional information about EPA’s climate change indicators, see Frequent Questions.
