Climate Change Indicators in the U.S.

Weather and Climate text with Sun and Clouds

EPA has released the most recent edition of Climate Change Indicators in the United States, which includes several new indicators on climate and health.

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 happening. Many of these observed changes are linked to the rising levels of carbon dioxide and other greenhouse gases in our atmosphere, caused by human activities.

EPA partners with more than 40 data contributors from various government agencies, academic institutions, and other organizations to compile a key set of indicators related to the causes and effects of climate change.

Major topics and issues cover: Greenhouse Gases (U.S. and global greenhouse gas emissions), Weather and Climate (U.S. and global temperatures, precipitation, drought), Oceans (Ocean heat, sea surface temperature, sea level, ocean acidity, coastal flooding), Snow and Ice (snow cover, snowpack, glaciers, snowfall), Health and Society (heat-related illnesses and deaths, growing season, ragweed pollen season, Lyme Disease), and Ecosystems (wildfires, stream flow, stream temperature, bird wintering ranges, marine species, leaf and bloom dates). All general topics have a summary.  

This resource also features more specific climate-related research, such as climate change and human health, temperature and drought in the southwest, land loss along the Atlantic coast, ice breakup in Alaskan rivers, cherry blossom bloom in Washington D.C., and stream temperature in the Snake River.
