Climate Change Science

We are seeing the direct impacts of climate change today. Temperatures are rising, snow and rainfall patterns are shifting, and we are experiencing more extreme climate events – like heavy rainstorms and record-high temperatures. The U.S. Environmental Protection Agency (EPA) compiles a key set of indicators related to the causes and effects of climate change based on data contributions from more than 50 contributors ranging from government agencies, academic institutions and other organizations. Learn more about Climate Change Indicators and download the Indicators Factsheet (PDF).

The Intergovernmental Panel on Climate Change (IPCC) is an international body established by the United Nations to provide policymakers with regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation. Thousands of scientists from all over the world contribute to the work of the IPCC. Review is an essential part of the IPCC process, to ensure an objective and complete assessment of current information.

If you’d like to take a deeper dive and explore analyses by the world’s leading climate scientists, the best source of information is the IPCC, particularly its most recent Special Report: Global Warming of 1.5° C (PDF) analyzing the impacts of global warming of 1.5°C above pre-industrial levels. We recommend viewing The Smithsonian's Climate Change 101 with Bill Nye the Science Guy.
