Climate Change Adaptation Resource Center (ARC-X)

Implications of Climate Change

There are many resources available that describe the implications of climate change. Some present information on historically observed changes (e.g., temperature, precipitation) while others project changes into the future based on alternative scenarios (e.g. frequency of intense storms in the future). U.S. National Climate Assessment synthesizes the best available scientific information. 

This resource center focuses on helping communities adapt to the changes as documented in the U.S. National Climate Assessment (2018). The ARC-X has a particular focus on climate impacts related to EPA's statutory responsibilities, as the Agency works to fulfill its mission of protecting human health and the environment.

For those interested in learning more about the implications of climate change, links to resources are provided below.

U.S. National Climate Assessment NCA

Since 1990, the U.S. Global Change Research Program (USGCRP) has helped the Nation to understand, assess, predict, and respond to human-induced and natural processes of global change. USGCRP issued its fourth, and most recent National Climate Assessment (NCA4) in 2018. The NCA serves as the foundation of the scientific information reflected in the Adaptation Resource Center.
