The Global Change Information System (GCIS); a product of the U.S. Global Change Research Program (USGCRP); is an open-source, web-based resource designed for use by scientists, decision makers, and the public. As a centralized catalog of all materials and data used for USGCRP products and climate assessments; the system acts as an advanced, multifaceted bibliography, maintaining traceable provenance records of scientific information and providing access to the original data and research. The GCIS documents the cross-links among research papers, researchers, original data, and more and includes links back to authoritative sources for its information. In addition, the GCIS guides users to global change research produced by the 14 USGCRP member agencies.
