JGCRI is known for its research, modeling and integrated analyses at the interface of human, energy, and environmental systems. JGCRI is a global leader in the interdisciplinary field of integrated assessment of global change. The Global Change Assessment Model (GCAM), at the core of JGCRI’s integrated capabilities, is a global integrated assessment model that includes both comprehensive and detailed representation of human systems that drive or are affected by global environmental change. JGCRI research results are used widely in reports of the Intergovernmental Panel on Climate Change, the U.S. Global Change Research Program, U.S. Federal agencies, and leading think-tanks, private sector firms, and non-governmental organizations. Internships and fellowships at JGCRI provide training and research opportunities for a new generation of scientists.
