CLIMATE AND EARTH SYSTEM MODELING is part of the U.S. Department of Energy’s Office of Biological and Environmental Research (BER) Climate and Environmental Sciences Division (CESD). Our focus is on the development, evaluation, and use of regional and global climate models, development of Earth system models, and development of integrated assessment models to determine the impacts and possible mitigation of climate change.

for your DOE-funded modeling research


On February 5, the U.S. Department of Energy’s Office of Biological and Environmental Research (BER) opened a new DOE national laboratory announcement and a companion funding opportunity announcement (FOA) for the Climate Model Development and Validation (CMDV) activity. The CMDV activity is a new effort to improve climate model architecture, software, and computational...

Program Information

Earth System Modeling

Earth System Modeling (ESM) concentrates on advancing coupled climate and Earth system models for climate change projections at global-to-regional spatial scales and temporal scales spanning decadal to centennial.

Regional & Global Climate Modeling

Regional & Global Climate Modeling (RGCM) advances the predictive understanding of Earth’s climate by focusing on scientific analysis of the dominant sets of governing processes that describe climate change on regional scales.

Integrated Assessment Research

Integrated Assessment Models guide understanding of global climate change by addressing its drivers, pace, consequences, and implications. They inform some of the most significant energy, economic, and infrastructure decisions affecting the world today.
