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.

The Southern Ocean's clouds can cool the Earth by reflecting sunlight that would otherwise be absorbed by the darker ocean below. Phytoplankton help with that. Image courtesy of NASA.
How clouds form and how they help set the temperature of Earth are two of the big remaining questions in climate research. Now, a study of clouds over the world's remotest ocean shows that ocean life is responsible for up to half the cloud droplets that pop in and out of existence during summer. A team of scientists led by Pacific Northwest National Laboratory...
The Department of Energy (DOE) Office of Science Graduate Student Research (SCGSR) Program is accepting new applicants for supplemental funds to conduct part of their thesis research at a DOE laboratory in areas that address scientific challenges central to the Office of Science mission. These research opportunities are expected to advance graduate students'...
J. Keith Moore, University of California, Irvine
Marine biogeochemist and model developer J. Keith Moore received the 2015 Community Earth System Model (CESM) Distinguished Award at the 20th Annual CESM Workshop on June 15. Moore, Associate Professor of Earth System Science at the University of California, Irvine, was cited for more than 10 years of service to the Biogeochemistry Working Group and for his contributions...

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.
