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.

Dr. L. Ruby Leung, an internationally renowned atmospheric scientist specializing in climate modeling and the water cycle at Pacific Northwest National Laboratory, has been selected by the U.S. Department of Energy to lead the Accelerated Climate Modeling for Energy (ACME) project as Chief Climate Scientist. In this role, Leung will help guide the science behind one of...
Distinguished Climate and Earth System Modeling colleagues, Chris Bretherton, Phil Rasch, Alex Guenther, Bette Otto-Bliesner, and Ping Yang, are among the 60 American Geophysical Union (AGU) Fellows elected for 2015. The new Fellows were honored during the 2015 AGU Fall Meeting in San Francisco, Wednesday, December 16, 2015. Bretherton of University of Washington, Rasch...
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...

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.
