Assessing Humanity's Impact on Global Climate

Lawrence Livermore's Atmospheric Sciences Division is applying computation expertise-originally developed to simulate nuclear explosions-to the task of climate modeling. We also make use of Livermore expertise in atmospheric science that grew out of efforts to model fallout from nuclear testing. These model-building and simulation efforts in climate studies are synergistic with other Laboratory programs that depend on combining computing with information and communication management.
Major efforts are aimed toward understanding how the biosphere and oceans take up and remove carbon dioxide, what role pollutants from fossil fuels play in determining sulfate aerosol concentrations and the impact on climate, and to what degree climate naturally varies within the biosphere. In addition, we work to reduce systematic errors in the models in collaboration with researchers in LLNL's Program for Climate Model Diagnosis and Intercomparison.
