Our researchers are transforming the nation's ability to predict climate change and its impacts. Combining a global field observational system with advanced modeling and laboratory research, PNNL scientists improve scientific understanding of how atmospheric processes and energy technology choices affect greenhouse gas emissions and their consequences. The result: new insights that help leaders manage risks and cope with climate impacts while meeting society's energy demands.
Terrestrial CO2 Economically Important in Greenhouse Gas Control
According to a study by the Joint Global Change Research Institute, failing to include land use changes in policies to stabilize greenhouse gases in the atmosphere could lead to massive deforestation and higher costs for limiting carbon emissions.» More

Thawing the Mystery of Extra Ice Crystals
A team led by Pacific Northwest National Laboratory (PNNL) researchers has presented two processes, or explanations, for how extra ice crystals form in mixed-phase clouds—clouds containing both water and ice—which are prevalent throughout the Arctic.» More
Clouding the Issue
Over time scales spanning at least a decade, the amount of sunlight that reaches the Earth's surface has varied. These variations affect the total amount of incoming and outgoing energy in the Earth system, which, in turn, affects climate change. Scientists refer to these variations as global dimming and brightening.» More
Beat Schmid Receives Dual Honor from DOE Office of Science
Congratulations to Dr. Beat Schmid of Pacific Northwest National Laboratory who recently was honored with two awards by the U.S. Department of Energy Office of Science. These two awards recognize Beat's leadership contributions to the Atmospheric Radiation Measurement (ARM) Program, a DOE multi-laboratory, interagency program for global climate change research. The awards honored Beat's three-year terms as a member of the ARM Climate Research Facility Science Board and as leader of the ARM Program's Aerosol Working Group.» More
