    PNNL scientist contributes to global analysis of effects of rising temperatures

    A new study predicts that warming temperatures will contribute to the release into the atmosphere of carbon that has long been locked up securely in the coldest reaches of our planet. Scientists from more than 30 institutions across the globe, including PNNL, collaborated on the study.

    Changing the Game

    This year alone, Shuaiwen Leon Song, a research scientist with PNNL’s High Performance Computing group, has co-authored several papers that have been accepted at major, highly competitive HPC-related international conferences. He recently added to that tally with two more papers that will be featured at upcoming conferences that focus on diverse and leading-edge research related to high-performance computer architectures.

    Roger Rousseau Honored for Exceptional Scientific Achievement

    Congratulations to Roger Rousseau on receiving the Exceptional Scientific Achievement Award from Pacific Northwest National Laboratory. A force for collaboration and computational chemistry, Rousseau advances and integrates computational chemistry to improve vital technological processes. These processes include capturing carbon dioxide, catalytically turning that carbon into fuels, and producing biofuels.

    Getting at the Root of Rain

    Researchers at PNNL studied the last 35 years of weather and showed that large intense storms are now more frequent and long-lasting, even as lighter rain storms have decreased. The source, they found, is changing climate in the Southern Great Plains states in contrast with the proximity of the ocean that produces winds carrying moisture from the Gulf of Mexico to the Great Plains.

Our researchers advance the frontiers of science to study, predict, and engineer complex adaptive systems related to Earth, energy, and security. Our investigations inhabit every scale. We study the vast whirl of aerosol-laden clouds; the complex shoreline interfaces of land and sea; the mysterious microbiomes that teem just beneath the Earth’s surface; and the myriad of molecules busy on surfaces just angstroms wide.

We investigate elemental chemical and physical processes, including new catalysts that speed up the efficiency of renewable fuels. We study climate system dynamics to predict the effects of climate change. We design and synthesize the functional and structural materials of the future, including robust metal foils thinner than a human hair.

We are proud to host two unique DOE user facilities. EMSL facilitates molecular-level investigations into the physical, chemical, and biological processes that underlie the Earth’s most critical environmental issues. ARM provides a setting for climate research and instrumentation development, and is strengthened by streaming data from a worldwide complex of sensing stations.
