    The Surprising Clarity of Dust

    PNNL researchers, working with collaborators, found that desert dust actually promotes winds over China to whisk away human-caused pollution. When the dust is absent, the air doesn't move, allowing pollution to build up and linger in the atmosphere. Especially during the winter, reduced dust levels led to a 13 percent increase in human-caused pollution over eastern China.

    Edmonds to Join Rutgers Energy Institute Advisory Board

    James "Jae" Edmonds accepted an invitation to join the Rutgers Energy Institute Advisory Board. Edmonds is a Laboratory Fellow and senior scientist at the PNNL's Joint Global Change Research Institute, a partnership with the University of Maryland in College Park.

  • Teleconnections

    Teleconnections in Climate Models

    Researchers from PNNL, working with a colleague at Cornell University, borrowed a technique from engineering to efficiently discover distant input-output relationships in climate models. The new technique shows promise by zeroing in on teleconnections in ways that other modeling methods have not.

  • Soot sources

    Sources of Soot over China

    Scientists at PNNL developed a unique computational tagging technique to detect the influence of local vs. non-local sources of soot on China's regional air quality. They used this technique to determine how much each soot source—local or remote—contributed to atmospheric warming over China. An effective program to reduce soot impacts in a particular region requires knowing the source of the soot—whether it is from within the region, or imported from another area.

    International Path to Efficient New Buildings

    PNNL researchers took a systematic approach to synthesize building energy code implementation systems in 22 countries finding a guide to successful and best practices for achieving energy-efficient buildings. They found that robust enactment of those codes typically involves many essential and interconnected elements.

How do human activities and natural systems interact to affect the Earth's climate? Ultimately, that is the question challenging scientists in PNNL’s Atmospheric Sciences & Global Change Division.
