    Particles Carry Toxic Pollutants Far from Home

    Combining state-of-the-art atmospheric modeling with the latest measurements-based findings, researchers at PNNL found that toxic particles can last longer and travel much farther than previous models predicted. The new insights indicate an estimate of global lung cancer risk from these pollutants four times higher than previously thought.

    Climate, Irrigation, and Fertilization: Understanding US Crop Yields

    Using corn and soybeans as their testing ground, researchers at PNNL devised methods to peer into the mechanisms that modulate crop yield variability. They used statistical models to examine how climate variability impacts yields of these popular bioenergy crops at the county level. The work showed that dynamically determining fertilization timing and rates in their models can greatly improve the predictive capability for yields of both crops.

    Less Salty Ocean is Right Up Typhoons' Alley

    Typhoon Alley, an area of the western tropical Pacific, already has destructive storms that rip through the region. That area may see more and more intense storms, according to researchers at PNNL. Their analysis of the strongest tropical storms over the last half-century— known as super typhoons— reveals that they are intensifying. Rain that falls on the ocean reduces its salinity and allows typhoons to grow stronger.

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.
