    Richard Moss to Guide Next Phase of US National Climate Assessment

    Richard H. Moss, a scientist working at PNNL's Joint Global Change Research Institute in College Park, Maryland, was appointed to chair the 15-member Advisory Committee for the US Sustained National Climate Assessment. The appointment was announced by the National Oceanic and Atmospheric Administration on June 29th.

    Digging into Clouds from the Bottom Up

    Scientists at PNNL got creative with the data they already have to calculate a cloud property normally acquired by research aircraft flying through it. What is this valuable measurement they seek? The cloud droplet number concentration provides insight into how reflective and long-lasting a cloud is, to understand the amount of sunlight energy that hits Earth's surface.

    Richard Moss Appointed a National Research Council Associate

    Richard H. Moss, a scientist working at PNNL, was recently appointed a National Associate of the National Research Council, the operating arm of the National Academies of Sciences, Engineering and Medicine. The National Academies reserve the associate designation for those with extraordinary service in performing pro bono publico for the NRC. Out of the thousands of dedicated and eminent individuals, Moss is one of a small number chosen for this distinct honor in 2016.

    Future Water Scarcity: Assessments from a Global View

    PNNL research conducted at the Joint Global Change Research Institute developed a unique modeling capability to understand how global water supplies and demands might interact over the rest of the century under different assumptions about the future. The modeling capability employed provides a way to understand the impact of climate change on water availability and the implications of water scarcity on agriculture and energy.

    Little Big Parameter

    PNNL scientists developed a new method to represent how local wind speeds can lift natural aerosol particles into the atmosphere. The technique proved to be computationally efficient, making the approach more feasible to adopt. When researchers considered these effects in a global climate model, they found two surprising results. In some cases, the amount of dust produced a year (yearly mean) increased by more than 50 percent. In others, the mean remained the same, but the amount of dust raised by weaker winds was higher.

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.
