Getting to know our early career scientists: Jiafu Mao

CCSI scientist Jiafu Mao, of the Terrestrial Systems Modeling group in the Environmental Sciences Division, parlayed his interest in physics and mathematics as a student in China into a field of study he has always found interesting: how land and climate interact.

ORNL Contributes to Second SECURE Water Act Report to Congress

Scientists within ORNL’s Energy-Water Resource Systems team and Climate Chance Science Institute provided key data to the 2017 DOE SECURE Water Act Section 9505 Report to Congress. The findings indicate a need to allocate water use more cautiously in response to the trend of earlier snowmelt and change in runoff seasonality. ORNL researchers provided metrics on historic hydrologic observations and hydropower facility characteristics to support model development, calibration, and verification. The 9505 Assessment Report will be used to help policy makers evaluate potential climate change effects across the United States’ hydropower fleet.

Tidal Wetland Ecosystem Process Modeler Postdoctoral Fellow

Seeking a postdoctoral researcher to join an interdisciplinary team on an exciting new manipulative experiment that examines the interactions of warming, elevated CO2, and inundation frequency in coastal wetland marsh ecosystems. The position focuses on the development, application, and analysis of new computational models that couple energy, water, carbon, and nutrient dynamics in tidal wetland systems. This successful candidate will collaborate with an active modeling team and be expected to interact closely with other research groups working on field experiments and observations. 

Warming global temperatures may not affect carbon stored deep in northern peatlands

Deep stores of carbon in northern peatlands may remain stable despite rising temperatures, according to a team of researchers from several U.S.-based institutions. And that is good news for now, the researchers said.

Global Carbon Budget: Fossil fuel CO2 emissions growth nearly flat; atmospheric concentration continues to rise

The latest annual Global Carbon Budget shows the growth of carbon dioxide (CO2) emissions from fossil fuel use is likely to be nearly flat for the third year in a row, with fewer emissions from coal burning a possible factor. Even with that slowdown, however, atmospheric CO2 continues to climb—growing by a record high of 23 gigatonnes (Gt) in 2015 and projected to grow 25 Gt in 2016.
