Drying Arctic soils could accelerate greenhouse gas emissions

OAK RIDGE, Tenn., June 13, 2016—A new study published in Nature Climate Change indicates soil moisture levels will determine how much carbon is released to the atmosphere as rising temperatures thaw Arctic lands. An international team led by Northern Arizona University scientists analyzed the results of 25 experiments from multiple research groups including the Department of Energy’s Oak Ridge National Laboratory. The researchers had measured the release of greenhouse gases from incubated soil samples, which originated in field sites in Alaska, Canada and Russia, under a temperature increase of 10 degrees Celsius.

Senior Research Scientist Positions Available at CCSI

The Climate Change Science Institute (CCSI) at Oak Ridge National Laboratory (ORNL) is recruiting two senior research scientists. One position is in the Impacts, Adaptation, and Vulnerability (IAV) group and the other is for a data scientist in the Data Integration, Dissemination, and Informatics (DIDI) group.

CCSI’s Melanie Mayes receives DOE SC Early Career Research Program award

Melanie A. Mayes

The Climate Change Science Institute’s (CCSI’s) Melanie Mayes was one of four ORNL researchers to receive a 2016 US Department of Energy (DOE) Office of Science (SC) Early Career Research Program research grant. The program, now in its seventh year, is designed to bolster the nation's scientific workforce by providing support to exceptional researchers during the crucial early career years, when many scientists do their most formative work.

ACME—scaling the heights of Earth system modeling

The Accelerated Climate Modeling for Energy (ACME) project, now in its second year, has already racked up numerous awards, most recently “best video” at Supercomputing 2015 in Austin, Texas. More important, the team, which consists of eight national laboratories, the National Center for Atmospheric Research, four academic institutions, and one private-sector company, is on schedule for release of Version 1 of the ACME model in June 2016.

CCSI’s Devarakonda named IEEE Senior Member

The Oak Ridge National Laboratory (ORNL) Climate Change Science Institute’s (CCSI’s) Ranjeet Devarakonda has been elevated to the grade of IEEE Senior Member. Senior Member is the highest grade for which members of the Institute of Electrical and Electronics Engineers (IEEE) can apply and requires at least 10 years professional experience and 5 years of significant achievements.
