DOE event marks beginning of landmark ecosystem experiment

GRAND RAPIDS, Minn. Aug. 26, 2015 – Scientists are getting a glimpse of the future with a Department of Energy large-scale experiment designed to answer questions about how carbon-rich peatlands will respond to projected warming of the climate and increases in atmospheric carbon dioxide.

CARBON NUMBER CRUNCHING

ORNL data experts aid new analysis of Chinese fossil-fuel carbon emissions

A booming economy and population led China to emerge in 2006 as the global leader in fossil-fuel carbon emissions, a distinction it still maintains. But exactly how much carbon China releases has been a topic of debate, with recent estimates varying by as much as 15 percent.

Melanie Mayes honored as YWCA Tribute to Women finalist

On September 17th, the Knoxville YWCA will hold its 31st Annual Tribute to Women celebration, and the ORNL Climate Change Science Institute’s (CCSI’s) Melanie Mayes is one of the finalists. The Tribute to Women is East Tennessee’s premier occasion for recognizing the accomplishments of women across the region.

Preston to receive 2015 American Geophysical Union Falkenberg Award

Dr. Benjamin L. Preston, senior research scientist and deputy director of the Oak Ridge National Laboratory (ORNL) Climate Change Science Institute, has been awarded the 2015 American Geophysical Union’s (AGU’s) Charles S. Falkenberg Award.

CCSI researchers extend use of Shared Socioeconomic Pathways for use at the subnational level

Using Shared Socioeconomic Pathways (SSPs) and the Factor-Actor-Sector framework, the Climate Change Science Institute’s Syeda Mariya Absar and Benjamin L. Preston have extended the SSPs to give climate scientists a new tool for use in impact, adaptation, and vulnerability studies at the subnational level.

ORNL researchers enhance access to US government climate-data resources

The latest addition to Data.gov, “home” of the US government’s open data, launched June 25, 2015, thanks to a team led by Benjamin Preston of the Climate Change Science Institute (CCSI) at Oak Ridge National Laboratory (ORNL).

Climate researchers’ article on coastal vulnerabilities a top read in new journal

When Megan Maloney, a post-bachelor’s researcher at Oak Ridge National Laboratory (ORNL), and Ben Preston, deputy director of ORNL’s Climate Change Science Institute, submitted an article on coastal vulnerability to a new journal, they were aware of the significance of their results.

NGEE Arctic: Science on the tundra requires rigorous safety planning

Just like any experiment that sends researchers into the field, project lead Stan Wullschleger prepares a scrupulous safety plan that encompasses the same safety culture and planning that are practiced with experiments close to home. Where his plan differs from others is that his list of potential hazards includes polar bears.
