New Roles at ARM Climate Research Facility Reflect Organizational Changes

The Climate Change Science Institute's Giri Palanisamy, along with his Pacific Northwest National Laboratory colleague Jennifer Comstock, have undertaken new professional roles within the ARM Climate Research Facility. Palanisamy's new role as ARM Architecture and Services Strategy Team (ASST) manager allows him to facilitate teamwork to craft a comprehensive, multi-year plan for ARM's computational environment.

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.


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.

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.
