       Advancing the knowledge of climate change and understanding its consequences


ORNL researchers enhance access to US government climate-data resources

The latest addition to, “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.

ORNL-led team spearheads approach to improve ecosystem models with experimental data

Predicting how forests will respond to increased levels of atmospheric carbon dioxide involves understanding the interplay among carbon dioxide, nutrients, water, plant and soil processes.

Oak Ridge National Laboratory ecologist Rich Norby has spent his career pondering these fundamental questions, including more than a decade studying the effe

ACME continues to soar with yet another award

Bill Collins, Lawrence Berkeley National Laboratory; Mark Taylor, Sandia National Laboratory; and David Bader, Lawrence Livermore National Laboratory were co-recipients of the DOE Secretarial Honor Award for their leadership of the Accelerated Climate Modeling for Energy (ACME) project. Secretarial Honor Awards, the department’s highest form of nonmonetary employee recognition, are awarded to individuals and teams selected by the Secretary of Energy for significant achievements on behalf of the department and for the benefit of the nation.

Launched in 2014, ACME is a multi-laboratory initiative to harness the power of supercomputers like ORNL’s Titan and Argonne’s Mira to develop fully coupled state-of-the-science Earth system models for climate change research and scientific and energy applications. Eight national labs, the National Center for Atmospheric Research, four academic institutions, and one private sector company are collaborating on the 10-year project. Researchers from ORNL’s Climate Change Science Institute (CCSI) were instrumental in developing and defending the project plan and are leading or coleading several project teams, including the teams responsible for new land model development (Peter Thornton), assessing and improving model performance on high-performance computing platforms (Patrick Worley), and developing and evaluating simulation workflow tools (Kate Evans).

CCSI’s Peter Thornton, who serves on the ACME governing council with Collins, Taylor, and Bader, had this to say: “We’re very happy that the ACME Executive Committee has received this honor. The award citation highlights the fact that ACME is bringing DOE’s climate research community together ‘under one roof.’ It is exciting to be a part of that collective effort, and it’s rewarding to know that this kind of broad collaboration is valued at the top of the agency.”

This is not the first time in ACME’s short history that an ACME team has received a national award. In April CCSI and National Center for Computational Sciences members were part of the Ultra-Scale Visualization Climate Data Analysis Tools (UV-CDAT) project team awarded the prestigious Federal Laboratory Consortium Interagency Partnership Award. UV-CDAT is ACME’s visualization-diagnostic-analytical component.

The awards were presented by Secretary Moniz during a special program held May 8 at DOE headquarters in Washington, DC.

CCSI Staff Member Participates in First UT Women in STEM Research Symposium

The Climate Change Science Institute’s (CCSI’s) Colleen Iversen was invited to participate in the First Annual University of Tennessee Women in STEM Research Symposium, April 18, 2015.

CCSI intern earns 2015 UT-Battelle Scholarship

High school senior Samuel Feldman of Hardin Valley Academy in Knoxville has earned the 2015 UT-Battelle Scholarship to attend the University of Tennessee.

The scholarship, given to a graduating senior planning to study a science field at UT, is renewable for four years and is worth a total of $20,000. The scholarship is awarded annually to a student who has a parent who works at ORNL.

Samuel's parents are Matthew and Laura Feldman of Knoxville. His father, Matthew, works in ORNL's Reactor and Nuclear Systems Division. Sam's grandparents are Mary and Jim Luttrell and Nancy and the late Melvin Feldman, who retired from ORNL.

Before his senior year, Samuel accepted an internship in ORNL's Climate Change Science Institute. Though he finds research stimulating, he also thinks that being able to communicate complex science to policy makers and the public is important. At UT he plans to further his studies in climate change science by choosing a field that mixes both.

In addition to being an ORNL summer intern, Samuel is a member of the Technology Student Association and has served as the local chapter's president and two terms has a Tennessee TSA State officer. He's also part of the HVA FIRST robotics team and HVA ultimate Frisbee team.

His other accolades include a 2015 National Merit Finalist, 2nd place in the 2015 Department of Energy Tennessee Science Bowl and 3rd place in its 2014 competition. He is part of the National Honor Society and an AP Scholar with Distinction. Samuel also received a National Merit Corporate Scholarship from Battelle. This award is $1000 per academic school year.
