Homeland Security awards ORNL team for highlighting climate change risks to vulnerable Maine bay

Members of Oak Ridge National Laboratory’s (ORNL’s) Climate Change Science and Urban Dynamics Institutes, in collaboration with team members from the US Department of Homeland Security (DHS) and other US Department of Energy national laboratories, have been awarded the DHS Office of Infrastructure Protection’s Trailblazer Award for their contributions to a DHS project known as the Regional Resiliency Assessment Program (RRAP).

ORNL forest threat warning system in White House’s “top 25” climate resilience tools

ForWarn, the early warning system for forest threats developed by Oak Ridge National Laboratory (ORNL) and Climate Change Science Institute researchers and collaborators, has been included in the US Climate Resilience Toolkit’s “top 25” tools.

ORNL’s James Hack elected Fellow of American Meteorological Society

James Hack, director of the National Center for Computational Sciences at the Department of Energy’s Oak Ridge National Laboratory (ORNL), has been elected a 2015 Fellow by the American Meteorological Society (AMS). Hack, also founding director of ORNL’s Climate Change Science Institute, was cited for his “outstanding contributions to advancing the atmospheric and related sciences, technologies, applications and services for the benefit of societ

Subsurface science expert Scott Painter joins CCSI staff from LANL

The Climate Change Science Institute (CCSI) at Oak Ridge National Laboratory (ORNL) welcomes subsurface flow and reactive transport modeler Scott Painter. Scott is joining multiple ORNL projects, including the Next-Generation Ecosystem Experiments (NGEE)–Arctic and NGEE–Tropics. He will also lead one of the use cases for the new Interoperable Design of Extreme-scale Application Software (IDEAS) project, which he helped develop.

Giri Palanisamy named new ARM Data Service and Operations Manager

Giri Palanisamy, a scientist with the Atmospheric Radiation Measurement (ARM) Archive and the Climate Change Science Institute, has been named the ARM Data Service and Operations manager. In this position, Giri will be responsible for the leadership and management of the Archive, Data Management Facility, External Data Center, and Site Data Systems.

Climate scientists put multiple models to the test

Researchers with Oak Ridge National Laboratory’s (ORNL’s) Climate Change Science Institute (CCSI) are part of a multipartner team that is evaluating how the structures of terrestrial biosphere models (TBMs) influence the results of model simulations.

CCSI collaborator wins Australian Climate Adaptation Champions award

Australian governments on the local to national level are preparing for increased erosion, storm damage, and sea-level rise along the country's coastlines as a changing climate poses new risks.

Jim Hack invited Smithsonian Grand Challenge Consortia speaker

National Center for Computational Science Director Jim Hack is among the speakers invited to the Smithsonian Institution's 2014 Grand Challenges Consortia. Similar to the 2012 conference, this year's meeting will focus on the Anthropocenene, the informal name given to the current period of geologic time in which many scientists consider humans a major driver in climatic and environmental change on Earth.
