Mapping potential carbon emissions from thawing permafrost

A new global mapping project has for the first time assessed thermokarst landscapes in the northern circumpolar region, concluding that as much as half of the carbon below-ground and at risk of being released into the atmosphere lies in these unique landforms. Thermokarst forms when ice-rich permafrost ground thaws and causes land subsidence. The mapping project, led by the University of Alberta and the Climate Change Science Institute (CCSI) at Oak Ridge National Laboratory, estimates that these landforms cover about 20% of the northern permafrost.

Water security in a warming climate

Californians are currently struggling with what one source has referred to as the worst drought in more than 1,200 years, and this may be only the beginning. Increases in the frequency and intensity of floods and droughts may pose potentially severe challenges to water supply throughout the southwestern United States by mid-century. That is the verdict of a new study by researchers at Loyola Marymount University (LMU) and the Climate Change Science Institute (CCSI) at Oak Ridge National Laboratory (ORNL).

ORNL DAAC MODIS Team recipient of NSDI Champion of the Year Award

The ORNL Distributed Active Archive Center for Biogeochemical Dynamics (DAAC) MODIS Team is the recipient of the first Doug D. Nebert NSDI Champion of the Year Award. The ORNL DAAC won this award for developing an innovative tool suite to allow users to access and use complex MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data sets easily. The visionary leadership shown by the ORNL DAAC MODIS Team and its members and their emphasis on service and dedication to National Spatial Data Infrastructure (NSDI) principles uniquely fit the team for this honor.

Omitaomu elevated to IEEE senior rank

Olufemi (Femi) Omitaomu of the Oak Ridge National Laboratory (ORNL) Climate Change Science and Urban Dynamics Institutes (CCSI and UDI) 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, including 5 years of significant achievements.

Bob Andres—lessons from an unplanned career

Bob Andres of the ORNL Climate Change Science Institute (CCSI) and Carbon Dioxide Information Analysis Center (CDIAC) has been a volcanologist, a geochemical consultant, a university professor, a laboratory manager, a remote sensing expert, and an instrument developer over the course of a 24-year career that has spanned numerous organizations, including two national laboratories, and taken him all over the world. “My career, or rather its trajectory, was certainly not planned,” Andres says.
