Keith Paustian is University Distinguished Professor in the Department of Soil and Crop Sciences and Senior Research Scientist at the Natural Resource Ecology Laboratory at Colorado State University.  A major focus of his work involves modeling, field measurement and development of assessment tools for soil carbon sequestration and greenhouse gas emissions from soils. He has published over 250 journal articles and book chapters. Previous and current research activities include development models and inventory methodology used to estimate US soil C and N2O emissions that are reported annually by EPA to the UNFCCC; development of a web-based tool (COMET-FarmTM) for estimating on-farm greenhouse gas (GHG) emissions and carbon sequestration used by USDA ( and project-scale systems for GHG assessment of sustainable land management projects in developing countries (  He also serves as project director for the Bioenergy Alliance Network of the Rockies (BANR –, a consortium of universities, industry and government, researching the potential for sustainable bioenergy production from beetle-kill trees and forest residues. Professional service activities include Coordinating Lead Author for the IPCC 2006 National Greenhouse Gas Inventory Methods and the IPCC 2003 Good Practice Guidance for LULUCF, a 2010 National Academy of Science panel evaluating greenhouse gas measurement methods and verification issues, and member of the US Carbon Cycle Science Steering Group, which provides expert input to Federal Agencies involved in climate and carbon cycle research.  He also served on the Voluntary Carbon Standard Steering Committee for Agriculture, Forestry and Other Land Use (AFOLU) and on numerous other national and international committees involving climate and carbon cycle research.  He is a Fellow of the Soil Science Society of America and 2015 recipient of the Soil Science Society of America’s Outstanding Research Award.

Dr. Kevin Schaefer

National Snow and Ice Data Center,
University of Colorado, USA

Topic : ” The Interaction between Arctic Permafrost and Global Climate “

Dr. Schaefer studies both the impact of climate change on permafrost and the impacts of thawing permafrost on global climate.  Dr. Schaefer received a degree in aerospace engineering from the University of Illinois in 1984.  He worked for the National Aeronautics and Space Administration supporting Space Shuttle operations, serving as a program manager during the design of the Space Station, and developing data systems for Earth Science data.  He supported the White House Council of Environmental Quality developing indicators of sustainable development before returning to school in 1997.  Dr. Schaefer graduated with a PhD in atmospheric Science from Colorado State University in 2004 and served as a postdoc monitoring atmospheric CO2 at the National Oceanic and Atmospheric Administration, before settling at the National Snow and Ice Data Center at the University of Colorado in Boulder as a research scientist.  Dr. Schaefer currently focuses on teaching, modeling of the terrestrial carbon cycle in permafrost, and remote sensing of permafrost dynamics using radar.
