Dr. Ben Poulter is a Research Scientist in the Biospheric Sciences Laboratory at NASA Goddard Space Flight Center. I use ecosystem models to better understand how climate change and elevated atmospheric CO2 will affect terrestrial carbon cycle stocks and fluxes. Remote sensing data, ground-based observations and experiments play a key role in developing and evaluating ecosystem models, and thus a range of interdisciplinary approaches are used in my research. I was recently a Contributing Author of Working Groups I and III of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change providing information on contemporary terrestrial CO2 and CH4 fluxes from land cover change and wetlands, respectively.
