In this video adapted from KUAC-TV and the Geophysical Institute at the University of Alaska, Fairbanks, learn how one-celled organisms in permafrost may be contributing to greenhouse gas levels and global warming. Investigate how soil microbes, once thought to be dormant in cold temperatures, may actually be actively decomposing organic matter throughout the Alaskan winter and contributing significant amounts of carbon dioxide to the atmosphere. In addition, learn how microbial activity may be part of a positive feedback loop that also links shrub growth and warmer soil temperatures.
