- Abstract
The article presents a study that examines the net emissions of methane (CH4) in Alaska's ecosystem and atmosphere, and its contributions to carbon balance and greenhouse gas budget for the region. Under the investigation, (CH4) fluxes the 20th century to the 21st century were analyzed using the Terrestrial Ecosystem Model (TEM), a biogeochemistry model. A concept of global warming potentials was then used to convert net (CH4) emissions into carbon dioxide (CO2) equivalent units in terms of global warming effects. Results suggest that net methane emissions in the region will double by the end of the 21st century due to high-latitude warming and climate change, and that Alaska will be a net source of greenhouse gases to the atmosphere.
