The article discusses how a scientific program, which was part of the 2007 International Polar Year, helped to advance the study by a group of researchers. Topics include how the extension of the program benefited methane emissions research by Torben Christensen and his colleagues on the Greenland tundra, an explanation of the International Polar Year, and a description of methane, which is a greenhouse gas, and its effects on the environment.
