AB: While climate warming is suggested to have caused acceleration of Greenland Ice Sheet outlet glaciers, recent warming, however, is not without precedent. Examination of Greenland's meteorological stations confirms that 1920s through 1940s surface-air temperature anomalies were at least as equal in magnitude to the recent "global warming" decade, yet observations have not yet been compiled to confirm a similar glacier response. Mining The Ohio State University Libraries, this work compiles historical observations of glacier front positions and surface velocities from maps, photographs and other documentary evidence from mid 19th century Arctic expeditions. Of the glaciers reviewed, an acceleration and retreat indeed occurred between 1920 and 1940. The research put forth is thus consistent with a dynamical response in Greenland's outlet glaciers to the "roaring twenties" warming.
