Retreat of Glaciers in Glacier National Park... In Glacier National Park (GNP), MT some effects of global climate change are strikingly clear. Glacier recession in underway, and many glaciers have already disappeared. The retreat of these small alpine glaciers reflects changes in recent climate as glaciers respond to altered temperature and precipitation. It has been estimated that there were approximately 150 glaciers present in1850, and most glaciers were still present in 1910 when the park was established. In 2010, we consider there to be only 25 glaciers larger than 25 acres remaining in GNP. A computer-based climate model predicts that some of the park’s largest glaciers will vanish by 2030 (Hall and Fagre, 2003). This is only one model prediction but, if true, then the park’s glaciers could disappear in the next several decades. However, glacier disappearance may occur even earlier, as many of the glaciers are retreating faster than their predicted rates.
