In the 1980s, the U.S. Geological Survey began a more systematic study of the remaining glaciers, which continues to the present day. By 2005, only 27 glaciers remained, and scientists generally agree that if the current greenhouse warming continues, all the glaciers in the park will be gone by 2030.[19] This glacier retreat follows a worldwide pattern that has accelerated even more since 1980. The extensive glacier retreat that has been observed in Glacier National Park, as well as in other regions worldwide, is a key indicator of climatic changes on a worldwide scale. Without a major climatic change in which cooler and moister weather returns and persists, the mass balance (accumulation rate versus melting rate) of glaciers will continue to be negative and the glaciers will eventually disappear, leaving behind only barren rock.[19]
