New research reveals the extent of the glacial retreat in the national park named for glaciers.
"Glacier National Park is losing its namesake glaciers and new research shows just how quickly," writes Andrea Thompson. "Over the past 50 years, 39 of the parks glaciers have shrunk dramatically, some by as much as 85 percent."
All told, only 26 of the 150 glaciers that existed in the park during the 19th century remain, according to a study by U.S. Geological Survey researchers that provide the evidence for the article.
With the retreat of park's glaciers in full effect, it's possible that the lack of glaciers could greatly reduce demand for tourism to the park. Much more sure, however, is the potential impact on local ecosystems that depend on seasonal releases of glacial meltwater. "Summer meltwater helps top up streams that might otherwise run dry and many species are highly adapted to the cold temperatures of the water," explains Thompson.
