ZitatThe National Park Service quietly removed a visitor center sign that claimed all the glaciers at Glacier National Park would disappear by 2020 due to global warming.
As it turns out, higher-than-average snowfall in recent years upended computer model projections from the early 2000s. The NPS based its claim that glaciers “will all be gone by the year 2020” on those projections, according to federal officials.
“Glacier retreat in Glacier National Park speeds up and slows down with fluctuations in the local climate,” the U.S. Geological Survey, which monitors Glacier National Park, told The Daily Caller News Foundation.
“Those signs were based on the observation prior to 2010 that glaciers were shrinking more quickly than a computer model predicted they would,” USGS said. “Subsequently, larger than average snowfall over several winters slowed down that retreat rate and the 2020 date used in the NPS display does not apply anymore.”
