It’s an oft-repeated statistic that the glaciers at Montana’s Glacier National Park will disappear by the year 2030.

But Daniel Fagre, a U.S. Geological Survey ecologist who works at Glacier, says the park’s namesakes will be gone about ten years ahead of schedule, endangering the region’s plants and animals.

The 2030 date, he said, was based on a 2003 USGS study, along with 1992 temperature predictions by the UN’s Intergovernmental Panel on Climate Change (IPCC).

“Temperature rise in our area was twice as great as what we put into the [1992] model,” Fagre said. “What we’ve been saying now is 2020.”
