Melting glaciers a concern for Glacier Park's tourism industryBy MICHAEL JAMISON of the Missoulian missoulian.com | Posted: Thursday, April 8, 2010 6:00 am
WEST GLACIER - A warming climate is changing the face of Glacier National Park, and some now worry the transformation threatens not only downstream ecosystems but also the region's important tourism economy.
"Tourism brings about $3 billion into Montana every year," said Rhonda Fitzgerald, an innkeeper and member of the state tourism advisory council. "In the Glacier region, it's about $1 billion per year. Those are the economic facts."And then there are the climate change facts.
Between 1900 and 1979, the Glacier Park area experienced an average of 181 days every year when the temperature dipped below freezing. Between 1980 and 2005, warming had reduced the number of below-freezing days to 152.

No More Glaciers in Glacier National Park by 2020?

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."
