<P>BILLINGS – Glacier National Park has lost two more of its namesake moving
icefields to climate change, which is shrinking the rivers of ice until they
grind to a halt, the U.S. Geological Survey said Wednesday.</P>
<P>Warmer temperatures have reduced the number of named glaciers in the
northwestern Montana park to 25, said Dan Fagre, an ecologist with
the agency.</P>
<P>He warned the rest of the glaciers may be gone by the end of
the decade.</P>
<P>“When we’re measuring glacier margins, by the time we go home the glacier is
already smaller than what we’ve measured,” Fagre said.</P>
<P>The latest two to fall below the 25-acre threshold were Miche Wabun and
Shepard. Each had shrunk by roughly 55 percent since the mid-1960s. On a local
scale, fewer glaciers means less water in streams for fish and a higher risk for
forest fires. More broadly, Fagre said, the fate of the glaciers offers a
climate barometer, indicating dramatic changes to some ecosystems already
under way.</P>
<P>While the melt-off shows the climate is changing, it does not show exactly
what is causing temperatures to rise.</P>
<P>In alpine regions around the world, glacier melting has accelerated in recent
decades as temperatures increased. Most scientists tie that warming directly to
higher atmospheric concentrations of greenhouse gases such as
carbon dioxide.</P>
<P>Some glaciers, such as in the Himalayas, could hold out for centuries in a
warmer world. But more than 90 percent of glaciers worldwide are in retreat,
with major losses already seen across much of Alaska, the Alps, the Andes and
numerous other ranges, according to researchers in the United States
and Europe.</P>
<P>In some areas of the Alps, ski resorts set atop glaciers have taken drastic
measures to stave off the decline, such as draping glaciers in plastic sheeting
to keep them cooler.</P>
<P>It could prove a losing battle: Scientists working for the United Nations say
the last period of widespread glacial growth was more than three decades ago,
lasting only for a few years.</P>
<P>Since about 1850, when the Little Ice Age ended, the trend has been
steadily downward.</P>
<P>The area of the Rocky Mountains now within Glacier National Park once boasted
about 150 glaciers, of which 37 were eventually named.</P>
<P>Fagre said a handful of the park’s largest glaciers could survive past 2020
or even 2030, but by that point the ecosystem would already be
irreversibly altered.</P>
<P>Fagre said geological evidence points to the continual presence of glaciers
in the area since at least 5000 B.C.</P>
<P>“They’ve been on this landscape continually for 7,000 years, and we’re
looking at them disappear in a couple of decades,”
he said.</P></DIV></BODY></HTML>
