Roundup:The Melting World, Frozen Stories and Ice Artifacts

Spread the News:ShareAlpine glaciers have already begun to disappear worldwide “As world temperatures soar, public outcry has focused on the threat to polar ice sheets and sea ice. Yet there is another impact of global warming—one much closer to home—that spells trouble for Americans: the extinction of alpine glaciers in the Rocky Mountains. The epicenter of the crisis is Glacier National Park, Montana, whose peaks once held one-hundred-and-fifty glaciers. Only twenty-five survive. The Park provides a window into the future of climate impacts for mountain ranges around the globe. The Alps, Andes, Cascades, Rockies, and Himalayas are suffering staggering losses. Glaciers provide more than fifty percent of our freshwater needs worldwide—for drinking, irrigation, and hydroelectric power. What’s more, alpine ice feeds innumerable watersheds that harbor ecosystems crucial to fish and wildlife. Nowhere is this truer than in the mountains of Montana.” Read more about the story, click here.   FROZEN STORIES – Discoveries in the Alpine glaciers “Climate change also has its archaeological aspect. It can bring to light what has been hidden under glacial ice for a very long time. Ötzi was not the only lucky find of the last decades. Many other objects have been exposed from the ice,recounting exciting stories from a distant past. And every new discovery gives rise to the question: What was it that drove people onto the glaciers for thousands of years? FROZEN STORIES is an exhibition of rare and in some cases only recently discovered finds from the glacier regions of the Alps, some of them appearing in public for the first time.A multimedia tour with animations, videos and original finds explains the glacier phenomenon to visitors in all its exciting topicality.” Read more about frozen story,click here.   Swiss rush to find ice artifacts as glaciers melt “With Swiss glaciers expected to melt away within a half-century, a Swiss cultural institute and a graduate student in the canton (state) of Graubuenden have launched a pilot project through the end of 2015 to gather artifacts trapped long ago in the ice that are now turning up. The clock is ticking, they say, because once the ice melts away the items will no longer be preserved. Leandra Naef, who has a master’s degree in prehistoric archaeology, told Swiss news agency swissinfo.ch that the project in eastern Switzerland’s mountains “has to happen now, or else it will be too late, if it’s not already too late.”   Read more about glaciers melt, click here.

Roundup: Raging Fires, Racing Bikes, Rushing Water

Spread the News:Share Elite Team Battling Growing Wildfire in Glacier National Park As Tourists Flee “A wildfire in Montana’s Glacier National Park chased hundreds of people from their campgrounds and cabins in the middle of peak tourist season. A management team that responds only to the nation’s highest-priority fire took command Thursday night. More than 200 firefighters backed by helicopters and fire engines planned to attack the blaze’s northeast flank, which was the biggest threat to a hotel and campground that was evacuated Wednesday, and to find a safe place to begin constructing a fire line, fire information officer Jennifer Costich said. The 4,000 acre fire started Tuesday, and officials moved quickly to evacuate hotels, campgrounds and homes, including people in the small community of St. Mary.” Read more about Glacier National Park’s fire here.   Have You Seen This? Insane glacial bike race “Welcome to Megavalance… a four-day event with over 1,400 participants from around the world who attempt to ride 18 miles down a glacier in France on mountain bikes. Riders go from Le Pic Blanc (10,827 feet) to Allemont (2,362 feet), slipping and sliding the whole way.” Read more about the race here.   Central Asia Floods Reawaken Glacier Anxieties “Floods across Central Asia over this past week are highlighting the perils of failing to adopt robust water-management measures and put adequate early-warning systems in place. Tajikistan has been the worst hit, with abnormally high temperatures causing rapid snow and glacier melts. The country is 93 percent covered by high mountains, making it particularly vulnerable to landslides and flash floods. Dozens of homes have been destroyed and at least a dozen people killed.” Read more here. Spread the...

Glacier Retreat Threatens Insect with Extinction

Glacier Retreat Threatens Insect with Extinction

Spread the News:ShareAs glaciers retreat, a species of glacier-dependent stonefly faces extinction. In 2010, the Center for Biological Diversity petitioned for Zapada glacier, a western glacier stonefly only found in alpine streams of Glacier National Park, Montana, to be listed as endangered species under the U.S. Endangered Species Act. This species – one of more than 3500 species of stonefly –  is highly restricted to cold, glacial meltwater with limited dispersal ability. Now, in an effort to save this endangered stonefly, the Center for Biological Diversity filed a lawsuit against the U.S. Fish and Wildlife Service to address the urgency of protecting this stonefly. The insect could potentially be taken to other clean cold streams outside its established range, perhaps further north or at higher elevation where it might survive – but time is running out. Species evolve to survive in specific temperature ranges; however, when the environmental conditions have exceeded the range, species are unable to adapt to new conditions immediately. Climate change has put many species in danger, but this is the first time that an insect species has been threatened with extinction by glacier retreat. “Protection can’t come soon enough for this stonefly,” said Tierra Curry, a senior scientist at the Center for Biological Diversity. “Glacier National Park will have no glaciers in 15 years if we don’t take action to curb climate change.” Stoneflies are a particularly ancient order of insects that spend most of their lives in water. They are considered the most sensitive indicators of water quality in streams as they require fresh, clean water and don’t tolerate pollution. The insects have a one to two-year life cycle starting in the nymph stage in fresh meltwater. They usually emerge from the water in late spring when the stream is uncovered by melting snow. Z. glacier has a narrow temperature preference around 3.3 degrees Celsius. It is this narrow temperature preference that makes this insect especially susceptible to climate change. Between 1960 to 2012, the average summer temperature in Glacier National Park has risen by approximately 1 degree Celsius. Additionally, since 1850, 125 of the 150 glaciers in Glacier National Park have melted away while the remaining 25 are predicted to disappear by 2030. The loss of glaciers as well as restricted suitable environmental conditions and limited dispersal ability of the stonefly threaten the species’ ability to survive. Few studies have investigated the impacts of climate change on alpine species distributions. To compensate for this knowledge gap, J. Joseph Giersch from US Geological Survey and other researchers looked at the current status and distribution of Z. glacier. Their results were published in Freshwater Science. Giersch et al. sampled 6 alpine streams, where Z. glacier was historically known to live, to examine the relationship between species occurrence and environmental variations of temperature and glacial extent. In order to identify the current geographic distribution and distinguish Z. glacier from the other 6 Zapada species in Glacier National Park, the researchers used morphological characteristics, the outward appearance of adults and the DNA of nymphs. Giersch et al. identified 28 suitable alpine locations in Glacier National Park as potential habitats for Z. glacier. From this study, Z. glacier was only found in 1 of the 6 historically occupied streams – the outlet of Upper Grinnell Lake. The results suggest increased temperature and glacier retreat have already caused local extinction of Z. glacier from several historical locations. The stonefly was also detected in 2 new high-elevation locations in Glacier National Park. Therefore, only 3 out of the 28 potential habitats have Z. glacier. The results indicate that the historical distribution of...
