Volcano in Chile Causes Evacuations, Damage

24 April 2015, by

A major eruption of Calbuco,  a volcano in southern  Chile, has melted glacier ice, creating large flood events. The eruption on 22 April came as a near-total surprise, since it had been preceded by only two hours of increased seismic activity, according to Chile’s National Service of Geology and Mines. It shot incandescent masses of lava […]

Glacier Retreat Brings New Islands

21 April 2015, by

In some parts of the world, new islands are forming due to glacier retreat. Glaciers, dynamically responding to the change in temperature and precipitation, reveal the big picture of climate variability and change. During the Little Ice Age (LIA) with cooler temperatures, glaciers around the world grew substantially, from approximately 1350 to 1850. It was […]

New Discovery: Record of Glacial Cycles on Sea Floor

14 April 2015, by

The history of the world’s hot and cold periods can be read on the ocean floor, according to a new study. The Earth has gone through cycles of glacial periods, when the great continental ice sheets advanced during colder periods, and interglacial periods – warmer climate cycles like like present day. These glacial-interglacial cycles are […]

Ice Cave Collapses On Mt. Hood

7 April 2015, by

In the warmest winter on record the roof of a highly popular ice cave on Mt. Hood, Oregon fell in. The Snow Dragon ice cave at the bottom of the Sandy Glacier on Mt. Hood was first publicly documented in 2011 by Brent McGregor and Eddy Cartaya– we covered their experience documenting the Sandy Glacier last October. […]

Round Up: Melting in Alaska, Biking Madness, Glacier Art

6 April 2015, by

Gulf of Alaska Experiencing Large Flushes of Glacial Melt Water “The collective freshwater discharge of this region is more than four times greater than the mighty Yukon River of Alaska and Canada, and half again as much as the Mississippi River. While scientists had indeed noticed this runoff, until now they had no idea the […]

Sirens Warn Chilean Town of Impending Volcanic Eruption

5 April 2015, by

Siren blasts created great concern in the southern Chilean town of Pucón on the afternoon of Easter Sunday. The residents feared that a second eruption of Mount Villarrica, a large glacier-covered volcano close to the town, would occur at any moment. The dramatic lava flows and enormous ash clouds from the first eruption on March […]

New Report Addresses Mountain Sustainability

1 April 2015, by

A major new report provides a thorough summary of research and an innovative discussion of development efforts in mountain regions. This report, titled ‘Mountains and Climate Change: A Global Concern,’ was published in December 2014 by the Mountain Partnership as part of the UN Sustainable Mountain Development Series. The Mountain Partnership is an international organization, dedicated to […]

Science on Trial at Pascua Lama

26 March 2015, by

Chile’s environmental court ruled on Monday that the Pascua Lama gold mine is not responsible for damage done to three glaciers near the mine site. Some argue its a setback for Chilean science.

Glacial Outburst Floods in Greenland Discharge Mercury

25 March 2015, by

Mercury contamination has long been a threat to animal carnivores and human residents in the Arctic. Mercury exports from river basins to the ocean form a significant component of the Arctic mercury cycle, and are consequently of importance in understanding and addressing this contamination.  Jens Søndergaard of the Arctic Research Centre of Aarhus University, Denmark […]

Glacier Meeting in Kathmandu

24 March 2015, by

Kathmandu, a Nepalese valley with a rich cultural and religious history, was the venue for the International Symposium on Glaciology in High-Mountain Asia early this month. From March 1 to 6, 240 scientists from 26 countries gathered there to further interdisciplinary understanding of the science of glaciers, snowpack, and permafrost in the high-mountain Asia region—the Himalayan, […]

Roundup: Rock Avalanche, Melting Sound, Black Carbon

23 March 2015, by

Landslides on Glaciers “The chapter looks mainly at massive rock slope failures that generate high-speed, long- runout rock avalanches onto glaciers in high mountains, from subpolar through tropical latitudes. Drastic modifications of mountain landscapes and destructive impacts occur, and initiate other, longer-term hazards. Worst-case calamities are where mass flows continue into inhabited areas below the […]

Peruvian Demands Payment for Climate Change

19 March 2015, by

Peruvian farmer and mountaineering guide Saul Luciano Lliuya, and the town of Huaraz where he lives, long known as the “Switzerland of Peru,” may go down in climate-change history.
