Roundup: Nepal Symposium, Microrefugia, Climate Change

2 March 2015, by

Symposium on Glaciology in High-Mountain Asia (1 – 6 March, 2015) “The high mountains of Asia are estimated to contain one of the greatest concentrations of glacier ice outside the polar regions, and are the headwaters of rivers which support agriculture and livelihoods of over one billion people. Changes in snow, ice, and permafrost due […]

Glaciers Influence Marine Invertebrates in Chile

25 February 2015, by

Zooplankton are tiny creatures that drift in water bodies. A recent study by Meerhoff et al. in Progress in Oceanography describes linkages which connect them with glaciers. The researchers observed meroplankton—organisms which have planktonic features in their larval stages, but live sessile in the bottom as adults. They worked in the fjords of the Baker […]

Dam Spill Threats at a Gold Mine in Kyrgyzstan  

17 February 2015, by

In light of the Mount Polley tailings dam spill in British Columbia, Canada, environmental activists in Kyrgyzstan are ringing alarm bells over a possible scenario of a similar outburst at Petrov Lake near the Kumtor gold mine project. At Mount Polley, the tailings dam at a copper and gold mine burst in August last year, spilling 25 […]

Roundup: Hindu Kush glaciers, Tibetan lakes and science vs. politics in Chile

16 February 2015, by

Glacier changes in Hindu Kush Himalayas                  “The fate of the Hindu Kush Himalayan glaciers has been a topic of heated debate due to their rapid melting and retreat. The underlying reason for the debate is the lack of systematic large-scale observations of the extent of glaciers in […]

Glacier Melting Sets Free Organic Carbon

12 February 2015, by

Research has shown that glaciers have a greater role than was previously known in the movement of organic carbon into and through aquatic ecosystems, including the oceans. Organic Carbon (OC) refers to carbon contained in organic compounds that is originally derived from decaying vegetation, bacterial growth, and metabolic activities of living organisms. It serves as […]

Tracking Glaciers From Space: GLIMS

11 February 2015, by

In 1994, an international group of scientists came together to form GLIMS (Global Land Ice Measurements from Space), a worldwide initiative to monitor and study glaciers using satellite data. For at least one hundred years, scientists had primarily used traditional field measurements to track glacier dynamics, but field data are by necessity limited in scope, […]

Adventures in Glaciology: Juneau Icefield Research Program

10 February 2015, by

By Allen Pope A lot of people are fascinated by glaciers. Some people even think glaciers are cool enough that they are wiling to spend an entire summer skiing across the Juneau Icefield, digging snow pits, researching glacier dynamics, and seeing some awesome sunsets along the way. Welcome to the Juneau Icefield Research Program, better […]

Scientists Learn to Drone in the Himalayas

5 February 2015, by

As glaciers around the world melt in response to climate change, scientists are rushing to map and catalog the precise ways in which they are changing. They have new allies in this fight: drones. But first, scientists have to learn how to use and operate them. In late January, an organization dedicated to sustainable mountain […]

Melting Glaciers Give Earth a Pop

3 February 2015, by

Though the Earth often seems solid and fixed, it is not. You’ve probably heard of continental drift—the horizontal movement of continent-sized bodies of rock—but fewer of you may appreciate that the earth can move vertically as well. Studies have shown that North America and Europe are rebounding, slowly but steadily, due to the removal of thick ice sheets […]

Earthquakes Rattling Glaciers, Boosting Sea Level Rise

30 January 2015, by

Talk of earthquakes likely calls to mind giant fissures opening up along the earth’s crust, the trembling of rock, buildings crumbling to their knees and, depending on your age and cast of mind, the love of Superman for Lois Lane. But it does not likely conjure up images of giant tongues of sliding ice or […]

Roundup: New Stories on Black Carbon

26 January 2015, by

We feature three stories, all of which focus on black carbon. This atmospheric pollutant plays an important role in accelerating glacier retreat. Moreover, policies can be designed to reduce it, by supporting alternative fuels and improved technologies. Reductions in black carbon also bring health benefits, since this substance leads to pulmonary diseases. Story 1: Ice […]

Little Auk Upends Arctic Climate Change Models

22 January 2015, by

In July of 2013, a team of scientists from France, Russia and the United States descended upon an uninhabited archipelago in the Russian Arctic called Franz-Josef Land, the northern most archipelago in the world. There they spent two months at Tikhaya Bay on Hooker Island, one of the archipelago’s 191 islands, tagging and studying a […]
