PhotoFriday: When I am Laid in Earth

Spread the News:ShareThe Lewis Glacier on Mount Kenya is one of the most surveyed tropical glaciers on Earth, and has been monitored and mapped regularly since 1934. In 2010, scientists found that the Lewis had shrunk by 23 percent in just the previous six years. The New York Times reports, “Our glaciers, we’re told, are disappearing freakishly fast, but fast for a glacier can still be too slow for the human imagination to seize on.” How do we document this change, and raise awareness of glacial retreat? Award-winning photographer Simon Norfolk answered this question through photography.  His series, When I am Laid in Earth was developed in collaboration with Project Pressure, a nonprofit organization that aims “to photograph and publish the world’s vanishing and receding glaciers, and to document first hand the environmental impact of climate change.” Norfolk’s photo series relied on historical maps and GPS data to mark the contours of the glacier’s retreat and, in the middle of the night, light those lines on fire.

Roundup: Glacier dynamics, retreat in Turkey, and theological meaning

Spread the News:ShareBefore and after: Glacier dynamics and the collapse of ice shelves in Antartica  “Following the disintegration of the Larsen B Ice Shelf, Antarctic Peninsula, in 2002, regular surveillance of its ∼20 tributary glaciers has revealed a response which is varied and complex in both space and time. The major outlets have accelerated and thinned, smaller glaciers have shown little or no change, and glaciers flowing into the remnant Scar Inlet Ice Shelf have responded with delay… Through this study, we seek to improve confidence in our numerical models and their ability to capture the complex mechanical coupling between floating ice shelves and grounded ice.” Read more here.   Turkish glaciers disappearing “Researchers and citizens have known for some time that Turkey’s glaciers are shrinking. Now scientists have calculated the losses and found that more than half of the ice cover in this mountainous country has vanished since the 1970s. A team of researchers from Ege University (Turkey) and NASA’s Goddard Space Flight Center analyzed four decades of Landsat satellite data to document this steady decline. The team, led by Dogukan Dogu Yavasli (Ege), published their results in June 2015 in the journal Remote Sensing of Environment.” More here.   Central Asian expedition revisited “The De Filippi expedition reached Bombay in August 1913, and, during the next 12 months, carried out extensive explorations of Western Himalaya, Karakorum, and Chinese Turkestan. There are several reasons for remembering the De Filippi expedition to Central Asia: (1) a real interest in a past and present neuralgic area comprising several states, in particular Pakistan, China, and India, (2) the renewed attention in the subject of exploration and Italy’s special contribution in this field, (3) the need—now finally acknowledged—to protect and make appropriate use of our scientific heritage, and (4) an interest in new forms of tourism… One hundred years after the expedition, we focus the attention on the scientific results obtained by persons that we do not hesitate to define as extraordinary, but now partly forgotten.” More here.

PhotoFriday: Is the Mountain Out?

Spread the News:ShareEvery city has its slang. In Seattle, Washington, and throughout the Puget Sound region, the phrase “the mountain is out” is part of the everyday weather lexicon. Seattleites refer to “the mountain” and no one doubts which mountain is being discussed. Towering 14,410 feet above sea level, Mount Rainier is the most glaciated peak in the contiguous U.S and can be seen from far and wide. There are 25 major glaciers on Mount Rainier. According to the US National Park Service, “the Emmons Glacier has the largest area (4.3 square miles) and the Carbon Glacier has the lowest terminus altitude (3,600 feet) of all glaciers in the contiguous 48 states.” “Is the mountain out?” is another way to say, “is Rainier visible?” or simply “is it sunny?” Especially in Seattle, where the weather is notoriously overcast and grey, clear skies reveal a beautiful mountain-scape.

He found that the mountain was “out” 83 times during 2012, roughly once every 4 to 5 days. The phrase has inspired artists at the Seattle Times, and even landed its very own Twitter feed, with regular updates on Rainier’s status.

Roundup: Fish in Patagonia, Film in Kashmir & Glacial Georgia

Spread the News:ShareOne Fish, Two Fish: Black Southern Cod maintain a more diverse diet when near glacier meltwater areas “The black southern cod, Patagonotothen tessellata, is the most important notothenioid fish species in terms of abundance in southern Chilean Patagonia. However, studies on its trophic ecology are scarce. [This study assessed] the spatial variation in the diet of P. tessellata between two localities, one with oceanic influence (Staples Strait) and another with continental influence (Puerto Bories)… The black southern cod presents spatial differences in diet composition among contrasting environmental localities… The results provide evidence of two dietary patterns depending on the type of environment in which they are distributed, highlighting the potential role of the environmental variables on the availability and abundance of potential prey and in structuring diet.” More here. Glaciers in the Spotlight: Salman Khan films dramatic scene at Thajwas glacier, Kashmir “No doubt Salman Khan’s films are incredible exciting and dramatic, but his forthcoming release ‘Bajrangi Bhaijaan’ has even gotten better… ‘The Bajrangi Bhaijaan climax was shot at the base of the Thajwas glacier outside Sonamarg. Located at 10,000 feet above sea level… the 300 strong technical crew had to trek for an hour through snow every morning to reach the location. Added to this was were the 7000 extras that we had on set every day. Transporting them in hundreds of buses and then embarking on the hour-long trek was a huge logistical challenge for the production. To add to their woes was the sub zero temperatures and hail storms that would interrupt the shoot,’ said Kabir Khan who has previously worked with Salman in ‘Ek Tha Tiger.’” Read more here.   Glacial Melt in Georgia, Communities Threatened by Avalanche “Considering its size, Georgia has a large number of glaciers. In the mountains of Georgia, there are about 786 registered glaciers, with a total area of about 550 km. About 82.5 % are in the upper courses of the Kodori, Inguri, Rioni, and Tereck rivers. For the past 150 years, significant glacier retreat (0.8–1.7 km) and shrinking of their area by 16 % has been observed. Since the middle of the 1940s, the glaciological situation has been characterized by a sharp reduction in the glacial area, but with the simultaneous increase in their number as glaciers disintegrated into separate smaller ones, although at the same time separate movements have also taken place. Avalanches are common in Georgia. Nearly 340 inhabited places are under the threat of avalanche attacks. About 31 % of the territory of Georgia is subject to avalanches (18 % in eastern and 13 % in western Georgia).” More here. Spread the...

PhotoFriday: Wildfires Rage in Alaska

Spread the News:ShareUnseasonable heat in Alaska combined with winds and low humidity have triggered major wildfire outbreaks in the Northern state. According to a status report from the Alaska Interagency Coordination Center, as of Wednesday, June 24, there were 278 active wildland fires state-wide. The Healy Lake Fires grew to 10,000 acres earlier this month, doubling in less than 24 hours. The Stetson Creek Fire started when lightning struck on the Kenai Peninsula. The fire had consumed about 400 acres last week. This May was the hottest May on record in Alaska, according to data that goes back 91 years.  The immediate cause of the high temperatures can be attributed to the development of an El Niño event in the eastern Pacific, which can trigger extreme climate events around the world. On a longer timescale, Alaska has warmed twice as fast as the national average over the last 50 years, the US Environmental Protection Agency found.

Balinda O’Neal Arial view of forest fire coverage shows proximity to glaciers in Alaska. Credit: NASA “The number of large wildfires (larger than 1,000 acres) suddenly increased in the 1990s, and the 2000s saw nearly twice as many large wildfires as the 1950s and 60s,” according to Climate Central. This increase has been concurrent to rising temperatures. The U.S. National Climate Assessment reports that the area impacted by wildfires in Alaska will double by 2050, and triple by 2100 if emissions continue at present rates and warming continues. The heat means trouble for Alaska’s glaciers, too. A new study from researchers at the University of Alaska, Fairbanks found that from 1994 to 2013, Alaskan glaciers have lost 75 gigatons (or 75 billion metric tons) of ice per year. That’s equivalent to half the total ice loss of Antarctica.
