The Funeral for Iceland’s OK Glacier Attracts International Attention

On August 18, about 100 people, including Iceland’s Prime Minister Katrin Jakobsdottir and former President of Ireland Mary Robinson, hiked for two hours to attend a somber event. The gathering was in memory of OK Glacier, which had melted so extensively that, in 2014, scientists pronounced it dead. It is the first Icelandic glacier lost to climate change. 

To be considered a glacier, an ice mass needs to have movement. OK melted so significantly that it no longer had the mass to move under its own weight and so no longer met the criteria of a glacier.

The event received international coverage, appearing in Time, the Washington Post, the Associated Press, and the BBC, among other major publications. In a New York Times opinion piece, PM Jakobsdottir called the gathering “a local ceremony but a global story.”

“Glaciers are melting all across the world, contributing enormously to rising sea levels,” she wrote. “Himalayan glaciers help regulate the water supply of a quarter of humankind. Natural systems will be disrupted.”

Two researchers, Cymene Howe and Dominic Boyer, first proposed commemorating the loss of OK Glacier. The Rice University scientists produced a documentary called “Not Okin order to draw attention to the plight of the glacier. In the process of making the film, Howe and Boyer had the idea to hold a kind of memorial for OK, which is shorthand for Okjökull.

Howe and Boyer attended the August 18 commemoration.

“As we neared the site of the lost glacier, we followed an Icelandic hiking tradition where you walk in silence, think of three wishes, and never look back,” Howe told GlacierHub in an email. “Completing that last 100 meters in silence was exceptionally poignant. We were stepping forward, to be sure, but also reflecting on what it means to say goodbye to the world that we have known.”

Once the participants reached OK, they reflected on the tragedy of OK’s disappearance and on the need to protect existing glaciers.

“At the site of the memorial we had words of recognition, remorse, and— more than anything—calls to action,” Howe said.

Echoing the sentiment, Robinson told the Associated Press: “The symbolic death of a glacier is a warning to us, and we need action.”

OK’s demise and the commemoration in Iceland has already had ripple effect. On September 22, mourners will gather at a funeral for the Pizol Glacier in eastern Switzerland.

Snow Algae Thrives in Some of Earth’s Most Extreme Conditions

A new study found snow algae on Nieves Penitentes at high elevations in the Chilean Andes.

“The expedition was an epic and very arduous trip to a remote mountain,” Steven Schmidt, a University of Colorado, Boulder professor and one of the paper’s authors, told Glacierhub. “[The] original goal was to sample a lake below a remnant glacier high on the mountain, but the lake was frozen solid and the winds were horrendous,” Schmidt explained, “so we worked lower on the mountain and carried out the first ever search for life on Nieves Penitentes.”

Nieves Penitentes are elongated ice structures. They form when windblown snow banks build up and melt due to a combination of high radiation, low humidity, and dry winds. The snow melts into the pinnacle-shape which earned Penitentes their name—they are said to resemble monks in white robes paying penance. Penitentes are important to the dry, high-altitude areas where they are found because they can be a periodic source of meltwater for the rocky ground.

Schimdt described how the researchers were surprised to find patches of red ice on the sides of some of the penitentes. “We took samples from these patches and later found that they contained some unique snow algae and a thriving community of other microbes,” he told GlacierHub.

The study was published the journal of Arctic, Antarctic, and Alpine Research

“Snow algae are microscopic plant-like organisms that are able to live on and within the snowpack,” plant and algal physiologist Matthew Davey, who was not involved in the study, told GlacierHub. Snow algae is also known as watermelon snow because of the color it creates on the surface of snow and ice. The snow’s watermelon hue is caused by an abundance of natural reddish pigments called carotenoids which also shield the algae from ultraviolet light, drought, and cold, contributing to their ability to survive in extreme environments.

Researchers don’t entirely understand how the algae bloom in high density given the low temperatures and high light levels they live with. “There is evidence that they can be deposited by wind, they could already be in the rock surface from previous years or they could be brought by animals,” Davey explained. “Once the snow has melted slightly, so there is liquid water, the algae can reproduce and bloom within days or weeks. During this time they can start green, then turn red, or stay green or stay red—it depends on the algal species,” he said of their formation process. 

The samples of snow algae were collected from Penitentes on the Chilean side of Volcán Llullaillaco. It is the second tallest active volcano in the world after Ojos del Salado and it sits on Chile’s border with Argentina. The Penitentes were between 1-1.5 meters tall. The presence of snow algae on Penitentes is notable because the algae can change the albedo of ice and increase melting rates.

The study describes the environment that the samples were collected in as “perhaps the best earthly analog for surface and near-surface soils on Mars,” opening the door for implications in astrobiological research. The high elevation where the snow algae was found is responsible for the conditions that create an almost extraterrestrial environment; there are very high levels of ultraviolet radiation, intense daily freeze-thaw cycles, and one of the driest climates on the planet. 

Penitente-like structures were recently found on Pluto and possibly on Europa, one of Jupiter’s moons. In the context of these discoveries, Schmidt said that “penitentes and the harsh environment that surrounds them provide a new terrestrial analog for astrobiological studies of life beyond Earth.” The finding in the new study that “penitentes are oases of life in the otherwise barren expanses” pushes the boundaries of the current understanding of the cold-dry limits of life.

Lead author Lara Vimercati reflected on the study’s broader implications. “Our study shows how no matter how challenging the environmental conditions, life finds a way when there is availability of liquid water,” she said.

What Happens to Species Diversity as Glaciers Melt?

Published in July 2019, a study looked at the effects of melting glaciers on seafloor species diversity in Antarctica.

As glaciers melt, more sediment is released into the surrounding waters and can smother seafloor communities. As part of the same process, more icebergs are created which can scrape the bottom of the ocean, removing the top layers of sediment, known as soft sediment. 

Soft sediment contains a great deal of life and plays an important role in marine ecosystems The study explains that it is one of the “key components of energy flow through food webs” and is important “in sedimentary processes especially nutrient and carbon cycling, waste breakdown and removal.” 

The authors wrote that it was “the first study to comprehensively analyse the composition of Antarctic soft sediment metazoan communities across all size classes, from < 1 mm up to 10 cm, in two geographically distinct coves.”

The study found that “in contrast to findings from rocky substrata, there was no evidence of an effect of typical Antarctic stressors of iceberg scour and intense seasonality. As at other latitudes, organic content of the sediment was most strongly correlated with community structure, suggesting that increased sedimentation from run-off from melting glaciers may be the main climate change effect on these communities.”

Credit rating agency buys climate risk firm

A New York Times article explains the credit rating agency Moody’s purchase of Four Twenty Seven, a firm that measures climate risk:

“Sudden shocks such as floods, wildfires or storms can hurt businesses and send residents fleeing, taking away the tax revenue that governments use to pay their debts. And longer-term threats — such as rising seas or higher temperatures — can make those places less desirable to live in, hurting property values and, in turn, the amount raised by taxes.

Rating agencies translate those risks, along with more traditional factors such as a government’s cash flow and debt levels, into a credit rating, which communicates to investors the odds that a government will be unable to repay its bondholders. Lower ratings generally mean that borrowers need to offer investors a higher return to account for that risk.

Following a string of deadly hurricanes and wildfires in 2017, Moody’s, along with S&P Global and Fitch Ratings, issued reports warning state and local governments that their exposure to climate risk could affect their credit ratings.”

Iceland to Commemorate the Demise of Okjökull Glacier

Iceland is home to hundreds of glaciers, but in 2014 the number fell by one: the former Okjökull glacier was the first Icelandic glacier to melt due to human-caused climate change.

On August 18, 2019, an event will be held to install a monument to the lost glacier. It was organized primarily by a group of researchers from Rice University in Houston. Participants will include geologists, authors, members of the Icelandic Hiking Society and the general public. In a press release from Rice University, anthropologist Cymene Howe who produced a documentary about Ok said, “by marking Ok’s passing, we hope to draw attention to what is being lost as Earth’s glaciers expire. These bodies of ice are the largest freshwater reserves on the planet and frozen within them are histories of the atmosphere. They are also often important cultural forms that are full of significance.”

During the event, which the organizers have termed an Un-glacier Tour, a metal plaque will be installed which reads “Ok is the first Icelandic glacier to lose its status as a glacier. In the next 200 years all our glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it.” The words were written by Icelandic author Andri Snær Magnason who will be present at the ceremony. Howe also said that it is the first monument to be installed for a glacier lost to climate change.

The plaque also lists the carbon dioxide concentration “415 ppm,” referring to the concentration recorded in May 2019 at Mauna Loa Observatory. 

Ok is now considered dead ice. Director of the North Cascades Glacier Climate Project, Mauri Pelto told GlacierHub that “stagnant ice that no longer moves is dead ice; a glacier by definition has movement.” In other words, glaciers continuously build up new ice and flow as a result of that process. When an ice mass loses has those qualities it can no longer be called a glacier and is instead dead ice.

“Iceland is not the first country on our planet to lose a glacier due to increasing climatic changes, and it is not the last,” geographer M Jackson told GlacierHub. She continued, saying “we are losing glaciers worldwide at unprecedented rates.” Other countries that have already lost glaciers include Bolivia, the United States, and Venezuela and many other places are on their way to losing their glaciers.

Despite the unfortunate prevalence of glacial retreat, the loss of a glacier in Iceland is particularly poignant because of the country’s relationship to its ice and glaciers. Icelandic anthropologist Gísli Pálsson told GlacierHub he thinks glaciers “have strong significance in Icelandic culture and history.” He elaborated saying, “there is a slogan about Iceland, ‘it is the land of fire and ice,’ the name ‘Iceland’ of course highlights the ice connection, and, historically, there have been scholars on glaciers, some glaciers have been travel routes and have been located between communities without any other connections so there were frequent travels across them for trading.”

Pálsson was a member of the first Un-Glacier tour in the summer of 2018. He described the day, saying “it was a long ride into the highlands and once we got there the mountain was covered with fog and it was a bit spooky. We started to walk uphill and soon the sky cleared. Once we got up there it was stunning scenery of the nearby mountains and we walked around the crater almost in a complete circle and could soon see the remains of the sleet and ice in the bottom of the crater.”  He said the tour was composed of about 20 people and they “talked about the climate, glaciers, and the history of this particular one, and plans for an event a year later which is now coming up.”

Pálsson explained that the person in the green coat is marking the GPS location of the stone so that when they returned a year later they would know precisely which stone was chosen for the installation of the plaque.

With regard to the Un-Glacier Tour II, Pálsson said “I am unsure if I will be able to go this time, but I wish I could. I’m sure this first symbolic event of paying tribute to a gone glacier will be a well attended and significant event that will later on, with more glaciers under threat, be on record and flagged repeatedly.” M Jackson also had a positive response to the event and said “I’m grateful this memorial has been created, and hope such a stunt will encourage more social and political action to meet climatic changes in the days, months, and years to come.” 

The melting of Ok takes on one meaning for Icelanders and another in the broader context of climate change, but in both circumstances helps to increase awareness of the challenges that climate change will bring about as time goes on.

Photo Friday: Glacier Melt in Bolivia Exacerbates the Nation’s Water Crisis

Photographer James Whitlow Delano has created a series of powerful images of Bolivia’s ongoing water crisis. His photos focus on the Altiplano, the high plateau where the Andes Mountains are at their widest and which crosses the borders of Bolivia, Peru, Chile, and Argentina. La Paz, Bolivia’s capital, is the largest city on the plateau. Families from rural areas are moving into La Paz and its largest satellite city, El Alto, because the agricultural way of life they rely on is no longer viable due to a lack of water. These families move into slums in the cities, like the one captured below, hoping to find better paying jobs.

Rural areas are struggling because the glaciers they rely upon are melting, which means less water for farming or snow for skiing. The lodge shown below was formerly a part of the highest ski resort in the world, but now sits empty because the Chacaltaya Glacier, which filled the adjacent valley, melted entirely in 2009 due to warmer and more frequent El Nino events.

Mountains in the Andes, like Condoriri, currently show what the region would look like without the effects of climate change. Glaciologist Edison Ramirez conducted a study that predicted, however, that the glaciers on the mountain may completely melt over the course of the next thirty years.

The melting of the glaciers has already had negative effects; along the shores of the dried up Lake Poopo sit quinoa plants in desiccated soil. Migration from rural areas to Bolivia’s cities is driven by drought. The difficulties created by drought are contributing to residents’ moves into bigger cities.

Lake Poopo was previously the second largest lake in Bolivia. As of 2015, it sits empty. 

Other lakes and ponds in the Altiplano are at risk of suffering the same fate; below is a pond in the process of drying up. The melting of the glaciers and the lakes they feed is significant because the Altiplano does not get enough rain to support those who live there—It relies on glacial melt to support the human population.

Since the series on Bolivia was posted in late June, @everydayclimatechange has highlighted water shortages in Chennai, India; wildfires in Yosemite; and youth climate strikes inspired by Greta Thunberg, a Swedish youth climate activist.

Rising Temperatures Have Doubled Himalayan Glacier Melt—Study

The Himalayas have a powerful impact on the lives of the people who live near them: They have cultural and religious sway, they play a role in determining regional weather patterns, and they feed major rivers like the Indus, the Ganges, and the Tsangpo-Brahmaputra that millions rely on for freshwater.

A new study published in the journal Science Advances by Ph.D candidate Joshua Maurer of Columbia University’s Lamont-Doherty Earth Observatory concludes that glaciers in the Himalaya melted twice as quickly from 2000 to 2016 than they did from 1975 to 2000. “This is the clearest picture yet of how fast Himalayan glaciers are melting over this time interval, and why,” said Maurer.

Walter Immerzeel, a professor in the University of Utrecht’s department of geosciences, told GlacierHub that “the novelty lies in the fact that they go back until 1975.” He said that scientists already knew “quite well” what the mass balance rates were for the last twenty years or so, but that looking further back and over a wider area provided interesting new information.

Maurer and his co-authors examined ice loss along a 2,000-kilometer-long transect of the Himalayas, from western India eastwards to Bhutan. The study area includes 650 of the largest glaciers in the Himalaya and confirms the results of previous studies conducted by researchers who looked at the rate of mass loss in the Himalaya. 

The new study makes a major contribution by indicating that regional warming is responsible for the increase in melting. The researchers were able to determine this because mass loss rates were similar across subregions despite variations in other factors like air pollution and precipitation that can also accelerate melting.

Immerzeel agreed with the findings. “It is mostly temperature change driving the mass balances,” he said. “It can be locally enforced by black carbon or modulated by precipitation changes, but the main driving force is a rise in temperature.” 

The analysis was conducted using images from declassified KH-9 Hexagon spy satellites which were used by US intelligence agencies during the Cold War. The satellites orbited Earth between 1973 and 1980, taking 29,000 images that were kept as government secrets until relatively recently when they were declassified, creating a cornucopia of data for researchers to comb through.

Maurer and his co-authors used the images to build models showing the size of the glaciers when the images were created. The historical models were then compared to more recent satellite images to determine the changes that occurred over time. Only glaciers for which data were available during both time periods were included in the study.

The new study received widespread media attention. National Geographic, CNN, the New Yorker, and The Guardian, among other major publications, highlighted the study’s conclusion that mass loss in Himalayan glaciers has doubled in the last forty years.

Tobias Bolch, a glaciologist at the University of St Andrews, told GlacierHub the findings should be approached with caution. “The statement about the doubling of the mass loss after 2000 compared to the period 1975-2000 should be formulated with much more care.”

“[Scientists],” he continued, “need to be very careful presenting results about Himalayan glaciers and should communicate them correctly specifically after the IPCC AR4 error, and the wrong statement about the rapid disappearance of Himalayan glaciers.”

Bloch is referring to an error that occurred in 2007, when the IPCC included in its Fourth Assessment Report an inaccurate statement predicting that all Himalayan glaciers would be gone by 2035.

“It is a promising data set, but due to its nature there are large data gaps which need to be filled which makes the data uncertain,” Bolch said.

He added that there is “clear evidence” that mass loss has accelerated in the Himalaya.

A recent report by the International Centre for Integrated Mountain Development, a regional intergovernmental organization in Nepal working on sustainable development in mountains, predicts that the Himalayas could lose 64 percent of their ice by the year 2100.

The large amount of melting that may occur in the coming decades would result in greater quantities of meltwater entering rivers. The Indus River, which millions rely on for drinking water and agriculture, receives about 40 percent of its flow from glacial melt. An increase in meltwater could augment the risk of flooding of the Indus and other rivers in the region. 

Similarly, there may be a greater number of glacial outburst floods. Outburst floods occur when the moraine, or rock wall, which acts as a dam collapses. A collapse can take place for various reasons including if a great deal of water accumulates in a lake from a phenomenon like an increase in glacial melting. Depending on the size of the lake and downstream populations, among other factors, these floods have the potential to cause substantial damage. The largest of these floods have killed thousands of people, swept away homes, and even registered on seismometers in Nepal.

Once glaciers have lost substantial amounts of mass and no longer have large quantities of water to release, the reverse will begin to cause problems: Rivers dependent on Himalayan glacial melt will diminish and drought may become more common downstream. This will negatively affect farming and development in the Himalayan region.

In both the short and long term, according Maurer and his colleagues, glacier melt in the Himalayas will have significant impacts on the livelihoods of those dependent on its towering peaks.

Melting Glaciers in UNESCO World Heritage Sites

A recent study published in the journal Earth’s Future presents the first ever inventory of glaciers in UNESCO World heritage sites. The study authors identified 19,000 glaciers across 46 sites, studied their current state, and projected their changes in mass by 2100. The researchers found that “except for the mostly balanced conditions modeled for Heard and McDonald Islands (Antarctic Islands), substantial ice loss will occur in all natural World Heritage sites.” The study compares glaciers to umbrella species because “their conservation will automatically allow and imply the conservation of other features threatened by global warming” and to keystone species “because of their disproportionately large impacts on nature and societies on Earth.”

The study highlights that “the safeguarding of these iconic and important natural features could mobilize global‐scale conservation and mitigation benefits. As for all glaciers and ice sheets on Earth, their preservation reinforces the compelling priority for strong and rapid reduction of greenhouse gas emissions and thereby a deep modification of human impacts on the climate.”

Artificial Glaciers in the Himalayas

The New Yorker looks at the proliferation of artificial glaciers in the Himalayas: “The first ice stupa was created in 2013, in Ladakh, in Kashmir. Villages in Ladakh, a high mountain-desert region bordered by the Himalayas, largely depend on glacial runoff for water. As the glaciers recede, owing to climate change, the flow of water has become more erratic. Sometimes there’s too much, producing flashflooding; often, there’s too little. The ice stupa, a kind of artficial glacier, is the brainchild of a Ladakhi engineer named Sonam Wangchuk.”

From the New York Botanical Garden: “Focusing on Humboldt’s five-year expedition in South America, Wulf and Melcher incorporate pages of his own diaries, sketches, drawings, and maps to create an intimate portrait of the radical ecologist who predicted human-induced climate change and fashioned poetic narrative out of scientific observation.

Driven by his conviction that the world was a single, interconnected organism, Humboldt was the first to note similarities among climate zones across the world. His work turned scientific observation into poetic narrative that influenced great minds from Goethe to Darwin and Thoreau.”

Event Series Highlights Threats to Tibet’s Glaciers

Tibet accounts for an estimated 14.5 percent of the world’s total glacier mass, but climate change and air pollution are an increasing threat to the nation’s glaciers. The retreat of these glaciers causes grasslands to shrink and permafrost to thaw. It also endangers the water supply of those who rely on the Yangtze, Mekong, Salween, Indus, Brahmaputra, and Yellow Rivers—all of which are fed by water from Tibet’s glaciers.

During the week leading up to World Environment Day, which occurred on June 5, four groups—the University of Washington’s South Asia Center, the Canada-Tibet Committee, the Mountain Resiliency Project, and the Himalayan Mountain International Film Festival—teamed up for series of events in British Columbia and Seattle, Washington to highlight why China needs to address environmental degradation. The groups hoped to bring awareness to the fact that there was too little discussion happening in China or at the United Nations about the negative environmental impacts taking place on the Tibetan Plateau and their impacts on people living downstream.

World Environment Day was established in 1972 when the UN General Assembly passed a resolution creating the celebration. June 5 was chosen because it marked the beginning of the Stockholm Conference, which took place June 5-12, 1972 and was the first, major United Nations summit on environmental issues.

A different country leads the effort each year by choosing a theme for the day that is recognized by more than 143 UN member nations. In the past, host countries and themes have included India and plastic pollution, Angola and the illegal wildlife trade, and Barbados and the dangers of rising sea levels.

China led the 2019 celebration, titled “Beat Air Pollution.” The goal was to promote renewable energy and other green technologies that could help improve air quality around the world. According to the UN World Environment Day website, more than 6 billion people breathe air that puts their health at risk. Nine out of ten people worldwide are exposed to levels of air pollution that exceed World Health Organization guidelines. That exposure is lowering life expectancy and harming economies.

Social activist, founder of the Mountain Resiliency Project, and former GlacierHub writer Tsechu Dolma spoke to GlacierHub about the China-themed World Environment Day events. “Whatever happens on the Tibetan Plateau and in the rest of Asia will impact all of our livelihoods around the world because the Tibetan plateau is home to the largest reserve of freshwater outside of the poles,” she said.

She added that the Chinese government has devoted a great deal of resources to buildings dams on the headwaters of major rivers originating in Tibet, which impacts the water supply for millions of people living in the region.

The events, said Dolma, were also meant to provide a space for Tibetans to share their opinions on China’s air pollution. “Tibetans are considered indigenous people of China,” she said, “and so [the organizers] wanted to elevate indigenous voices on what World Environment Day means for people living within China.”

Dolma stated that she believes that the Chinese government is making an effort to rectify some of the environmental damage it has caused. “It realizes that thousands of people in China are dying from pollution, and the environmental impacts directly undermine the government’s legitimacy for the people,” she said.

The high-profile participation of the Chinese government was, according to Dolma, “their way of putting in an effort.” But, she added, it was picking and choosing which issues to highlight and downplaying its role in perpetuating the problem.

World Environment Day is largely about raising public awareness about environmental degradation and providing a forum for UN nations to outline potential solutions, such as expanding access to public transportation and electric vehicles, encouraging energy efficiency and conservation, and reducing meat and dairy dairy consumption, which produces high amounts of methane emissions. Governments were encouraged to increase investment in renewable energy, while the private sector was encouraged to cut emissions along its supply chains.

A prominent event of 2019’s World Environment Day celebration was the Mask Challenge. Organizers asked participants from around the world to post on social media a photograph of themselves wearing a protective mask and pledging to take some type of action that could help reduce air pollution. Thousands of people across the globe, including singer Ellie Goulding and model Gisele Bundchen, participated in the event using the hashtag #BeatAirPollution.

The UN also turned to social media to highlight science about air pollution, including one study conducted by the National Institute of Research on Glaciers and Mountain Ecosystems in Peru. The study focused on black carbon, which comes from vehicular and industrial emissions, wildfires, and the burning of waste. The soot from those sources can accumulate on the surface of glaciers, which darkens them and increases the amount of sunlight they absorb. China’s air pollution and even the oil fires in Kuwait during the 1991 Gulf War have been sources of black carbon in Tibet.

The British Columbia and Seattle events were aimed, according to Dolma, to raise awareness on how this is a planetary crisis. “And whatever happens on the Tibetan Plateau and in the rest of Asia will impact all of our livelihoods around the world,” she said.

Photo Friday: Nelly Elagina’s View of Mount Elbrus

Among the Caucasus Mountains, on the edge of Russia’s border with Georgia, sits the perennially snow-covered peak of Mount Elbrus, rising to a height of 5,642 meters and holding the title of tallest summit on the European continent. It is home to not one, but two summits, both of which are dormant volcanic domes, and 22 glaciers that feed three different rivers: the Baksan, Kuban, and Malka. The area of its glaciers decreased 14.8 percent during the first half of the 20th century and 6.28 percent during the second half, according to a report by the Russian Academy of Sciences National Geophysical Committee.

Despite its gradually melting glaciers, Mount Elbrus is frequented by climbers because of its status as one of the Seven Summits. The Seven Summits are the highest mountains on each of the seven continents and some serious climbers set out to summit them all. As such, it is a popular destination, but also a rather perilous one: 15-30 climbers die each year seeking to reach the summit, sometimes due to the region’s unpredictable weather.

The stunning wisps of clouds looping around the dark rock formations that peek out of their snowy coverings and the expansive views that can be seen from the mountain are captured by photographer Nelly Elagina. Her images convey a feeling of wonder and excitement that may explain why climbers are drawn to Mount Elbrus. Elagina is a researcher in the department of glaciology at the Russian Academy of Sciences’ Institute of Geography.

All images were taken by Nelly Elagina. You can find her on Instagram here.
