Swiss Glacier Collapse That Buried Village Likely a 'Direct Result of Our Warming Climate'
"What happened to Birch Glacier is what we would expect from rising temperatures in the Alps and elsewhere," one scientist said.
May 29, 2025
Thawing permafrost exacerbated by human-caused global heating is the likely culprit behind a massive glacier collapse that buried nearly the entire Swiss town of Blatten, one scientist said Thursday while warning of the likelihood of similar disasters in the future.
The alpine hamlet of 300 inhabitants—who were evacuated earlier amid warning signs of disaster—was almost completely wiped out on Wednesday after the Birch Glacier, located in the Lötschental Valley in northern Switzerland, collapsed. The glacial avalanche, laden with boulders and other debris, cascaded down the mountainside and into the village, obliterating everything in its path. Local officials said around 90% of Blatten was buried.
"We've lost our village," Blatten Mayor Matthias Bellwald told reporters. "The village is under rubble. We will rebuild."

While there are no verified casualties from the disaster, one 64-year-old man has been reported missing.
Mathieu Morlighem, a glaciologist at Dartmouth College in New Hampshire, told ABC News that permafrost thaw under and along the sidewalls surrounding the glacier likely caused the collapse.
"What happened to Birch Glacier is what we would expect from rising temperatures in the Alps and elsewhere," he explained. "I think we can expect more events like this in the future."
As ABC News reported:
Glaciers in Switzerland have lost almost 40% of their volume since 2000, and the loss is accelerating, according to the Swiss Federal Institute for Forest, Snow, and Landscape Research. Record-high summer temperatures in 2022 and 2023 caused a 10% glacial ice loss in the country.
Experts warn that Switzerland's glaciers could disappear completely by 2100 due to the climate emergency.
As Common Dreams reported in March, the crisis is planetary and is predicted to adversely affect nearly 2 billion people who depend upon glaciers for agricultural irrigation and drinking water.
"Most of the world's glaciers, including those in mountains, are melting at an accelerated rate worldwide," a United Nations Educational, Scientific, and Cultural Organization report published earlier this year warned. "Combined with accelerating permafrost thaw, declining snow cover, and more erratic snowfall patterns... this will have significant and irreversible impacts on local, regional, and global hydrology, including water availability."
The Swiss collapse happened a day before Thursday's opening of the
High-Level International Conference on Glaciers' Preservation in Tajikistan, which aims to "highlight the vital role of glaciers in maintaining global ecological balance and addressing water-related challenges."

German Court Tosses Farmer's Case But Climate Groups Cheer 'Remarkable Precedent'
"This historic judgment lays the next building block in corporate climate accountability," said Jasper Tuelings of the Climate Litigation Network.
May 28, 2025
After a decade of legal proceedings, a German court on Wednesday dismissed a Peruvian farmer's case against energy giant RWE, but both he and green groups still hailed what they called a "landmark ruling" that launched a "new era of accountability" by "setting a powerful precedent."
The farmer, 44-year-old Saúl Luciano Lliuya, grows barley, corn, potatoes, and wheat outside Huaraz, Peru. In 2015, he sued RWE—one of Europe's biggest climate polluters—in Essen, Germany, where the company is headquartered. Although the German utility doesn't operate in Luciano Lliuya's country, he argued that its emissions contributed to the melting of Andean glaciers.
"He said that as a result, Lake Palcacocha—which is located above the city—now has four times as much water than in 2003 and that residents like him were at risk of flooding, especially if blocks of ice were to break off from Palcacocha glacier and fall into the lake, causing it to overflow," according to the BBC. The farmer sought around €17,000, or $19,000, from RWE toward a $3.5 million project to protect Huaraz.
As Reuters reported Wednesday:
Presiding judge Rolf Meyer, at the court in the western city of Hamm, said experts' estimate of the 30-year damage risk to the plaintiff's house of 1% was not enough to take the case further.
Had there been a larger adverse effect, a polluter could have been made to slash emissions or pay damages, Meyer said.
Meyer said the plaintiff's case was argued coherently and that it was "like a microcosm of the world's problems between people of the southern and the northern hemisphere, between the poor and the rich."
"Today the mountains have won," Luciano Lliuya said in a Wednesday statement. "Even if my case doesn't go any further, it has reached an important milestone, and that makes me proud. This ruling shows that the big polluters driving the climate can finally be held legally responsible for the harm they have caused."
"I am, of course, disappointed that the court reached a different conclusion from the glacier scientists who have studied this region for decades and believe my home is at risk," he continued. "We won't receive support from RWE to protect us from the flood risk. But this case was never just about me. It was about all the people who, like us in Huaraz, are already living with the consequences of a crisis we did not create. This ruling opens the door for others to demand justice."
The farmer's lawyer, Roda Verheyen, also framed the decision as a major step forward, saying that "today's ruling is a milestone and will give a tailwind to climate lawsuits against fossil fuel companies, and thus to the move away from fossil fuels worldwide. The plaintiff is grateful to the German courts for the seriousness with which his case was treated."
Other advocates and experts similarly weighed in. Ecojustice climate director Charlie Hatt declared that "this is a historic moment for climate litigation," while University of Oxford professor Thom Wetzer said that "this decadelong case has borne fruit," setting "a remarkable precedent that could enable future cases."
Jasper Tuelings, a strategic adviser with Climate Litigation Network, said that "this historic judgment lays the next building block in corporate climate accountability. Last year's Shell ruling showed us that big polluters have a legal obligation to reduce their future emissions in line with the Paris agreement—today's ruling affirms that these companies can be held accountable for their past emissions too."
The era of major polluters not having to pay for the environmental harms they cause is over. The case between Saul, a Peruvian farmer, and RWE, an energy giant, has shifted the landscape of climate justice. There are over 40 similar ongoing cases. Accountability is coming #SaulvsRWE

RWE, meanwhile, said in a statement that "the decision of the Hamm Higher Regional Court means that the attempt, supported by German NGOs, to use Mr Luciano Lliuya's lawsuit to create a precedent for holding individual companies responsible for the effects of climate change worldwide under German law has failed."
"RWE has always considered such civil 'climate liability' to be inadmissible under German law," RWE added, warning of "unforeseeable consequences for Germany as an industrial location," and noting that "other German courts have dismissed similar climate lawsuits—for example against Volkswagen, Mercedes-Benz, and BMW."
Despite the company's comments, climate advocates appeared undeterred. Sebastien Duyck, a senior attorney at the Center for International Environmental Law, said that "Saul's breakthrough opens up a well of opportunities for the more than 40 similar cases ongoing. It makes it more likely that those living at the sharp edge of climate change, such as Saul and his community, can succeed in holding heavy emitters to account for the damage they cause."
Friederike Otto, a senior lecturer at the Grantham Institute for Climate Change and the Environment, highlighted how science has evolved since Luciano Lliuya's case began a decade ago, which could impact ongoing and future legal proceedings.
"The science is absolutely clear... Human-induced climate change is already affecting weather and climate extremes in every region across the globe," Otto said, citing the Intergovernmental Panel on Climate Change. "This includes Saul's city of Huaraz and RWE contributed without any doubt to climate change."
"The precedent that this case has set underlines just how important scientific evidence is in the global fight against climate change," Otto added. "Since the case was filed 10 years ago, scientists have developed a large body of evidence showing how much companies and states can be held responsible for climate disasters. This is therefore a landmark moment for climate justice, ensuring that communities living in constant danger can hold carbon majors to account."

Scientists Warn Major Glaciers Won't 'Survive This Century,' With Grave Impacts for Billions
"Preservation of glaciers is not just an environmental, economic, and societal necessity," said one expert. "It's a matter of survival."
Mar 21, 2025
Scientists on Friday spent the United Nations' World Water Day and first-ever World Day for Glaciers warning about how fossil fuel-driven global warming melts ice across the planet, endangering freshwater resources and causing seas to rise, with implications for ecosystems, economies, and billions of people.
In a Friday statement, World Meteorological Organization Secretary-General Celeste Saulo pointed to a publication that the U.N. agency released earlier this week: "WMO's State of the Global Climate 2024 report confirmed that from 2022-24, we saw the largest three-year loss of glaciers on record."
"Seven of the 10 most negative mass balance years have occurred since 2016," Saulo continued. "Preservation of glaciers is not just an environmental, economic, and societal necessity. It's a matter of survival."
The WMO report was followed by the Friday launch of a 174-page document from the United Nations Educational, Scientific, and Cultural Organization (UNESCO) that stresses how "billions of people depend on the fresh water that flows from increasingly fragile mountain environments."
"As the water towers of the world, mountains are an essential source of fresh water for (irrigated) agriculture, power generation, industry, and large and growing populations—in the mountains and also downstream," the report details. "Generally, due to higher precipitation and lower evaporation, mountains supply more surface runoff per unit area than lowlands, providing 55-60% of global annual freshwater flows."
The document, The United Nations World Water Development Report 2025—Mountains and glaciers: Water towers, notes that "major cities that have been critically dependent on mountain waters include Addis Ababa, Barcelona, Bogotá, Jakarta, Kathmandu, La Paz, Lima, Los Angeles, Melbourne, Mexico City, New Delhi, New York, Quito, Rio de Janeiro, and Tokyo."
"Globally, up to two-thirds of irrigated agriculture may depend on mountain waters," the report states, "while the number of people in lowlands that strongly depend on water from mountains increased worldwide from around 0.6 billion in the 1960s to some 1.8 billion in the 2000s. An additional 1 billion people in the lowlands benefit from supportive mountain runoff contributions."
"Most of the world's glaciers, including those in mountains, are melting at an accelerated rate worldwide," the publication adds. "Combined with accelerating permafrost thaw, declining snow cover, and more erratic snowfall patterns... this will have significant and irreversible impacts on local, regional, and global hydrology, including water availability."
“The 21st of March 2025 is being celebrated as the first-ever World Day for Glaciers. ‘Celebrate’? Yes, we should celebrate glaciers and their crucial role in sustaining life on Earth for future generations,” says @iceblogger.bsky.social. Great stats here on the importance of glaciers 🧊

The UNESCO publication follows the international Glacier Mass Balance Intercomparison Exercise (GlaMBIE) team's study, published in the journal Nature last month, showing that glaciers have lost an average of 273 billion metric tons of ice annually since 2000.
That figure "amounts to what the entire global population consumes in 30 years, assuming three liters per person and day," Michael Zemp, a professor at Switzerland's University of Zurich and director of the World Glacier Monitoring Service who co-led the GlaMBIE study, explained at the time.
Zemp pointed to that finding and others on Friday, noting that from 2000-23, glacier melt caused global seas to rise 18 mm or about 0.7 inches. He said, "This might not sound much, but it has a big impact: Every millimeter [of] sea-level rise exposes an additional 200,000 to 300,000 people to annual flooding."
In a U.N. video, experts also highlighted parts of the globe that are particularly impacted by melting glaciers. Zemp explained that in "the European Alps, we are one of the regions that is most affected by climate change. Warming is about double the global average, and indeed, glaciers in the Alps are one of the most suffering around the world."
"We have lost, since 2000, almost 40% of the remaining ice. And that means under current melt rates, glaciers will not survive this century in the Alps," he warned.
Today is the first-ever #WorldGlaciersDay!Glaciers provide water for millions of people, regulate sea levels, and support biodiversity.Yet glaciers are disappearing at an alarming rate.#ClimateAction is key to protecting them & supporting those who rely on glaciers.www.un.org/en/observanc...

Scientists are also concerned about the Hindu Kush in the Himalayas, which are often called the "third pole because they hold a lot of water resources," WMO's Sulagna Mishra said in the video. "Here, more than 120 million farmers in the downstream areas are impacted directly because of the melting of the glaciers."
"So, when there are a lot of floods, for example, happening because of melting of glaciers, the livelihoods are changed, people tend to migrate from one place to another," she continued. "So when you ask me how many people are actually impacted, it's really everyone."
As Carbon Brief reported Friday:
Dr. Aditi Mukherji—the director of the climate change, adaptation, and mitigation impact action platform of the CGIAR—tells Carbon Brief that the report is an important call for more "adaptation efforts and funding."
She says that mountain-dwelling communities are "already quite vulnerable due to their remote location and other developmental deficits" and are "increasingly losing their way of life due to no fault of theirs."
However, in some parts of the world, especially the United States, such calls face the pro-fossil fuel agenda of polluting companies and right-wing policymakers that are working to quash the movement for a just transition to clean energy by any means necessary.

'Grim News for the Planet' as Arctic Sea Ice Hits Record Low
"The environment does not care about politics. Keep spewing greenhouse gases and face the consequences."
Mar 06, 2025
European Union officials said the Copernicus Climate Change Service had issued its latest "stark reminder of why climate action is urgent" when the bloc's program announced that it observed less sea ice covering the Earth's oceans last month than at any other point in recorded history.
In the Arctic, sea ice reached its lowest monthly extent on record, at 8% below average, in early February, and it remained below the previous record for the rest of the month.
The oceans were missing an area of ice roughly the size of the United Kingdom last month, according to Copernicus (C3S), and the finding was not an anomaly in recent sea ice observations.
February marked the third consecutive month in which record low sea ice levels for the corresponding month were observed in the Arctic.
C3S reported that in the Antarctic, sea ice levels have rapidly declined in 2025 after appearing to recover to near-record levels in December 2024.
Last month, sea ice near the South Pole reached its fourth-lowest monthly extent, at 26% below average.
C3S said the daily sea ice extent in the Antarctic may have also reached its annual minimum toward the end of the month, which will be confirmed later in March; if confirmed, it would be the second-lowest annual minimum in the satellite record.
"February 2025 continues the streak of record or near-record temperatures observed throughout the last two years," said Samanatha Burgess, strategic lead for climate at the European Center for Medium-Range Weather Forecasts. "One of the consequences of a warmer world is melting sea ice, and the record or near-record low sea ice cover at both poles has pushed global sea ice cover to an all-time minimum."
The melting sea ice was recorded as global average temperatures rose 1.59°C (2.8°F) above the pre-industrial average last month, making it the third-warmest February on record.
In Europe, the temperatures that most exceeded averages were recorded last month in parts of Scandinavia, Iceland, and the Alps. Outside of Europe, "temperatures were most above average over large parts of the Arctic."
The low extent of sea ice will lead to "more solar heat absorbed by the darker oceans," and "faster warming," said Simon Oldridge, a climate campaigner.
The loss of sea ice can also lead to the collapse of ocean currents that are crucial for marine life to thrive.
C3S reported on the record-low sea ice levels as campaigners in the U.S. and around the world condemned recent anti-climate actions taken by U.S. President Donald Trump and the Republican Party, including the country's exit from the Paris climate agreement, the GOP's passing of a bill to end a federal program aimed at reducing planet-heating methane emissions, and Trump's push to fast-track fossil fuel projects—as scientists warn that new extractive projects have no place on a pathway to limiting planetary heating and avoiding its worst impacts.
"The environment does not care about politics," said public health expert Ali Khan. "Keep spewing greenhouse gases and face the consequences."

Study Shows Glaciers Have Lost '3 Olympic Swimming Pools Per Second' Since 2000
One researcher said the findings support calls "for urgent and concrete actions to reduce greenhouse gas emissions and associated warming."
Feb 20, 2025
An international science project on Wednesday published a study in the journal Nature showing that glaciers have lost an average of 273 billion metric tons of ice annually since 2000—depleting freshwater resources, driving sea-level rise, and underscoring the need for sweeping global action to significantly reduce planet-heating pollution.
The Glacier Mass Balance Intercomparison Exercise (GlaMBIE) team compiled major studies to estimate global mass change from 2000, when glaciers—excluding Antarctica and Greenland's ice sheets—held about 121,728 billion metric tons of ice, to 2023.
The researchers found that during that period, the world lost 5% of all glacier ice, with regional losses for the full two decades ranging from 2% on the Antarctic and Subantarctic islands, to 39% in Central Europe.
That's a loss of 6,542 billion metric tons total or 273 billion metric tons per year, "the equivalent of three Olympic swimming pools per second," noted France's National Center for Scientific Research (CNRS).
Glaciologist Michael Zemp, who co-led the study, said in a statement that the annual figure "amounts to what the entire global population consumes in 30 years, assuming three liters per person and day."
"Every tenth of a degree warming that we avoid saves us money, saves us lives, saves us problems."
Although the researchers highlighted the annual average, they also emphasized that the rate of glacier ice loss "increased significantly" from 231 billion metric tons annually during the first half of the study period to 314 billion metric tons per year in the second half. In other words, the amount of ice being lost surged by 36% between the two ranges.
Zemp, a professor at Switzerland's University of Zurich and director of the World Glacier Monitoring Service, told Agence France-Presse that the findings are "shocking" and warned that many smaller glaciers "will not survive the present century."
Stephen Plummer, an Earth observation applications scientist at the European Space Agency, said that "these findings are not only crucial for advancing our scientific understanding of global glacier changes, but also provide a valuable baseline to help regions address the challenges of managing scarce freshwater resources and contribute to developing effective mitigation strategies to combat rising sea level."
The ice loss over the GlaMBIE study's full timeline led to about 18 mm or 0.7 inches of sea-level rise. The researchers projected future losses that lead to 32-67 mm, or 1.26-2.6 inches, of sea-level rise by 2040.
"We are facing higher sea-level rise until the end of this century than expected before," Zemp told AFP, referring to the latest projection from the United Nations Intergovernmental Panel on Climate Change (IPCC).
"You have to reduce the greenhouse gas emissions, it is as simple and as complicated as that," Zemp said. "Every tenth of a degree warming that we avoid saves us money, saves us lives, saves us problems."
The GlaMBIE project manager, Samuel Nussbaumer, similarly told Oceanographic that "our observations and recent modeling studies indicate that glacier mass loss will continue and possibly accelerate until the end of this century," which underpins the IPCC's "call for urgent and concrete actions to reduce greenhouse gas emissions and associated warming to limit the impact of glacier wastage on local geohazards, regional freshwater availability, and global sea-level rise."
The team's findings were released during the U.N.'s International Year of Glaciers' Preservation and the Decade of Action for Cryospheric Sciences—and they "will feed into the next IPCC report, due in 2029," according to CNRS.
Scientists from around the world who were not involved with the study were alarmed by its revelations—which come after the hottest year in human history and amid humanity's failure to curb planet-heating emissions, largely from fossil fuels.
Martin Siegert, a professor at the United Kingdom's University of Exeter, said in a statement that "this research is concerning to us, because it predicts further glacier loss, which can be considered like a 'canary in the coal mine' for ice sheet reaction to global warming and far more sea-level rise this century and beyond. The IPCC indicates 0.5-1 meters this century—but that is with a 66% certainty—hence 1/3 chance it could be higher under 'strong' warming, which unfortunately is the pathway we are on presently."
Andrew Shepherd, a professor at Northumbria University, another U.K. institution, explained that "glacier melting has two main impacts; it causes sea-level rise and it disrupts the water supply in rivers that are fed by meltwater."
"Around 2 billion people depend on meltwater from glaciers and so their retreat is a big problem for society—it's not just that we are losing them from our landscape, they are an important part of our daily lives," he said. "Even small amounts of sea-level rise matter because it leads to more frequent coastal flooding. Every centimeter of sea-level rise exposes another 2 million people to annual flooding somewhere on our planet."

Global Water Woes the 'Canary in the Coal Mine' for Climate Calamity: WMO
"As a result of rising temperatures, the hydrological cycle has accelerated. It has also become more erratic and unpredictable, and we are facing growing problems of either too much or too little water," the WMO lead said.
Oct 07, 2024
The climate crisis is destabilizing the world's water cycle, depriving millions of people of the freshwater resources they need while inundating others with deadly and catastrophic floods.
That's the picture painted by the World Meteorological Organization (WMO)'s third-ever State of Global Water Resources report, released on Monday, which found that 2023 was the driest year for the world's rivers in more than three decades.
"Water is the canary in the coalmine of climate change," WMO Secretary-General Celeste Saulo said in a statement. "We receive distress signals in the form of increasingly extreme rainfall, floods, and droughts which wreak a heavy toll on lives, ecosystems, and economies."
A total of 3.6 billion people struggle to access sufficient water for at least one month per year, according to U.N. Water, and this number is projected to swell to over 5 billion by 2050. In 2023, which was also the hottest year on record, river catchment areas around the world were at their driest in 33 years. As in the two years before, more than half of all catchment areas saw abnormal conditions, with most of them seeing below-average water flow.
Especially hard-hit river systems included the Mississippi and Amazon basins, which shrank to record-low water levels, as well as riparian systems in much of Northern, Central, and South America. Argentina's GDP shrank by 3% due to drought, the WMO found. Meanwhile, the report showed how major river systems in Asia—the Ganges, Brahmaputra, and Mekong river basins—were drier than usual across almost all of their reach.
Another threat to freshwater access is the melting of glaciers. In 2023, the world's glaciers lost their greatest amount of mass in 50 years at over 600 metric gigatons of water. This ice loss was primarily driven by melting in western North America and Europe's Alps. Switzerland's glaciers shrank by 10% in two years.
"It was either too dry or too wet—and neither is encouraging."
"The worldwide loss of glacier volume, equivalent to 600 gigatons of water according to the latest WMO report, is alarming," said report contributor Robert Reinecke of Johannes Gutenberg University Mainz. "It is the greatest loss we have witnessed in the past five decades."
Saulo added: "Melting ice and glaciers threaten long-term water security for many millions of people. And yet we are not taking the necessary urgent action."
While 2023 saw drought and ice melt, its high temperatures combined with the shift from La Niña to El Niño halfway through and the positive phase of the Indian Ocean Dipole also fueled extreme precipitation events.
"It was either too dry or too wet—and neither is encouraging," Reinecke said. "We have to expect both extremes more frequently as global temperatures continue to rise."
Africa saw the deadliest flooding, with Storm Daniel causing a dam collapse in Libya that killed more than 11,000 people in September 2023. Also hard hit were the Greater Horn of Africa, Congo, Rwanda, Mozambique, and Malawi.
"As a result of rising temperatures, the hydrological cycle has accelerated," Saulo said. "It has also become more erratic and unpredictable, and we are facing growing problems of either too much or too little water. A warmer atmosphere holds more moisture which is conducive to heavy rainfall. More rapid evaporation and drying of soils worsen drought conditions."
To respond to these shifting conditions, WMO urged more monitoring and data sharing and said that the Early Warnings for All initiative must cover water-related hazards.
"Far too little is known about the true state of the world's freshwater resources," Saulo said. "We cannot manage what we do not measure. This report seeks to contribute to improved monitoring, data-sharing, cross-border collaboration, and assessments."
In response to the report, water advocate Mina Guli also called for increased conservation efforts.
"To tackle this crisis, we must invest more resources into protecting and restoring our freshwater ecosystems. Healthy rivers, lakes, and wetlands do so much more than provide water—they are our best defense against the worsening impacts of climate change and play a crucial role in ensuring food and water security while also reversing nature loss," Guli wrote on social media.

Researchers Warn of Imminent 'Death Spiral' for Rapidly Melting Alaska Ice Field
The Juneau ice field is melting at a rate of 50,000 gallons per second and is possibly heading "beyond a dynamic tipping point," a new study says.
Jul 02, 2024
The melting of Alaska's Juneau ice field—which contains more than 1,000 glaciers—is accelerating and could reach a tipping point much sooner than predicted, according to research published Tuesday.
The study, which was published in the journal Nature Communications, shows that ice loss from the Juneau ice field began accelerating rapidly after 2005.
The paper's authors found that "rates of area shrinkage were five times faster from 2015-2019 than from 1979-1990," while glacier volume loss—which had remained relatively consistent from 1770-1979—doubled after 2010.
"Forty years from now, what is it going to look like? I do think by then the Juneau ice field will be past the tipping point."
"Thinning has become pervasive across the icefield plateau since 2005, accompanied by glacier recession and fragmentation," the study states. "As glacier thinning on the plateau continues, a mass balance-elevation feedback is likely to inhibit future glacier regrowth, potentially pushing glaciers beyond a dynamic tipping point."
Study lead author Bethan Davies, a glaciologist at Newcastle University in England, said in a statement, "It's incredibly worrying that our research found a rapid acceleration since the early 21st century in the rate of glacier loss across the Juneau ice field."
"Alaskan icefields—which are predominantly flat, plateau icefields—are particularly vulnerable to accelerated melt as the climate warms since ice loss happens across the whole surface, meaning a much greater area is affected," Davies continued. "Additionally, flatter ice caps and icefields cannot retreat to higher elevations and find a new equilibrium."
"As glacier thinning on the Juneau plateau continues and ice retreats to lower levels and warmer air, the feedback processes this sets in motion is likely to prevent future glacier regrowth, potentially pushing glaciers beyond a tipping point into irreversible recession," she added.
Study co-author Mauri Pelto, a professor of environmental science at Nichols College in Massachusetts, told The Associated Press that the Juneau ice field is melting at a rate of about 50,000 gallons per second.
"When you go there the changes from year to year are so dramatic that it just hits you over the head," Pelto said. "In 1981, it wasn't too hard to get on and off the glaciers. You just hike up and you could you could ski to the bottom or hike right off the end of these glaciers. But now they've got lakes on the edges from melted snow and crevasses opening up that makes it difficult to ski."
As the AP reported:
Only four Juneau ice field glaciers melted out of existence between 1948 and 2005. But 64 of them disappeared between 2005 and 2019, the study said. Many of the glaciers were too small to name, but one larger one, Antler glacier, "is totally gone," Pelto said.
Alaska climatologist Brian Brettschneider, who was not part of the study, said the acceleration is most concerning, warning of "a death spiral" for the thinning ice field.
Pelto said that "the tipping point is when that snow line goes above your entire ice field, ice sheet, ice glacier, whichever one."
"And so for the Juneau ice field, 2019, 2018, showed that you are not that far away from that tipping point," he added. "We're 40 years from when I first saw the glacier. And so, 40 years from now, what is it going to look like? I do think by then the Juneau ice field will be past the tipping point."
It's not just Alaska. Glaciers around the world—from Greenland to Switzerland to Africa and the Himalayas—are melting at an alarming rate. The United Nations Educational, Scientific, and Cultural Organization warned in 2022 that glaciers in one-third of the 50 UNESCO World Heritage sites where they are found are on pace to disappear by 2050—even if planet-heating emissions are curbed.
Another study published last year by researchers at Carnegie Mellon University and the University of Alaska found that even if humanity manages to limit planetary heating to 1.5°C above preindustrial temperatures—the more ambitious goal of the Paris agreement—half of Earth's glaciers are expected to melt by the end of the century.

'A Betrayal': Women Elders Rip Swiss Lawmakers' Rejection of Landmark Climate Ruling
"The declaration is an attempt to continue to prevent human rights climate protection for political reasons, rather than recognizing that climate change is a scientific reality that affects everyone," said Greenpeace Switzerland.
Jun 13, 2024
Swiss women elders who recently won a landmark climate case said that they feel betrayed by their federal lawmakers, who voted Wednesday to disregard the court ruling.
The European Court of Human Rights (ECtHR) ruled in April that the Swiss government violated senior citizens' human rights by refusing to heed scientists' climate warnings and swiftly phase out fossil fuel production.
However, on Wednesday the National Council—Switzerland's lower legislative chamber—voted 111-72 to essentially ignore the court's decision, which some lawmakers condemned as judicial overreach. This followed a 31-11 vote by the Council of States, the upper legislative chamber, on a similar measure earlier this month.
"Climate and health are intrinsically linked; good health and a safe climate go hand in hand."
"We are appalled by this decision which feels like both a betrayal of older women but is also out of step with humankind's collective responsibility to tackle climate change for the benefits of vulnerable groups and the future of all humankind," said Pia Hollenstein, a retired nurse and member of KlimaSeniorinnen, the group of women ages 64 and older who sued their government for failing to take adequate action to stop the planet from heating 1.5°C, the more ambitious target of the Paris agreement.
"As a nurse, I have seen how climate and health are intrinsically linked; good health and a safe climate go hand in hand," she added.
Responding to Wednesday's vote, Greenpeace Switzerland said that "the declaration is an attempt to continue to prevent human rights climate protection for political reasons, rather than recognizing that climate change is a scientific reality that affects everyone."
Switzerland's Alpine climate is particularly vulnerable the effects of global heating, which is mainly caused by burning fossil fuels. Studies have shown that the country's glaciers—a key water source for millions of Europeans—could disappear by the end of the century if warming isn't curbed.
At least one lawmaker who voted to flout the ECtHR ruling attacked KlimaSeniorinnen members. Jean-Luc Addor of the right-wing Swiss People's Party dismissed the activists as "just a bunch of... 'boomeuses',"—or female Baby Boomers—"who are trying to deny our children the living conditions they have enjoyed all their lives."
However, Véronique Boillet, a member of the Swiss Human Rights Institute and a law professor at the University of Lausanne, said in a statement: "The binding nature of the rulings of the European Court of Human Rights is the heart of the European human rights system. It is the element that makes this system unique and a model worldwide."
"It is not for the Swiss Parliament to decide when a judgment has been implemented and when further measures are necessary," she continued. "It is normal that courts set certain objectives, as the ECtHR did for Swiss politics. It is also a sign of a functioning system of checks and balances."

'Sirens Are Blaring': WMO Says 2023 Shattered Key Climate Metrics
"Fossil fuel pollution is sending climate chaos off the charts," U.N. Secretary-General António Guterres said.
Mar 19, 2024
Last year broke records for several key climate indicators, including surface temperatures, ocean heat, sea-level rise, and the loss of Antarctic sea ice, the World Meteorological Organization found in its State of the Global Climate 2023 report, released Tuesday.
The agency confirmed that 2023 was the hottest year on record and said it gave an "ominous" new meaning to the phrase "off the charts."
"Earth is issuing a distress call," United Nations Secretary-General António Guterres said in a video statement. "The latest State of the Global Climate report shows a planet on the brink. Fossil fuel pollution is sending climate chaos off the charts. Sirens are blaring across all major indicators."
"The climate crisis is THE defining challenge that humanity faces and is closely intertwined with the inequality crisis."
2023 saw an average global near-surface temperature of 1.45°C, the report found, making 2023 the hottest on record and the cap on the warmest 10-year period on record.
"Never have we been so close—albeit on a temporary basis at the moment—to the 1.5°C lower limit of the Paris agreement on climate change," WMO Secretary-General Celeste Saulo said in a statement. "The WMO community is sounding the red alert to the world."
The European Union's Copernicus Climate Change Service and European Center for Medium-Range Weather Forecasts had found separately that January 2024 capped a 12-month period that exceeded the 1.5°C target for the first time.
2023 was also a particularly alarming year for ocean heat, with nearly a third of the ocean in the midst of a marine heatwave at any time during the year. Global sea-surface temperatures reached record heights for April and every month after, with July, August, and September especially hot. Ocean heat content also broke records, and more than 90% of the ocean experienced a heatwave for at least a portion of the year.
The world's glaciers and sea ice did not fare any better. Glaciers lost the most ice in any year since record-keeping began in 1950, and Antarctica's sea-ice extent at the end of winter smashed the previous record by 1 million square kilometers.
"Because of burning fossil fuels, which leads to CO2-induced global heating, we have impacted the polar regions to such a degree that 2023 saw by far the greatest loss of sea ice in the Antarctic and of land ice in Greenland," University of Exeter polar expert Martin Siegert told Common Dreams. "The world will feel the detrimental effects now and into the future because the changes observed will lead to 'feedback' processes encouraging further change."
"Our only response must be to stop burning fossil fuels so that the damage can be limited," Siegert added. "That is our best and only option."
2023 also saw record sea-level rise and ocean acidification.
"Climate change is about much more than temperatures," Saulo said. "What we witnessed in 2023, especially with the unprecedented ocean warmth, glacier retreat, and Antarctic sea ice loss, is cause for particular concern."
Records were broken too for the main cause of all this warming and melting—the levels of greenhouse gasses in the atmosphere. Carbon dioxide, methane, and nitrous oxide all reached record levels in 2022, and data indicates that the atmospheric concentrations of all three continued to rise in 2023, with carbon dioxide levels 50% higher than before the industrial revolution.
The report also considered the impacts of global heating on extreme weather events: 2023 saw several especially devastating climate-fueled disasters, including lethal flooding from Cyclone Daniel in Libya; Tropical Cyclone Mocha, which displaced 1.7 million people in the region around the Bay of Bengal; an extreme heatwave in southern Europe and North Africa; a record wildfire season in Canada that smothered several North American cities in heavy smoke; and the deadliest U.S. wildfire in more than 100 years in Hawaii.
In addition to claiming lives and forcing people from their homes, these disasters have several other impacts on peoples' well-being. For example, the report noted that the number of people suffering from acute food insecurity had shot up to 333 million in 2023, more than two times the 149 million before the pandemic. While the root causes of this are war and conflict, economic downturns, and high food prices, extreme weather events can make the situation worse. When Cyclone Freddy, one of the longest-lasting cyclones ever, struck Madagascar, Mozambique, and Malawi in February, it flooded vast swaths of agricultural fields and damaged crops in other ways.
"The climate crisis is THE defining challenge that humanity faces and is closely intertwined with the inequality crisis—as witnessed by growing food insecurity and population displacement, and biodiversity loss," Saulo said.
Guterres, meanwhile, said the impact of extreme weather on sustainable development was "devastating."
"Every fraction of a degree of global heating impacts the future of life on Earth," he said.
There was some positive news in the report, mainly that renewable energy increased new capacity by nearly 50% in 2023 compared with 2022, the highest rate of increase in 20 years. Global climate finance nearly doubled from 2019-2020 to almost $1.3 trillion, but this was still only 1% of global gross domestic product.
To have a shot at limiting warming to 1.5°C, finance needs to increase by nearly $9 trillion by 2030 and another $10 trillion by 2050, but this is much lower than the estimated cost of doing nothing, which would be $1,266 trillion from 2025-2100, though the WMO said this was likely a "dramatic underestimate."
Guterres said it was still possible to limit long-term global temperature rise to 1.5°C, but it required swift action; leadership from the G20 nations toward a just energy transition; countries proposing 1.5°C-compliant climate plans by 2025; increased climate finance flows toward the developing world, including for adaptation and Loss and Damage; universal coverage by early warning systems by 2027; and "accelerating the inevitable end of the fossil fuel age."
"There's still time to throw out a lifeline to people and planet," Guterres said, "but leaders must step up and act now."

'Frightening': Greenland Losing 33 Million Tons of Ice Per Hour Due to Climate Crisis
A new study finds the island's ice sheet is retreating 20% more than previously thought.
Jan 17, 2024
New research on the rate at which Greenland's glaciers are melting shed new light on how the climate emergency is rapidly raising the chance that crucial ocean current systems could soon collapse, as scientists revealed Wednesday that the vast island has lost about 20% more ice than previously understood.
Scientists at the National Aeronautics and Space Agency (NASA) Jet Propulsion Laboratory led the study, published in Nature, which showed that Greenland's ice cap is losing an average of 33 million tons of ice per hour, including from glaciers that are already below sea level.
The researchers analyzed satellite photos showing the end positions of Greenland's glaciers every month from 1985 to 2022, examining a total of about 235,000 end positions.
Over the 38-year period, Greenland lost about 1,930 square miles of ice—equivalent to one trillion metric tons and roughly the size of Delaware.
An earlier study had estimated that 221 billion metric tons had been lost since 2003, but the researchers added another 43 billion metric tons to that assessment.
Previous research had not quantified the level of ice melt and breakage from the ends of glaciers around the perimeter of Greenland.
"Almost every glacier in Greenland is retreating. And that story is true no matter where you look," Chad Greene, a glaciologist at the NASA Jet Propulsion Laboratory who led study, told The New York Times. "This retreat is happening everywhere and all at once."
Because the glaciers examined in the study are already below sea level, their lost ice would have been replaced by sea water and would not have contributed to sea-level rise.
But as Greene told The Guardian, "It almost certainly has an indirect effect, by allowing glaciers to speed up."
"These narrow fjords are the bottleneck, so if you start carving away at the edges of the ice, it's like removing the plug in the drain," he said.
The previously unaccounted-for ice melt is also an additional source of freshwater that pours into the North Atlantic Ocean, which scientists warn places the Atlantic Meridional Overturning Circulation (AMOC) at risk of collapse.
AMOC carries warm water from the tropics into the North Atlantic, allowing nutrients to rise from the bottom of the ocean and supporting phytoplankton production and the basis of the global food chain.
A collapse of the system would also disrupt weather patterns across the globe, likely leading to drier conditions and threatening food security in Asia, South America, and Africa, and increasing extreme weather events in other parts of the world.
One analysis found the collapse could take place as soon as 2025.
Charlie Angus, a member of the Canadian Parliament representing the New Democratic Party, noted that the study was released as Canada's government continues to support fossil fuel production and what experts call false solutions to the planetary heating crisis—including a $12 billion carbon capture and storage project led by tar sands oil companies.
The Environmental Voter Project in the U.S. urged Americans to consider the latest statistics on melting glaciers when choosing the candidates and political parties they will support in 2024.
"Greenland is losing 30 million tons of ice an hour," said the group. "So vote like it."
