The Collapse of the Frozen FoundationMongolia is undergoing a profound geological shift as its cryosphere rapidly evolves, threatening the stability of its unique landscape. While often associated with the Arctic, Mongolia hosts some of the most southerly permafrost landscapes in the northern hemisphere. The rapid warming of the country is causing this invisible foundation to shift, fundamentally altering the physical and ecological processes that have defined the region for centuries.Quantifying the Cryosphere LossThe data reveals a dramatic acceleration in the degradation of the frozen ground. Historical surveys from the 1970s suggested that nearly 63% of Mongolia was underlain by permafrost. However, current estimates indicate that only 26% to 29% remains. Unlike the ice-rich permafrost found in Siberia or Alaska, Mongolia's frozen ground is relatively warm, thin, and dry, making it exceptionally sensitive to rising temperatures.Permafrost Coverage: Declined from 63% (1970s) to 26-29% (current).Climate Sensitivity: Mongolian permafrost is warm, thin, and dry, unlike ice-rich regions in the north.Contributing Factors: Climate change is primary, but overgrazing accelerates thaw by removing vegetation insulation.Infrastructure and Ecosystems Under SiegeThe physical impacts of this thaw are visible in both the built environment and the natural world. In the Darkhad Depression, thermokarst ponds are expanding as underground ice melts, causing ground subsidence and collapsing pingo structures. This instability is not limited to nature; it is compromising human infrastructure. In Bayanzurkh sum, school boarding facilities are suffering from cracked walls and fissures as the ground beneath them shifts.Ecologically, the changes are equally disruptive. Communities are witnessing the migration of wetlands, the shifting of springs, and the unpredictable drying or wetting of traditional grazing pastures. Furthermore, the region is seeing an increase in migratory birds from China, consuming large quantities of fish and altering local freshwater ecosystems.A Warning for the Circumpolar NorthMongolia serves as a critical "natural laboratory" for studying permafrost dynamics due to the diversity of its landscapes. The rapid changes occurring here are not isolated; they affect the entire circumpolar north. As the frozen ground thaws, it releases stored carbon and alters water cycles, signaling a broader shift in global climate stability that will require urgent adaptation strategies for nomadic herders and urban centers alike.

The Arrest That Sparked International ConcernThe operation began at 9am Moscow time, but took place across all of Russia's 11 time zones. Almost simultaneously, agents of the federal security service (FSB) raided the homes and workplaces of 17 Indigenous rights activists. Officers carried out searches, confiscated laptops and phones, and arrested and interrogated activists about participation in international forums. Most were let go; many have since left the country. Others remain in Russia, but will no longer speak up.Six months later, one remains in jail. Daria Egereva, one of Russia's foremost Indigenous rights activists, is accused of membership of a terror group. No trial date has been set. Her supporters say the charges are fabricated and she has been targeted for speaking out.Egereva was not just any activist. A member of the Selkup indigenous group, from western Siberia, she was a "bright star" of Russia's indigenous rights movement. As a member of the UN's Indigenous Peoples' Coordinating Body, she had international status. Weeks before her arrest, she had played a key role at Cop30 in Brazil as co-chair of the Indigenous People's Forum on Climate Change.Her jailing has shone a spotlight on the plight of Russia's Indigenous people, threatened by authoritarianism, extractivism and climate breakdown.The Climate Crisis in Russia's Arctic"They are really seeing the worst effects of climate change," said Alicia Moncada, director of global advocacy at Cultural Survival, which campaigns for Indigenous rights. "They are on the frontline of the frontline – that's why [Egereva's] advocacy was super important."The polar north is heating faster than any other part of the planet. In recent decades, temperatures in Arctic regions have risen three to four times faster than the global average. Communities based on permafrost are seeing their world collapse around them."The elders are saying that nature has stopped trusting us," said one exiled Indigenous leader, who requested that his name be withheld. "The traditional ways of predicting nature are not working any more."Many settlements sit next to the banks of rivers and lakes. Due to the melting permafrost, those banks are beginning to crumble. "There is a real threat of destruction for a lot of those villages," said the leader, who spoke through an interpreter. And the melting ice has brought a new source of tension: newly accessible critical mineral resources.Resource Extraction and Indigenous Displacement"All these resources of the Russian Federation, a majority of them are located under the lands of Indigenous people: gold, diamonds, oil, gas, coal," the leader said. "For some people it is a treasure, but for us it is a curse."Because the companies are coming to our land for those resources and they are pushing us out. Even if they don't push us out, the environmental situation in those places will become so bad that we are unable to hunt or fish."One of the elders said that we can adapt to anything, but we will not be able to survive without our land."The Government Crackdown on Indigenous ActivismAlthough Indigenous groups maintained their identities, by the end of the Soviet era they lacked independent organisation and relied on the state. Egereva had been part of a new generation of leaders who had encouraged community self-empowerment.But this assertiveness brought them into conflict with the authorities. Even before the war in Ukraine, the Russian state claimed that its enemies were exploiting environmental and indigenous issues. Now, with the war a pretext for a crackdown on civil society, Indigenous people are among those at the sharp end.To date, 830 organisations and 20,813 individuals have been put on the "list of terrorists and extremists", according to the UN. Among them was Aborigen Forum, a network of Indigenous defenders designated an "extremist organisation" in July 2024.Russian authorities have based their charges against Egereva and her co-defendant, Natalia Leongardt, a civil rights activist, on their involvement with Aborigen. Authorities claim it is part of an anti-state "post-Russia free nations forum".International Response and Russian DefenseIn a bail hearing on 29 April, Egereva and Leongardt denied being part of any anti-state conspiracy. "I am not familiar with and do not know this organisation," Egereva told the court. "What we are being accused of is completely untrue ... I ask to be allowed to return home and embrace my children."The court refused to grant them bail, remanding them in custody until at least mid-June. The following day, Russia celebrated a new federal holiday: the "Day of Indigenous Small-Numbered Peoples".The Russian embassy told the Guardian: "The investigation concerning Daria Egereva is an internal Russian legal matter, conducted in full accordance with Russian law. As proceedings are ongoing, we are not in a position to comment on the specifics of the case."Russia firmly rejects any allegations of violations of Indigenous people's rights. Unlike a number of western states – including Britain in its former colonies – Russia has no history of forced assimilation of Indigenous communities. Russian law affords Indigenous peoples special legal protections, guaranteeing their collective and individual rights, cultural identity, and linguistic heritage under the constitution and in line with international norms."Russia is actively engaged in the international climate agenda, taking account of both the challenges and the economic opportunities emerging in its northern regions – including expanded access to the northern sea route and mineral resources in permafrost zones. All such projects are carried out with the aim of supporting regional development, creating jobs and attracting investment, including for the benefit of Indigenous communities in these areas."

Argentina's lawmakers have given the green light to a bill championed by President Javier Milei that permits mining in sensitive glacier and permafrost regions. The move has sparked fierce criticism from environmentalists, who argue it jeopardizes vital water sources. The bill, which was already approved by the Senate in February, passed with 137 votes in favor, 111 against, and three abstentions in the Chamber of Deputies after a marathon 12-hour debate. This development is seen as a significant victory for Milei, who has been pushing for looser regulations to attract large-scale mining projects. Environmentalists have expressed deep concerns that the reforms will undermine protections for glaciers and permafrost, which are crucial for water supplies. Thousands of people demonstrated outside parliament, with some protesters clashing with police. Banners displayed slogans such as 'Water is more precious than gold!' and 'A glacier destroyed cannot be restored!' The bill allows for mining of metals like copper, lithium, and silver in the Andes mountains. Argentina is a major producer of lithium, a critical component for the global tech and green energy sectors. The central bank forecasts that mining exports could triple by 2030. Milei, who does not believe in man-made climate change, argues that the bill is necessary for economic growth. 'Environmentalists would rather see us starve than have anything touched,' he has stated. The reform gives provinces more power to decide which areas to protect and which to exploit economically. Environmental activist Flavia Broffoni countered that 'the science is clear' and that creating a 'sustainable mine' in a periglacial environment is not possible. With nearly 17,000 glaciers and rock glaciers in Argentina, concerns over glacial reserves shrinking due to climate change add urgency to the debate.

Argentina's congress has approved a bill promoted by President Javier Milei that authorizes mining in ecologically sensitive areas of glaciers and permafrost, sparking widespread environmental protests. The bill, which was already approved by the senate in February, will make it easier to mine for metals such as copper, lithium, and silver in frozen parts of the Andes mountains.The chamber of deputies approved the amendment with 137 votes in favor, 111 against, and three abstentions after nearly 12 hours of debate. Environmentalists argue that the legislative changes will weaken protections for crucial water sources, with thousands protesting outside parliament, holding banners with slogans such as “Water is more precious than gold!” and “A glacier destroyed cannot be restored!”Seven Greenpeace activists were arrested earlier in the day after scaling a statue outside parliament and unfurling a banner urging lawmakers “not to betray the Argentine people”. The passage of the amendment is a new coup for Milei, who pushed through looser labor laws in February despite repeated street protests.Environmental activists, such as Flavia Broffoni, argue that there is no possibility of creating a 'sustainable mine' in a periglacial environment. Argentina has nearly 17,000 glaciers or rock glaciers, with glacial reserves in the north-west shrinking by 17% in the last decade due to climate change.Milei, a free-market radical who does not believe in human-made climate change, says the bill is necessary to attract large-scale mining projects. The Central Bank of Argentina estimates that the country could triple its mining exports by 2030. Supporters argue that the bill will provide legal certainty and clear definitions, while critics, such as Enrique Viale, warn that it threatens the water supply for 70% of Argentinians.
