Swiss Glacier Collapse Engulfs Alpine Village in Rock and Ice
(Bloomberg) -- A Swiss glacier has collapsed, destroying most of the Alpine village of Blatten in a wave of rock and ice.
Live footage on Wednesday shows 3 million cubic meters of rock and mud burying Blatten and the nearby Lonza river. That's potentially increasing threats should the flow of water be blocked, according to the cantonal government in Valais.
'The worst-case scenario has become a reality,' Raphaël Mayoraz, head of the natural dangers service for Valais, told reporters on Wednesday 'It's an extremely rare phenomenon.'
About 300 people were evacuated from the village in the southern Loetschental valley 10 days ago as the risk of a rupture to the Birch glacier mounted. The army has been deployed to help with recovery efforts, with one person missing, according to Associated Press.
Scientists have long warned that a warming planet is making such events more likely. The Alps have warmed about 2C since the pre-industrial period, with many glaciers losing half their mass since 1900. Three years ago, 11 people were killed after a glacial ice shelf collapsed in the Dolomites in Italy following record-high temperatures.
Swiss researchers have explicitly sounded the alarm over the rate of thaw, which appears to be accelerating.
The world is currently on track to overshoot the critical warming threshold of 1.5C, with some estimates pointing to an average temperature rise of twice that by the end of the century. Exceeding 1.5C of warming will have irreversible consequences for glacier mass, scientists warned in a recent study, underscoring the need to slash greenhouse has emissions.

Climate change could double summer rainfall in the Alps: Study
Climate change could double summer rainfall in the Alps (Picture credit: AFP) GENEVA: Short, intense summer rainfall in Alpine regions is likely to become more frequent and severe in the future because of global warming , according to a study released Thursday by the University of Lausanne (UNIL). Researchers said that in a scenario where temperatures rise by two degrees Celsius (about 3.6 degrees Fahrenheit), the Alps and nearby regions could experience episodes of intense summer rainfall twice as often as currently. "With such warming, an intense storm currently expected once every 50 years could occur once every 25 years in the future," said the Swiss university, which conducted the study in collaboration with the University of Padua in Italy. "Hot air holds more moisture (around seven per cent more per degree), intensifying storm activity", the researchers said. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Free P2,000 GCash eGift UnionBank Credit Card Apply Now Undo "As the Alpine environment warms faster than the global average, it is particularly affected," they added. The study used summer rainfall data collected from nearly 300 meteorological stations across the European Alps in Switzerland, Germany, Austria, France and Italy. They focused on record-breaking rainfall events, lasting from 10 minutes to an hour, that occurred between 1991 and 2020, as well as the temperatures associated with these episodes. "The sudden and massive arrival of large volumes of water can exceed the soil's absorption capacity," which can "trigger flash floods and debris flows, causing damage to infrastructure", said Nadav Peleg, a researcher at UNIL and the study's lead author. Researchers recommend "preparing urban water management systems and other infrastructures" that are ill-suited to handle significant rainfall volumes. "Promptly updating engineering and urban planning standards" would help mitigate potential risks associated with these events, they added, while also emphasising the need to "limit global warming to 1.5°C or less above current levels". According to scientists from the United Nations' IPCC panel on climate change , there is a 50 per cent chance of global temperatures rising by an average of 1.5°C by 2030-2035. "We are already observing a trend towards intensified summer storms and this trend is expected to worsen in the coming years," said Francesco Marra, a researcher at the University of Padova and a co-author of the study.

Satellite Images Show Massive Damage To Iran's Arak Nuclear Facility
New Delhi: Satellite pictures from Maxar Technologies, dated June 19, confirm that Israel's recent airstrike caused substantial structural damage to Iran's heavy water reactor facility at Arak, also known as Khondab, roughly 250 kilometres southwest of Tehran. The high-resolution images reveal the collapse of the upper section of the reactor dome alongside visible destruction to adjacent infrastructure, including distillation towers. While Iranian authorities acknowledged that "projectiles" had struck the compound, they did not initially disclose the extent of the destruction. The satellite images provide the most detailed visual confirmation of the Israeli strike's impact. Facility Designed For Plutonium Production Though not operational at the time of the strike, the Arak facility has remained under close observation by nuclear experts due to its technical capacity to produce plutonium, a material that, like highly enriched uranium, can be used to construct a nuclear weapon. Iran has long maintained that its nuclear programme is for peaceful purposes. Arak was originally conceived in the 1990s following Iran's decision to pursue a nuclear capability in response to the 1980-88 war with Iraq. Unable to procure a heavy water reactor from international sources, Tehran opted to develop its own. According to the Associated Press, heavy water reactors differ from light water reactors in that they use deuterium oxide (heavy water) as a neutron moderator, enabling the use of natural uranium and the production of plutonium as a byproduct. The Israeli Strikes Over the past week, Israel has acknowledged strikes on Natanz, Isfahan, Karaj, and Tehran, describing the campaign as a preemptive measure to degrade Iran's nuclear capabilities and prevent any progress toward weaponisation. Video footage released by the Israel Defense Forces shows precision-guided munitions hitting the reactor dome, followed by a plume of fire and debris. The footage, though brief, was consistent with Maxar's satellite imagery showing the collapse of the reactor dome's crown structure. In a statement, Israeli officials said the attack was "intended to target the plutonium-producing component of the Khondab reactor in order to prevent its restoration and eventual use for military nuclear development." The International Atomic Energy Agency (IAEA), the UN's nuclear watchdog, has confirmed that there was no radiological release from the Arak facility, noting that the reactor was not yet loaded with fuel and had never entered operational status. Nevertheless, the agency expressed "serious concern" over the precedent of military attacks on nuclear installations. Arak's Role In 2015 Nuclear Deal The Arak reactor was a contentious point during the negotiations of the 2015 Joint Comprehensive Plan of Action (JCPOA), the nuclear deal between Iran and six world powers. As part of that agreement, Iran pledged to redesign the reactor to significantly reduce its plutonium output and render part of the core inoperable by pouring concrete into it. Yet, following the US withdrawal from the agreement in 2018 under US President Donald Trump, progress on the redesign halted. In 2019, Ali Akbar Salehi, the head of Iran's Atomic Energy Organisation at the time, revealed on Iranian state television that duplicate parts had been secretly procured to allow for the potential reassembly of the disabled components. Inspectors from the IAEA have repeatedly said since then that due to limitations imposed by Iranian authorities, the agency lost "continuity of knowledge" regarding both the reactor's configuration and heavy water stockpiles.

Scientists Stumble Upon Way to Reduce Cow Dung Methane Emissions
(Bloomberg) -- Twice a day at milking parlors all over New Zealand, the world's biggest dairy exporter, sheds are hosed down to wash away cow dung into large manmade ponds. In an attempt to recycle the water in the lagoons, two local scientists — Keith Cameron and Hong Di — began testing the addition of polyferric sulfate, a chemical that's been widely used in wastewater treatment to separate liquids from solids. The process worked, but that didn't prove to be their most interesting finding. When the pair of soil and physical sciences professors at Lincoln University ran checks to monitor for any impact on greenhouse gas emissions, they made a startling observation: Methane emissions from the wastewater had decreased by more than 90%. 'The whole course of our research program changed overnight,' said Cameron, who has retired from teaching and spent the last four years researching and developing the treatment. Di said manure accounts for roughly 10% of livestock methane emissions, a greenhouse gas that's more than 80 times more potent than carbon dioxide over a 20-year period. Large industrial farms often collect and store waste in giant sealed tanks known as anaerobic digesters that capture methane. Those digesters can cost millions of dollars, though, and curtailing the pollution on smaller farms has remained challenging. But Cameron and Di may have unwittingly found something that works. By introducing polyferric sulfate into the lagoons, the scientists tipped the scale in favor of sulfate-reducing microorganisms, allowing them to outcompete methanogens —which generate methane, are plentiful in cow poop and grow considerably in effluent ponds — for food. The result was a sharp drop in a powerful greenhouse gas that farmers have been trying to tame for years. The innovation — developed under the name EcoPond — is being rolled out across 250 farms associated with Fonterra Co-operative Group and Synlait Milk Ltd. through a pilot program. Dairy giant Fonterra, New Zealand's largest company that's owned and supplied by thousands of farming families, says the treatment can help it toward a goal of cutting on-farm emissions intensity 30% by 2030 compared to 2018 levels. Food systems, which encompass everything from growing and processing food to consuming it or throwing it away, account for about a third of humanity's greenhouse gas emissions. Much of that footprint is linked to livestock farming, a major source of methane. Tackling those emissions has proven difficult because there are few solutions to the biological processes that generate the gas. For example, to address methane released by animals like cows and sheep, scientists are developing burp-catching masks, seaweed-based supplements and vaccines. So far, none of those solutions have had a major impact. Cameron and Di's innovation is part of an emerging field of scientific work that's focused on cutting the emissions from manure. The methane captured by digesters used on some large farms can then be used to generate heat, electricity or fuel. But in New Zealand, where livestock spend most of their time at pasture and herd sizes are smaller, the amount of manure generated indoors typically isn't enough to warrant a digester. To treat a lagoon full of cow poop, the mixture is sucked into a pump on a truck and run through a manifold where it is mixed with polyferric sulfate and sulfuric acid. After treatment, the slurry is deposited back in the lagoon. The process typically takes a few hours and is repeated every six to eight weeks. Agnition, the unit of farmers collective Ravensdown that's seeking to commercialize the process, is still determining how much it will cost. The group declined to provide estimates. Funding for the Fonterra pilot comes from the collective and through programs backed by Mars Inc. and Nestle SA. 'It's likely to be affordable for farmers, particularly if they're dairy and their cooperative is supporting them to reduce methane,' said Mike Manning, Ravensdown's chief science officer. The treatment has the potential to reduce New Zealand's individual dairy farm emissions by between 7% and 9%, according to Cameron. Agriculture is a cornerstone of the nation's economy and accounts for about 80% of its exports and more than half of its total greenhouse gas emissions. While the initial pilot is focused on farms raising cows, the approach has 'broad applicability across various methanogenic environments — such as rice paddies, wetlands and similar systems,' said Marcelo Mena, chief executive officer at the Global Methane Hub, a nonprofit dedicated to reducing the greenhouse gas, and which isn't involved in the New Zealand project. Mena is also a professor of biochemical engineering at the Pontifical Catholic University of Valparaíso in Chile. One drawback to using polyferric sulfate and other materials to inhibit methanogens in manure is that the approach can impact soil and water quality and disrupt microbial ecosystems, said Zhidan Liu, a professor of agricultural engineering at China Agricultural University in Beijing. There was no significant difference on pasture yield or soil condition over a four-year trial in which Cameron and Di compared effluent treated with polyferric sulfate and untreated plots, according to a 2023 study. The treatment developed by Cameron and Di is a welcome relief for farmers under pressure to reduce their emissions but with limited opportunities to do so, said Stuart Taylor, the general manager of farming at Craigmore, a farming, horticulture and forestry business. 'The New Zealand agricultural community realizes they have a role to play in reducing their greenhouse gases,' said Taylor. 'They've been screaming out for technologies to support them.' --With assistance from Tom Redmond. More stories like this are available on
