Nepal holds tribute for disappearing glacier
KATHMANDU, Nepal (AFP) — Dozens trekked to Nepal's Yala glacier for a ceremony Monday to mark its rapid disappearance due to climate change and put a spotlight on global glacial retreat.
The Yala glacier, located between 5,170 and 5,750 meters above sea level, is in the Langtang Valley in northern Nepal.
Since 1974, the glacier has shrunk in area by 66 percent and retreated 784 meters, according to the International Center for Integrated Mountain Development.
Scientists warn it may eventually disappear by the 2040s if the warming trend continues, and might be among the first in Nepal to join the growing numbers of glaciers declared "dead" worldwide.
"In the 40 years I have studies this glacier, I have seen it halve with my own eyes. We worry that the next generation might not be able to see it," Sharad Prasad Joshi, a cryosphere specialist at ICIMOD, told Agence France-Presse.
Prayer flags fluttered Monday as Buddhist monks performed a ceremony for Yala, with the Himalayas towering behind them.
Two granite plaques were unveiled engraved with memorial messages in Nepali, English and Tibetan.
"This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it," part of the message in one of the plaques read.
The words were by Icelandic writer Andri Snaer Magnason, whose message is also at the site of the world's first glacier funeral in Iceland. Glacier funerals have also been held in Mexico, the United States and Switzerland.
The ceremony comes as the world marked near-record high global temperatures in April, according to the EU's climate monitor.
In its latest bulletin, the Copernicus Climate Change Service said that April was the second-hottest in its dataset, which draws on billions of measurements from satellites, ships, aircraft and weather stations.
All but one of the last 22 months exceeded 1.5 degrees Celsius above pre-industrial levels, the warming limit enshrined in the Paris agreement, beyond which major and lasting climate and environmental changes become more likely.
Time to act
Yala is one of seven glaciers in the 3,500 kilometer-long arc of the Hindu Kush Himalayas to have been monitored annually for a decade or more, according to ICIMOD.
Joshi said that the ceremony was also to honour the glacier as it has been an "open textbook" for young researchers and glaciologists. Himalayan glaciers, providing critical water to nearly two billion people, are melting faster than ever before due to climate change, exposing communities to unpredictable and costly disasters.
Experts say that on current melt rates, many glaciers worldwide will not survive the 21st century.
Last month, the United Nations said that all 19 of the world's glacier regions experienced a net loss of mass in 2024 for the third consecutive year.
Together, they lost 450 billion tonnes of mass, the organization said, citing new data from the Swiss-based World Glacier Monitoring Service.
Maheshwar Dhakal, chief at the Nepal government's climate change management division, said in a statement shared by ICIMOD that Nepal is at the frontlines of the impacts of temperature rise despite minimal emissions.
"We are urging world leaders to pay attention to the changes in mountain glaciers, such as Yala, because our own fate, and futures, is bound up in those of our frozen freshwater reserves," Dhakal said.
"Glacier loss is irreversible on human timescales. The time to act is now."

Webb telescope spots strong 'hints'of life on distant planet
PARIS (AFP) — Astronomers announced Thursday that they had detected the most promising "hints" of potential life on a planet beyond our solar system, though other scientists expressed skepticism. There has been vigorous debate in scientific circles about whether the planet K2-18b, which is 124 light years away in the Leo constellation, could be an ocean world capable of hosting microbial life. Using the James Webb Space Telescope, a British-US team of researchers detected signs of two chemicals in the planet's atmosphere long considered to be "biosignatures" indicating extraterrestrial life. On Earth, the chemicals dimethyl sulfide (DMS) and dimethyl disulfide are produced only by life, mostly microscopic marine algae called phytoplankton. The researchers emphasized caution, saying that more observations were needed to confirm these findings, and that they were not announcing a definitive discovery. But the implications could be huge, according to Nikku Madhusudhan, a Cambridge University astrophysicist and lead author of the study, published in The Astrophysical Journal Letters. "What we are finding at this point are hints of possible biological activity outside the solar system," he told a press conference. "Frankly, I think this is the closest we have come to seeing a feature that we can attribute to life." But outside experts pointed to disputes over previous discoveries about the exoplanet, adding that these chemicals could have been created by unknown means having nothing to do with life. More than eight times the mass of Earth and 2.5 times as big, K2-18b is a rare exoplanet that orbits its star in a habitable or "goldilocks" zone. This means it is neither too hot nor too cold to have liquid water, considered the most important ingredient for life. Telescopes observe such far-off exoplanets when they cross in front of their star, allowing astronomers to analyze how molecules block the light streaming through their atmosphere. In 2023, the Webb telescope detected methane and carbon dioxide in K2-18b's atmosphere, the first time such carbon-based molecules were detected on an exoplanet in a habitable zone. It also detected weak signals of the chemical DMS, leading astronomers to turn Webb towards the planet again a year ago, this time using its mid-infrared instrument to detect different wavelengths of light. They found much stronger signs of the chemicals, though still well below the "five sigma" threshold of statistical significance scientists seek for such discoveries. Even if the results are confirmed, it would not necessarily mean that the planet is home to life. Last year, scientists found traces of DMS on a comet, which suggested it can be produced in non-organic ways. However the concentration of the chemical observed on K2-18b appears to be thousands of times stronger than levels on Earth, strongly suggesting a biological origin, Madhusudhan said. Are we alone? K2-18b has long been considered the premier candidate for a "hycean planet" — an ocean world bigger than Earth with a hydrogen-rich atmosphere. These planets would not be expected to be home to intelligent alien life, but rather tiny microbes similar to those in Earth's oceans billions of years ago. Some research has questioned whether the currently proposed hycean planets are too close to their stars to support liquid water, including K2-18b, which orbits its star every 33 days. Raymond Pierrehumbert, a planetary physics professor at Oxford University, has conducted separate research indicating K2-18b is too hot for life. If the planet did have water, it would be "hellishly hot" and uninhabitable, he told Agence France-Presse, adding that oceans of lava were more plausible. Sara Seager, a professor of planetary science at MIT, called for patience, pointing to previous claims of water vapor in K2-18b's atmosphere that turned out to be a different gas. And within our solar system, Mars, Venus and moons such as Saturn's Enceladus all have "more chance to be realised as life-hosting," she told Agence France-Presse. Madhusudhan estimated that it would take just 16 to 24 more hours of Webb's time to confirm their findings, which could happen in the next few years. Even beyond K2-18b, Madhusudhan said Webb and future telescopes could allow humanity to discover life outside our home planet sooner than one might think. "This could be the tipping point, where suddenly the fundamental question of whether we're alone in the universe is one we're capable of answering," he said.

KOFA presents nature-focused film series for Earth Day
Program features documentary, art films that examine humanity's relationship with natural world The Korean Film Archive, a state-run institution dedicated to preserving and researching film heritage, will present "Perspectives on Nature," a lineup of documentary and experimental films focused on the natural world, from April 22 to May 8 at its Mapo-gu, Seoul headquarters. Timed for Earth Day, the program features works by contemporary filmmakers who explore landscapes and environments through distinctive artistic approaches. Italian director Michelangelo Frammartino contributes two films to the program. "Le quattro volte" (English: "The Four Times," 2010) unfolds in a Calabrian mountain town and moves through four phases -- human, animal, plant and mineral -- drawing on Pythagorean ideas. "Il buco" (English: "The Hole," 2021) documents the 1961 exploration of the nearly 700-meter-deep Bifurto Abyss in southern Italy. The film won the Special Jury Prize at the Venice Film Festival in 2021. Austrian filmmaker Nikolaus Geyrhalter's "Homo Sapiens" (2016) captures abandoned human spaces through static shots. Filmed at over 100 locations worldwide, the work lets the vacant structures speak for themselves, with no narration or people in sight. Sharon Lockhart's "Double Tide" documents a clam digger working in Maine's coastal mudflats using two 45-minute stationary shots. The program also features two works by Lucien Castaing-Taylor, director of Harvard University's Sensory Ethnography Lab. "Sweetgrass" (2009) follows Norwegian-American shepherds leading sheep through Montana's mountains. "Leviathan," (2012) co-directed with Verena Paravel, immerses viewers in the North American fishing industry, using GoPro cameras during the fishing crews' 20-hour shifts. Scott Barley's "Sleep Has Her House," (2017) shot entirely using an iPhone, blends long takes, still photography and hand-drawn images to portray a world emptied of human beings where supernatural forces emerge. Making its Korean premiere through the event is Digna Sinke's "Weemoed & Wildernis" (English: "Wistful Wilderness," 2010). The documentary tracks the island of Tiengemeten in the Netherlands as it shifts from farmland to wilderness over 13 years, woven together with the director's reflections. Castaing-Taylor will participate in Q&A sessions after his film screenings on May 2 and 3. All showings are free of charge. Full schedule details are available on the Korean Film Archive website.
