  Nepal has sought $20 million in climate compensation from the United Nations loss and damage fund following devastating floods that killed more than 1,300 people and left over 5,500 missing, with the country warning that the disaster highlights the growing climate risks facing the Himalayas. Nepal Foreign Minister Shisir Khanal told The Guardian that the world’s largest and historically highest emitting economies must recognise their shared responsibility for helping vulnerable countries recover from climate related disasters. Nepal contributes less than 0.1 per cent of global greenhouse gas emissions. The floods struck in late August after the partial collapse of a melting glacier triggered a landslide and powerful flash floods across parts of Tibet and Nepal. Khanal descr...

Lake rich Arctic networks retain carbon longer, giving microbes more time to convert dissolved organic carbon into atmospheric CO₂, particularly during warm, low flow summers. Lakes and streams could play a more significant role in the global carbon cycle than previously understood, with a new Swedish study finding that lake rich Arctic stream networks release a greater share of carbon into the atmosphere instead of transporting it downstream. The study published in Geophysical Research Letters on August 25, 2026, found that lakes significantly extend the time water and carbon remain within interconnected stream networks. This longer residence time provides microbes with more opportunity to break down dissolved organic carbon (DOC) into carbon dioxide (CO₂), which can subsequently es...

  A dispute over Tata Group’s century-old soda-ash mining concession near Kenya’s Lake Magadi has divided local communities, with the government pushing for greater local processing and residents split over whether the Indian conglomerate should continue its operations. Kenyan President William Ruto has withdrawn Tata Group’s concession to mine trona, the mineral used to produce soda ash, arguing that the company has failed to establish local processing facilities that could create jobs and generate greater economic value for Kenya. The decision has sparked debate in Kajiado County, where Maasai communities depend on the area’s land and resources. While some residents say Tata’s departure could threaten essential services provided by the company, others support the government...

  Scientists in China have experimented with cloud seeding to produce artificial snowfall over the Muz Taw Glacier, with an early trial suggesting that the additional snow may have reduced ice loss by 14% to 17%. The experiment was conducted in August 2018 on the 3.2 kilometre long Muz Taw Glacier in the Sawir Mountains of Xinjiang, near the China Kazakhstan border. The glacier has been retreating continuously since 1959, with its decline accelerating in recent years. Researchers used 14 remotely controlled, solar powered generators to release silver iodide into suitable clouds. Silver iodide can act as an ice forming nucleus, helping water vapour in clouds develop into ice particles that can eventually fall as snow. A weather radar at the Jimunai Meteorological Station wa...

Marine protected areas cover around 10% of the world’s oceans on paper, but new research suggests less than 2% may actually be seeing meaningful recovery of marine ecosystems. The study, based on underwater biodiversity data collected from thousands of shallow coral and rocky reefs around the world, examined fish populations inside and outside marine protected areas. Researchers used fish biomass the total weight of fish on a reef as an indicator of whether ecosystems were genuinely recovering. Their findings challenge the assumption that an ocean area labelled “protected” is necessarily delivering effective conservation. The researchers estimate that less than 2% of the global ocean lies within protected areas where marine ecosystems are actually recovering. Even this figure is cons...

China has begun operations at what is described as the world’s largest iron ore magnetisation roasting project, using a new industrial process to convert low grade iron ore and discarded mine tailings into high grade iron concentrate. The facility in Anshan, Liaoning province, has passed official acceptance tests and is operating at full capacity, according to the Chinese Academy of Sciences (CAS). Developed by researchers at CAS’s Institute of Process Engineering, the plant can process about 5.56 million tonnes of refractory iron ore and mine tailings annually. The technology can upgrade material containing as little as 11 per cent iron into concentrate with an iron grade of about 65 per cent. Researchers say it is the first industrial scale technology capable of processing iron tai...

  Arizona engineers used ultra lightweight foam glass made from recycled containers at 19 locations along a 23 mile stretch of Interstate 17, allowing the highway to be widened without placing excessive weight on ageing drainage structures. When engineers began widening Interstate 17 north of Phoenix, Arizona they faced a problem beneath the road. Several concrete box culverts carrying stormwater had been built decades ago when the highway was narrower and were not designed to withstand the additional load that conventional soil and rock fill would have created. Rather than demolishing and rebuilding the structures, engineers adopted a lightweight alternative made from recycled glass. The material known as ultra lightweight foam glass aggregate was installed at 19 location...

  Swiss scientists have found that sheep’s wool could offer an environmentally friendly alternative to plastic sheets used to slow glacier melting, after a 200 square metre trial on the Tsanfleuron Glacier showed promising early results. The “Keep It Wool” experiment was carried out near the Glacier 3000 resort in western Switzerland, where researchers placed two 100 square metre wool blankets alongside conventional synthetic covers. Measurements taken throughout the summer indicated that the wool slowed ice loss by roughly the same amount as the synthetic geotextiles. Conventional glacier covers can reduce local melting by around 50 to 70 per cent by reflecting sunlight and limiting heat transfer. The wool blankets, made by Swiss textile company Fisolan, also withstood stron...

  Africa’s ambitious Great Green Wall project is shifting away from simply planting millions of trees and embracing a method developed by farmers in Niger that has helped regenerate an estimated 200 million trees naturally. The Great Green Wall launched by the African Union in 2007 was initially envisioned as an 8,000 kilometre belt of trees stretching from Senegal to Djibouti to combat desertification and land degradation across the Sahel. However, many planted seedlings struggled to survive the region’s harsh conditions. The breakthrough came from Australian agronomist Tony Rinaudo, who in the 1980s discovered that seemingly barren farmland in Niger still contained living tree stumps and extensive root systems beneath the soil. Rather than planting new trees farmers could p...

  Madanapalle, September 9: Artificial intelligence (AI), when combined with real time sensor data, satellite imagery and weather forecasts, could significantly improve flood prediction, water management and climate monitoring, experts said at a science workshop in Andhra Pradesh. The observations were made during a two day Science Academies Workshop on “AI and Space Technologies for Climate and Resource Monitoring” held at Madanapalle Institute of Technology and Science (MITS) Deemed to be University in Annamayya district. Indian Institute of Science (IISc), Bengaluru professor D. Nagesh Kumar said integrating data from sensors, satellites and weather forecasting systems with AI could support smarter water resource management. Such systems could help authorities anticipat...
