    High above the Arctic Ocean, one of Greenland’s last great floating glacier tongues is flexing, fracturing and draining in dramatic bursts offering scientists a rare, real-time window into how climate change can destabilise massive ice structures. On Greenland’s remote northeast coast lies the Nioghalvfjerdsbræ better known as the 79°N Glacier. It is one of only three remaining large floating glacier tongues in Greenland, making it critical for understanding future sea-level rise. A Lake That Vanishes Overnight In 1995, satellite imagery revealed a vast meltwater lake sitting atop the glacier tongue a 21-square-kilometre basin formed by rising air temperatures. Since then, researchers from the Alfred Wegener Institute (AWI) have tracked its unusual behaviour. ...

    In a significant move to protect the fragile island ecosystem of Lakshadweep, the National Green Tribunal (NGT) has directed that all tourism-related activities in the archipelago must operate strictly within its ecological carrying capacity and adhere to robust environmental safeguards. The order places responsibility on the Lakshadweep Tourism Development Corporation (LTDC) to ensure that tourism expansion does not compromise the islands’ delicate coral atoll ecosystem. Tent City Projects Under Scrutiny The tribunal specifically addressed the “tent city” tourism project involving prefabricated structures on Bangaram Island and the northern and southern parts of Thinnakara Island. It directed that these developments must remain strictly within the ecological l...

    The words used to describe plastic recycling may be shaping public opinion more than the science itself. A new study from the University of Manchester argues that commonly used terms such as “upcycling” and “downcycling” can distort how plastic waste solutions are perceived sometimes masking their true environmental and economic impact. The research, conducted by the university’s Sustainable Materials Innovation Hub, calls for clearer, more evidence-based communication around plastic end-of-life strategies. Published in Cambridge Prisms: Plastics, the paper questions whether directional labels accurately reflect sustainability outcomes or simply imply value judgments without sufficient analysis. When Language Influences Sustainability “Upcycling” typically carr...

    Extreme ocean waves once dismissed as maritime folklore are now being captured in precise detail from space and the latest satellite data are prompting new concerns among scientists and shipping operators. Recent observations show individual waves in the Pacific reaching heights of up to 35 metres taller than a 10-storey building even in the absence of so-called “super hurricanes.” Researchers say these measurements suggest that dangerous sea states may be developing under conditions previously considered routine. For decades, rogue waves were treated as exaggerated sea tales. That perception began to shift in the 1990s when radar altimeters aboard European and American satellites started systematically recording wave heights across the globe. Today, agencies i...

    Forests do far more than store carbon or shelter wildlife. They actively regulate temperature, humidity and rainfall and when they disappear, the climate shifts almost immediately. A recent study published in Communications Earth & Environment provides striking quantitative evidence of this effect. According to the research, when forest cover drops below 60 percent, local weather patterns begin to change significantly: surface temperatures rise, evapotranspiration declines, and rainfall becomes less frequent. The Hidden Cooling System of Forests Forests function as natural climate stabilisers. Through evapotranspiration the combined process of water evaporating from soil and transpiring from plant leaves vegetation releases moisture into the atmosphere. Thi...

    More than six decades after their lands were acquired for one of independent India’s earliest thermal power projects, many Adivasi families in Jharkhand’s Bokaro district continue to live without secure housing, stable livelihoods or even legal electricity. Their story is intertwined with the rise of the Damodar Valley Corporation (DVC), established in 1948 as one of India’s first major river valley development projects. Modeled partly on the Tennessee Valley Authority in the United States, the DVC was envisioned as a symbol of modern nation-building controlling floods, generating electricity and accelerating industrial growth. In the late 1950s, land was acquired to build the Chandrapura Thermal Power Station. Spread across 1,800 acres in what is now Jharkhand’s ...

    On the shifting edge of the Tengger Desert, thin rows of poplars stand like a fragile barricade against advancing sand. For decades, China has pursued one of the most ambitious environmental engineering projects in history a vast afforestation drive widely known as the Green Great Wall, designed to halt the spread of the Gobi Desert and other northern deserts. From satellite imagery, the results appear striking. Expanding green belts cut across once-barren land. Officials report that tens of millions of hectares of forest and shrubland have been added since the late 1970s. In cities once battered by frequent dust storms, residents say the “black wind days” have become less common. But beyond the headlines and aerial photographs, scientists are raising a more compl...

    The rapid melting of Arctic sea ice may be reshaping one of the world’s most critical weather systems India’s summer monsoon according to new research by scientists at the Indian Institute of Tropical Meteorology (IITM). The study finds that declining Arctic sea ice, particularly in early summer, is closely linked to stronger and increasingly westward-shifting monsoon rainfall across India in the later months of the season. India’s summer monsoon delivers nearly 80% of the country’s annual rainfall between June and September, sustaining agriculture, replenishing reservoirs, and supporting hundreds of millions of people. In recent decades, meteorologists have observed two significant trends: an overall rise in rainfall intensity and a noticeable drift of heavy late...

    From China to Europe and North America, rivers are being transformed by intensifying droughts, floods and heatwaves with mounting consequences for biodiversity and water security, according to a new global review published in The Conversation. Researchers from institutions including the University of Canterbury, the University of Washington, and Inrae say extreme climatic events are pushing river ecosystems beyond their limits, often causing irreversible damage. Rivers Under Pressure In 2022, unprecedented heat and drought reduced sections of the Yangtze River the world third-longest river to critically low levels. While the economic impacts on hydropower, shipping and industry were widely reported, scientists say the ecological fallout was less visible but equ...

    India’s tigers are exhibiting noticeable behavioural changes, including a rise in attacks on humans and increased movement outside protected areas, according to the State of India’s Environment 2026 report released by the Centre for Science and Environment (CSE). The report, unveiled during the Anil Agarwal Dialogue 2026 near Alwar, suggests that ecological degradation, habitat saturation and human proximity to forests are reshaping the behaviour of the country’s big cats. Between January and June 2025, at least 43 people were killed in tiger-related incidents near reserves across India. During the same period in 2024, 44 fatalities were recorded. In four of the 43 attacks in 2025, tigers reportedly consumed parts of the victims. While tigers rarely become habi...
