Global Study Warns of Flawed Climate Metrics as New Framework Challenges Carbon Accounting System

Global Study Warns of Flawed Climate Metrics as New Framework Challenges Carbon Accounting System

Climate Actions, Environment, Fact Check
    A new scientific study is raising serious questions about how the world measures global warming, warning that current methods may be underestimating the true impact of certain greenhouse gases and misguiding climate policy and carbon markets. Published in the journal Environmental Research Letters the research introduces an alternative framework called Radiative Forcing-based Accounting (RFA), which aims to more accurately capture how different greenhouse gases affect Earth’s temperature over time. The study argues that the widely used system for measuring emissions based on carbon dioxide equivalents fails to reflect the real-time warming effects of gases like methane. For decades, climate policy has relied on a standard unit known as carbon dioxide equivalent (C...
Rising Heat Linked to Surge in Teen Depression, New Study Warns

Rising Heat Linked to Surge in Teen Depression, New Study Warns

Climate Actions
    As global temperatures continue to break records year after year, scientists are raising fresh concerns about a less visible but deeply troubling consequence of extreme heat—its impact on adolescent mental health. New research from the University of Denver suggests that rising temperatures may be contributing to increased risks of depression among teenagers. The past decade has seen a consistent upward trend in global temperatures, with recent winters in parts of the United States reaching historic highs. Several states, including Colorado, recorded their warmest winters on record, while others experienced near-record conditions. Experts warn that such extreme heat events are not only affecting physical health but may also be influencing emotional and psychological w...
Scientists Warn Parts of Antarctica’s Ice Sheets Are Retreating Faster Than Expected

Scientists Warn Parts of Antarctica’s Ice Sheets Are Retreating Faster Than Expected

Climate Actions, Environment
    A new scientific study has revealed that some parts of Antarctica are losing grounded ice much faster than researchers had previously anticipated. While large sections of the continent’s coastline remain stable, several vulnerable regions are showing rapid retreat that could influence global sea-level rise in the future. The study analyzed satellite data collected between 1992 and 2025 to track changes in the “grounding line,” the critical boundary where glaciers stop resting on land and begin floating over the ocean. Scientists say this boundary is crucial because once glaciers lose their grip on bedrock, they can slide into the ocean much faster. Researchers found that about 77 percent of Antarctica’s coastline remained largely stable over the past three decades...
Under Ice Robot Detects Warm Water Intrusions Beneath Antarctica’s Thwaites Glacier

Under Ice Robot Detects Warm Water Intrusions Beneath Antarctica’s Thwaites Glacier

Climate Actions, Fact Check
    A torpedo-shaped underwater robot that spent eight months drifting beneath Antarctica’s vast Thwaites Glacier has detected concentrated flows of warm ocean water eroding the glacier from below a development scientists have long warned could accelerate global sea-level rise. The autonomous submersible, known as Icefin, was deployed through a narrow borehole drilled deep into the ice in West Antarctica. Operating without GPS beneath hundreds of metres of ice, it mapped water temperatures, salinity and melt rates in areas previously unreachable by humans or satellites. After 240 days under the glacier, data transmitted back to researchers revealed pulses of unusually warm, salty water pushing inland beneath the ice shelf. Rather than melting uniformly, the water appe...

NGT clears Great Nicobar Mega Project despite Ecological and Seismic Warnings

Climate Actions, Idea & Innovations
    In February 2026, India National Green Tribunal (NGT) delivered two sharply contrasting rulings one condemning environmental violations as grave harms to human life, and another upholding environmental clearance for a massive infrastructure project on Great Nicobar Island. The decision to greenlight the Rs. 81,000–92,000 crore Great Nicobar mega-project has triggered intense criticism from scientists, environmentalists, and tribal rights advocates. What the project entails The proposed development spans about 166 sq km and includes: • An international container transhipment port • A greenfield airport • A power plant • A new township envisioned as an “Indian Singapore or Hong Kong” To execute this vision, approximately 130 sq km of forest land wo...
Ghana Draws a Red Line: Forests Declared More Valuable Than Gold After Mining Law Repeal

Ghana Draws a Red Line: Forests Declared More Valuable Than Gold After Mining Law Repeal

Climate Actions, Environment
Ghana’s government reversed what many environmentalists had called one of the most damaging pieces of legislation in the country’s history. The repeal of regulations that allowed mining inside forest reserves marked a rare victory for conservation, driven not by courts or corporations, but by sustained public pressure. The now-scrapped law, passed in 2022, had opened nearly 90 percent of Ghana’s forest reserves to mining activity, including areas of global ecological importance. These forests, spanning more than nine million hectares, play a critical role in water security, climate regulation and the livelihoods of forest-dependent communities. Law That Triggered an Unprecedented Backlash Ghana is Africa’s largest gold producer and among the world’s top contributors to mining-rela...
India Tiger Success Faces a New Challenge as States Reconsider Forest Carrying Capacity

India Tiger Success Faces a New Challenge as States Reconsider Forest Carrying Capacity

Climate Actions, Environment
    India’s globally celebrated tiger conservation programme is entering a complex phase as rising tiger numbers begin to strain forest ecosystems and intensify human-wildlife conflict. Wildlife scientists and forest officials across tiger-rich states are now calling for a serious rethink of the concept of “carrying capacity”, a term that has long sparked discomfort among conservationists but is gaining renewed urgency. Several states with strong tiger populations, including Karnataka, have flagged the issue, arguing that while conservation measures have boosted numbers, forest landscapes themselves have not expanded. This growing imbalance is expected to be a key discussion point at the upcoming Global Big Cat Alliance summit to be held in Bandipur and Nagarhole Tiger R...

Lower GST on Recyclables Can Accelerate Green Economy, CSE Tells Finance Ministry Ahead of Budget 2026

Climate Actions, Fact Check
    The Centre for Science and Environment (CSE) has urged the Union government to rationalise the goods and services tax on recycled materials, arguing that lower GST rates could significantly strengthen India’s green economy, support small businesses and bring millions of informal waste workers into the formal system. The recommendations were submitted to Finance Minister Nirmala Sitharaman ahead of the Union Budget 2026. According to the Delhi-based think tank, tax reform in the waste sector is critical if India is to maintain momentum on green growth and move closer to its Net Zero by 2070 goal. While recent budgets have prioritised clean energy and industrial decarbonisation, CSE says the recycling economy remains constrained by a tax structure that treats recycled ...
