Toxicity of PM2.5 in Kolkata Spikes Sharply Beyond 70 µg/m³ Bose Institute Study Warns

Breaking News, Climate Actions, Environment

A recent study by Kolkata’s Bose Institute has revealed a concerning spike in the toxicity of PM2.5 particles once their concentration crosses 70 µg/m³ underscoring the urgent need for stricter pollution controls. The findings suggest that beyond this threshold, the health risks posed by PM2.5 particles increase sharply posing a greater threat to public health than previously understood. PM2.5, or fine particulate matter with a diameter of 2.5 micrometers or less, is among the most dangerous air pollutants. These particles can penetrate deep into the lungs and bloodstream, leading to serious respiratory, cardiovascular, and neurological issues. The study focused on the oxidative potential (OP) of PM2.5, which measures its ability to generate reactive oxygen species (ROS) compounds that ...

Life on the Climate Frontline Seoul Poorest Suffer the Most Pollute the Least

Breaking News, Climate Actions, Fact Check

In one of Seoul most impoverished corners residents of jjokbang-chon cramped windowless rooms often without basic amenities live quietly in the shadows of a rapidly developing city. These marginalized communities contribute the least to climate change, yet they endure its harshest effects. A new study from the University of Kansas exposes this stark climate injustice and calls for a shift in how the world addresses both poverty and the climate crisis. Dr. Joonmo Kang, assistant professor of social welfare at KU, spent a year living inside this so-called “last remaining slum” in the heart of South Korea’s capital. His goal was to understand how climate-related disasters shape the lives of the poorest residents. What he found was not just poverty but systemic neglect, environmental vulner...

kolkata Pollution Harming sundarbans Experts call for united climate action

Breaking News, Climate Actions, Disasters

Kolkata and the Sundarbans two regions separated by just 100 km, are now being seen as climate twins. At a recent meet in Kolkata, experts said that the air and water pollution from the city is damaging the Sundarbans mangroves an ecosystem that, in turn, acts as a vital buffer protecting Kolkata from extreme weather. The loss of these mangroves is making the city more vulnerable to climate shocks. At the heart of the meet was the Kolkata Declaration 2025, a five-point agenda focused on a shared climate security strategy. Experts stressed the need for an integrated approach rather than treating Kolkata and the Sundarbans as separate climate cases. The event, a citizen assembly, was organised by Tramjatra an international tram-lovers’ movement involving activists from Kolkata and Melb...

Experts Call for Unified Climate Strategy to Protect Kolkata and Sundarbans Push for Revival of Trams

Breaking News, Climate Actions

The climate futures of Kolkata and the Sundarbans are deeply intertwined, and experts now warn that failing to address them together could worsen the vulnerabilities of both regions. In a recent meeting held in Kolkata, scientists, activists, and urban planners came together to issue the ‘Kolkata Declaration 2025’, calling for an integrated climate security strategy, particularly highlighting the revival of eco-friendly public transport like trams as part of the solution. The air and water pollution from Kolkata is degrading the Sundarbans mangroves, which in turn weakens the city’s natural shield against cyclones and extreme weather. Experts said that despite being just 100 km apart, Kolkata and the Sundarbans are often dealt with separately in climate policies a mistake that needs urg...

Scientists Pioneer air-moisture Tech to Break down Plastic revolutionizing recycling

Breaking News, Climate Actions, Environment, Learning & Developments

In a breakthrough that could reshape plastic waste management, scientists have unveiled a pioneering method to break down polyethylene terephthalate (PET) using moisture from the air. This novel approach utilizing an inexpensive catalyst dismantles PET bonds and transforms the material into monomers the essential building blocks of plastics allowing for efficient recycling or upcycling into higher-value products. Published in Green Chemistry, a journal of the Royal Society of Chemistry, the study introduces a solvent-free, environmentally friendly solution to global plastic pollution. Unlike conventional recycling methods, which generate harmful byproducts and require significant energy input, this technique harnesses trace moisture from ambient air, making it safer and more sustainable...

Each Cigarette Costs Men 17 Minutes, Women 22 Minutes of Life: Study

Breaking News, Environment, Learning & Developments

London: Smoking takes a far greater toll on life expectancy than previously believed, a new study from University College London (UCL) reveals. For men, each cigarette smoked shortens life by 17 minutes, while for women, the cost is even higher at 22 minutes per cigarette. These figures surpass earlier estimates, which suggested an 11-minute loss per cigarette. Commissioned by the UK’s Department for Health and Social Care, the study urges smokers to make quitting their top resolution for the New Year. The research concludes that a pack of 20 cigarettes robs an average smoker of nearly seven hours of life. Over a lifetime, smokers who don’t quit lose approximately a decade of life, according to Dr. Sarah Jackson, a principal research fellow at UCL. “Smokers lose about the same num...
