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 ...

India Temperature Trends Remain a Mystery, Says Harvard Atmospheric Scientist

Breaking News, Climate Actions

India temperature trends continue to baffle climate scientists with one of the leading voices in atmospheric science, Dr. Loretta J Mickley of Harvard University, admitting that experts still don’t fully understand the forces shaping the country’s warming patterns. In an interview wirh Mickley explored the complex role aerosols play in India’s climate and why projections for the future remain highly uncertain. Despite decades of rising global temperatures, India has warmed only about half as much as the rest of the Northern Hemisphere since 1950, based on NASA data using 1951–1980 as a baseline. While this may seem like a positive anomaly, it raises significant scientific questions. Mickley, senior research fellow and co-lead of the Atmospheric Chemistry Modeling Group at Harvard Say...

Global Warming Will Make The Average Person 40% Poorer, Study Warns

Breaking News, Climate Actions

A new study by Australian scientists has revealed that the impact of global warming on wealth has been significantly underestimated. According to the research if global temperatures rise by 4 degrees Celsius, the average person's wealth could decrease by as much as 40%, which is almost four times higher than previous estimates. The study also forecasts a 16% reduction in global GDP per person if temperatures increase by just 2 degrees Celsius, much higher than earlier predictions that suggested a 1.4% drop. Analysis corrects an oversight in current economic model underpinning global climate policy, toppling previous carbon benchmarks. Even if countries meet both near-term and long-term climate targets, the study suggests that global temperatures will still rise by 2.1 degrees Celsius...

Lakes Across the Globe Losing Oxygen at Unprecedented Rate as Heat Waves and Climate Change Drive Deoxygenation Crisis

Breaking News, Climate Actions

Lakes around the world are rapidly losing oxygen, a trend that scientists warn could have devastating consequences for aquatic life, global food security, and climate stability. A new study published in Science Advances on March 21, 2025, has revealed that deoxygenation in global lakes is occurring at a rate faster than that observed in oceans and rivers. The research led by Yibo Zhan of the Chinese Academy of Sciences, found that 83 percent of the 15,535 lakes studied are experiencing continuous oxygen loss, with the decline driven primarily by rising global temperatures and an increasing frequency of heat waves. The study identified long-term climate warming as the primary driver of oxygen loss, accounting for 55 percent of the depletion in surface waters. As temperatures rise, the...

Bengaluru Student Study Shows Rejuvenating Lakes Can Solve Water Crisis

Breaking News, Climate Actions, Fact Check

Once known as the ‘City of Lakes’, Bengaluru now faces severe water shortages with demand outstripping supply as rapid urbanisation takes its toll. However student-led research project under the Anveshana initiative suggests that restoring the city’s historical lake system could help achieve water self-reliance. Historically Bengaluru’s lakes functioned as interconnected reservoirs storing rainwater and supporting agriculture drinking water needs, and groundwater recharge. They also helped control floods by gradually releasing excess rainfall. However over the decades, urbanisation and groundwater extraction led to widespread lake neglect and encroachment, with many turning into sewage dumps. The city, now reliant on importing water from the Cauvery River, faces a growing demand-supp...
