Breaking News, Climate Actions, Environment
India is likely to receive above-normal rainfall during the 2025 southwest monsoon season raising hopes for strong agricultural output and economic growth. According to the Long Range Forecast (LRF) issued by the India Meteorological Department (IMD) on April 15, 2025 the country could see 105% of the long-period average (LPA) rainfall between June and September. This optimistic forecast comes amid global and regional climatic conditions that seem to favor a good monsoon. Reduced snow cover over Eurasia and the northern hemisphere, along with neutral conditions in the Pacific and Indian Oceans, are key factors supporting this outlook. The IMD’s forecast places the probability of above-normal rainfall (105–110% of LPA) at 33% while the chance of excess rainfall (more than 110% of LPA)...

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

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 ...

New Floodplain Study Offers Breakthrough in Building Climate-Resilient Communities

New Floodplain Study Offers Breakthrough in Building Climate-Resilient Communities

Breaking News, Climate Actions, Environment
As climate change fuels more intense and frequent storms, strengthening flood mitigation strategies has become a top priority. Lives, agriculture, and critical infrastructure are at increasing risk, particularly in downstream communities where effective flood resilience is essential. A new study from the University of Vermont (UVM) sheds light on a powerful yet underutilized natural ally in this fight: floodplains. Floodplains the low-lying land flanking rivers and streams act as nature’s shock absorbers. By temporarily storing excess water during floods, they reduce flood peaks, slow water velocity, and limit erosion in a process called attenuation. But not all floodplains work the same way. The latest research published in the Journal of Geophysical Research: Earth Surface introduces ...
