Breaking News, Climate Actions, Environment
New research analyzing access to urban greenery across eight major global cities, including Melbourne and Sydney, reveals alarming gaps in tree canopy cover, despite the presence of visible trees. The study, published in Nature Communications, applies the ‘3-30-300’ rule, a sustainable cities benchmark, to evaluate urban nature access and its benefits. The '3-30-300' Rule Explained The rule, developed by Dutch urban forestry expert Professor Cecil Konijnendijk, suggests every home, school, and workplace should: Have a view of at least three trees. Be in a neighborhood with 30% tree canopy cover. Be within 300 meters of a park. While most buildings in the study met the "three trees" requirement, almost all cities fell short of the 30% canopy cover benchmark. Key Findi...

The Hidden Danger of Asbestos in Everyday Products

The Hidden Danger of Asbestos in Everyday Products

Breaking News, Environment, Fact Check, Learning & Developments
Asbestos widely used for its heat resistance and durability, has a dark legacy as a carcinogen responsible for mesothelioma, an aggressive and incurable cancer. Its use spanned diverse applications, from construction materials to the fake snow in classic films like The Wizard of Oz and White Christmas. Despite its hazards, asbestos wasn't banned in the UK until 1999, decades after its dangers were established. Today, concerns about asbestos persist not in construction but in cosmetics. Investigations have revealed traces of asbestos in some talc-based products, raising fresh alarms about its hidden risks in everyday items. How Asbestos Causes Mesothelioma Asbestos is a group of six fibrous minerals, including chrysotile (white asbestos) and crocidolite (blue asbestos), that can fr...
Can Cloud Seeding Help Delhi Breathe Cleaner Air?

Can Cloud Seeding Help Delhi Breathe Cleaner Air?

Breaking News, Climate Actions, Environment, Learning & Developments
Delhi is grappling with its annual air pollution crisis, with Air Quality Index (AQI) levels in the “severe plus” category, consistently above 450. In response, Delhi’s Environment Minister Gopal Rai has appealed to Prime Minister Narendra Modi for assistance in deploying cloud seeding a controversial technique to induce artificial rain and potentially reduce pollution levels. What is Cloud Seeding? Cloud seeding, also known as artificial rain, involves dispersing substances like silver iodide, potassium iodide, or dry ice into clouds to stimulate precipitation. These particles act as nuclei around which water droplets form, potentially triggering rainfall. The process can be carried out via aircraft, rockets, or ground-based generators. In theory, the rainfall generated could "wa...
Century of Climate Change From Discovery to Critical Decisions

Century of Climate Change From Discovery to Critical Decisions

Breaking News, Climate Actions, Environment
In September 1933, American meteorologist Joseph Kincer posed a now-crucial question: Is the climate changing? This query marked the beginning of modern efforts to understand humanity’s impact on the planet’s climate. By examining global temperature trends, Kincer concluded the world was warming, though he did not propose a cause. Five years later, in 1938, British engineer Guy Callendar attributed a 0.3°C rise in land temperatures over 50 years to increased carbon dioxide emissions from burning coal. This built upon earlier theories of the greenhouse effect, laying the groundwork for understanding human-driven climate change. Accelerating Warming Today, global climate monitoring relies on a sophisticated network of weather stations, satellites, and forecast models that track chan...
