Venus Never Had Oceans Study Confirms Ending Decades of Speculation

Venus Never Had Oceans Study Confirms Ending Decades of Speculation

Breaking News, Learning & Developments, Space
Venus often referred to as Earth’s twin due to its similar size and rocky composition has been at the center of one of astronomy’s most enduring mysteries: Did it ever host oceans? A new study has finally provided an answer, and it’s not what some scientists had hoped. According to research published in the journal Nature Astronomy, Venus has likely been a dry, desolate world throughout its history. By analyzing the chemical composition of Venus’s atmosphere, scientists concluded that the planet’s interior has a remarkably low water content. This finding contradicts earlier hypotheses suggesting Venus might once have harbored oceans or even supported conditions favorable for life. The key lies in volcanic activity. On Earth, volcanic eruptions release large amounts of water vapor, wh...
Global Cities Fail to Meet Tree Canopy Goals Despite Abundance of Trees

Global Cities Fail to Meet Tree Canopy Goals Despite Abundance of Trees

Breaking News, Climate Actions, Environment
New research has revealed that most global cities, including Melbourne and Sydney, lack adequate tree canopy coverage, even though trees are abundant in urban landscapes. The study, published in Nature Communications, measured over 2.5 million buildings across eight cities using the '3-30-300' rule, a benchmark for sustainable urban nature access. Melbourne and Sydney Fall Short The study found that only 3% of buildings in Melbourne's inner suburbs had sufficient canopy cover, despite 44% of buildings having views of at least three trees. Central Sydney performed slightly better, with 17% of buildings shaded adequately, though 84% of buildings had views of three or more trees. Lead researcher Dr. Thami Croeser from the Centre for Urban Research said urgent action is needed to incr...
Study Finds Global Cities Falling Short on Tree Canopy Cover for Urban Health

Study Finds Global Cities Falling Short on Tree Canopy Cover for Urban Health

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...
Nepal’s Wildfires Intensify: Over 5,000 Blazes Recorded in 2024 Amidst Climate Change and Forest Mismanagement Concerns

Nepal’s Wildfires Intensify: Over 5,000 Blazes Recorded in 2024 Amidst Climate Change and Forest Mismanagement Concerns

Breaking News, Climate Actions, Disasters
Nepal is grappling with an alarming increase in the frequency and intensity of wildfires, with nearly 5,000 incidents recorded this year alone. This makes 2024 the second-worst year for wildfires since records began in 2002, surpassed only by the devastating fire season of 2021, which saw over 6,300 outbreaks. In the past 12 months, more than 100 people have lost their lives due to wildfires, and the capital city, Kathmandu, was shrouded in hazardous wildfire smog for days on end. Climate models predict that Nepal will continue to experience more frequent drought conditions in the future, likely exacerbating the wildfire situation. However, forest scientists suggest that the increasing incidence of wildfires is not solely due to climate change. They point to changes in Nepalese communit...
