Urbanisation Disappear Eight Dragonfly Species from Pune as 27 New Ones Discovered

Breaking News, Climate Actions, Environment

A recent study has revealed a dramatic shift in Pune’s dragonfly population, with eight species vanishing while 27 new species have been discovered. Conducted by researchers and citizen scientists, the study attributes the loss of local species to land-use changes, water pollution, shifting weather patterns, and rapid urbanisation. Published in the International Journal of Tropical Insect Science the research was led by scientists from Maharashtra Institute of Technology-World Peace University and conducted between 2019 and 2022 across 52 locations in Pune. The city, which falls within the Western Ghats and Deccan Peninsula biogeographic zones, is home to a rich diversity of odonates, the insect order that includes dragonflies and damselflies. Dragonflies as Environmental Indicators ...

Women in Least Developed Nations Struggle for Voice in Climate Talks

Breaking News, Climate Actions, Fact Check, Thoughts & Talks

A recent study has revealed that women from the world’s least developed countries (LDCs) face significant barriers to participating in global climate negotiations. Conducted by the International Institute for Environment and Development (IIED), the research highlights the gender imbalance in United Nations Framework Convention on Climate Change (UNFCCC) discussions, particularly among delegates from the 45 LDCs. Since 2008, women have made up only one in three UNFCCC delegates, with just 10% serving as heads of delegation. The study, which included surveys and case studies from Rwanda, Mozambique, and Sierra Leone, found that cultural norms, restrictive laws, and institutional barriers limit women’s roles in climate talks. Limited access to education, training, financial resources, and ...

Tree Rings Reveal Climate Change’s Role in Intensifying Drought Across Eurasia

Breaking News, Climate Actions, Environment

Scientists have long struggled to distinguish natural hydroclimatic variability from human-induced climate change when analyzing shifting drought conditions worldwide. While complex computer models can simulate past climate fluctuations, they often carry biases that affect regional drought estimates. Now, a groundbreaking study using tree rings provides compelling evidence that global warming is driving 21st-century drought patterns across Europe and Asia. A team of researchers, led by Kate Marvel and colleagues, turned to the Great Eurasian Drought Atlas (GEDA) a vast collection of tree ring records spanning 1,000 years to reconstruct historical drought trends. Because tree rings grow wider in warm, wet years and thinner in dry, cold years, they serve as a natural climate archive, offe...

Vanishing Giants India Farmlands Lose Millions of Large Trees, Raising Environmental Concerns

Breaking News, Climate Actions, Environment

India has witnessed a dramatic decline in large trees across its farmlands over the past decade, with nearly 5.6 million trees disappearing between 2018 and 2022 alone, a new study has revealed. Researchers using satellite imagery from 2010 to 2022 found that in some regions, up to 50% of large trees have been lost, raising serious concerns about the impact on biodiversity, soil health, and climate resilience. The study identified central Indian states like Maharashtra and Telangana as hotspots for tree loss, with nearly 2.5 million trees vanishing between 2011 and 2018. Rajasthan and Chhattisgarh recorded the highest densities of tree loss, with about 22 trees disappearing per hectare. India’s land-cover data shows that 56% of the country is under farmland, while forests cover only ...

How Satellites AI Supercomputers Are Changing the Battle Against Wildfires

Breaking News, Climate Actions, Learning & Developments, Space, Tech

As wildfires raged through Los Angeles in January 2025, cutting-edge technology played a crucial role in firefighting efforts. Satellites, artificial intelligence, and advanced computer models helped firefighters track, predict, and combat the fast-moving blazes. Fire detection has come a long way from the early 20th-century lookout towers built after the devastating Great Fire of 1910. Today, California alone has over 1,100 cameras scanning for smoke, with AI continuously analyzing images to detect fires before they spread. NOAA satellites provide real-time heat signatures, fire perimeter mapping, and air quality assessments. Once a fire is detected, predicting its behavior becomes essential. Advanced computer simulations use fuel models, terrain data, and real-time weather forecast...

Fujitsu, Yokohama Univ Predict Typhoon Tornadoes Using Supercomputer

Breaking News, Climate Actions, Disasters, Learning & Developments

Fujitsu Limited and Yokohama National University have achieved a groundbreaking milestone by developing the world's first real-time prediction system for multiple tornadoes associated with typhoons. Utilizing Fujitsu’s Fugaku supercomputer and an enhanced version of the Cloud Resolving Storm Simulator (CReSS), this innovation significantly improves disaster preparedness by delivering more accurate and faster tornado forecasts. This advanced system reduces prediction times from over 11 hours to just 80 minutes, allowing forecasts up to four hours ahead of tornado occurrences. Notably, the prediction model only used 5% of Fugaku’s computational capacity, demonstrating the potential for larger-scale simulations and even quicker predictions. Addressing Tornado Prediction Challenges Ab...

New Study Reveals Why Rock-Ice Avalanches Travel Farther, Proposes Key Friction Equation

Breaking News, Learning & Developments

Rock avalanches are a significant hazard in mountainous regions, but when ice is present, the risk escalates dramatically. In colder regions, rock-ice avalanches avalanches consisting of both rock and ice tend to travel much farther than those made up of rock alone. Despite this well-known behavior, scientists have long struggled to understand the exact mechanism behind this increased mobility. A recent study led by Fan et al. [2024] sheds new light on this mystery using advanced experimental methods. The researchers developed a state-of-the-art flume setup equipped with high-speed cameras that can operate at temperatures as low as −10°C. This allowed them to closely observe how ice fragments interact with rock fragments during avalanche simulations, offering unprecedented insight into ...

Study Finds Dust Storms Cost US $154B Annually Impacting Healthcare

Breaking News, Climate Actions, Fact Check

A new study in Nature Sustainability reveals that wind erosion and blowing dust cost the U.S. economy around $154 billion each year, impacting healthcare, transportation, agriculture, energy, and households. Conducted by researchers from The University of Texas at El Paso (UTEP), George Mason University, and the U.S. Department of Agriculture, the study highlights the growing societal burden of dust storms, which are worsened by human land use, drought, and declining water resources. Thomas Gill, Ph.D., a UTEP earth sciences professor, emphasized the significance of these findings. "Blowing dust is a major expense and creates great societal harm," he said, comparing its costs to those of hurricanes and other natural disasters. Healthcare costs make up a significant portion of the tot...

Climate Change Threatens Mediterranean Fisheries With 41% Drop in River Flow

Breaking News, Climate Actions, Environment

A new study by European scientists warns that freshwater flowing through rivers into the Mediterranean Sea could decline by as much as 41% due to climate change. The research, published on February 3, 2025, outlines a worst-case scenario in which global temperatures rise by 4°C above pre-industrial levels, drastically altering coastal ecosystems and threatening the region’s fisheries. The decrease in river flow would reduce freshwater and nutrient inputs, leading to lower primary productivity in the Mediterranean’s marine ecosystem. This would have cascading effects on the food chain, ultimately impacting commercially valuable seafood species. "The results show that 41% less river flow could slash marine productivity by 10% and fish biomass by 6% in the Mediterranean, leading to annu...
