Study Finds Greenland Ice 930 million cubic meters Fracturing at Alarming Rate

Study Finds Greenland Ice 930 million cubic meters Fracturing at Alarming Rate

Breaking News, Climate Actions, Disasters, Environment
Scientists have discovered that Greenland’s ice sheet has developed 930 million cubic meters of crevasses in just five years equivalent to a Great Pyramid of Giza-sized crack forming every few days. This rapid fracturing, particularly in fast-moving glaciers, could trigger a feedback loop that accelerates ice loss and raises global sea levels. A new study by researchers from the University of Florida, Durham University, and other institutions analyzed satellite imagery from 2016 to 2021, marking the first large-scale, multi-year assessment of Greenland’s crevasse formations. Automated machine learning techniques were used to track these changes, as manual methods proved too dangerous and time-consuming. Findings show uneven crevasse activity across the ice sheet, with some regions es...
Melting Glaciers Linked to Increased Earthquake Activity in Colorado’s Sangre de Cristo Mountains

Melting Glaciers Linked to Increased Earthquake Activity in Colorado’s Sangre de Cristo Mountains

Breaking News, Disasters, Environment
Southern Colorado’s Sangre de Cristo Mountains, known for their dramatic rise from the flat San Luis Valley, have long been shaped by tectonic activity and glacial forces. Now, a groundbreaking study in Geology suggests that the melting of alpine glaciers thousands of years ago may have significantly increased earthquake frequency in the region by relieving pressure on the underlying fault system. The research connects Earth’s changing climate to tectonic movements, a rare link that sheds light on how warming temperatures like those seen today might trigger fault activity. “Areas where glaciers are retreating or where hydrologic changes occur over active faults could experience elevated earthquake activity,” explained study co-author Sean Gallen, a geologist at Colorado State University...
Greenland Experiences One of the Largest Documented Glacial Lake Outburst Floods

Greenland Experiences One of the Largest Documented Glacial Lake Outburst Floods

Breaking News, Climate Actions, Disasters, Environment
A massive glacial lake outburst flood, among the largest ever recorded, has been documented in East Greenland, releasing over 3,000 billion litres of meltwater. The event, which occurred between September 23 and October 11, was caused by the sudden release of water from Catalina Lake into the Scoresby Sound fjord, as reported by researchers at the University of Copenhagen's Niels Bohr Institute. Notably, this marks the first time such a phenomenon has been observed in real-time. The flood was triggered when meltwater from Catalina Lake, held back by the Edward Bailey Glacier for over 20 years, carved a 25-kilometre-long tunnel beneath the glacier. This process caused the lake’s water level to plummet by 154 metres. Researchers equated the released volume of water to three times Denmark'...
Venezuela’s Last Glacier Melts Away  Grim Milestone in the Fight Against Climate Change

Venezuela’s Last Glacier Melts Away Grim Milestone in the Fight Against Climate Change

Breaking News, Climate Actions, Disasters
In a stark symbol of climate change's impact, Venezuela has become the first nation to lose all its glaciers, marking a somber milestone in the battle against global warming. Once boasting six glaciers spanning 1,000 square kilometers in 1910, the country now stands devoid of these icy formations, reduced to mere remnants unable to meet glacier classification criteria. The Humboldt glacier, or La Corona, nestled in the Sierra Nevada National Park, was the last to resist the thawing trend. Yet, its decline has been precipitous, with the once sprawling 4.5 square kilometer expanse reduced to less than 0.02 square kilometers, falling far short of the minimum size for glacier status. Professor Julio Cesar Centeno of the University of the Andes (ULA) lamented, "In Venezuela, glaciers no l...
