Antarctic Ice Sheet Near Irreversible Melting Tipping Point, Study Warns

Breaking News, Climate Actions, Environment

A groundbreaking new study has revealed that the Antarctic Ice Sheet Earth’s largest contributor to potential sea-level rise may be dangerously close to an irreversible tipping point, beyond which melting will continue even if global temperatures are stabilised or reduced. Scientists from Norway’s NORCE Research, the UK’s Northumbria University, and Germany’s Potsdam Institute for Climate Impact Research (PIK) have confirmed that the ice sheet is showing signs of “hysteresis” a phenomenon where a system continues on its path regardless of changes to the initial conditions. In this case, it means that the melting of Antarctica’s vast ice reserves could continue even without additional global warming. Using sophisticated computer simulations known as Parallel Ice Sheet Model (PISM), th...

Antarctic Ice Melt Slows World Strongest Ocean Current Raising Climate Alarm

Breaking News, Climate Actions, Fact Check

The Antarctic Circumpolar Current (ACC) world's strongest ocean current now slowing down due to unchecked melting of the Antarctic ice sheet. This powerful current flows from west to east around Antarctica plays a crucial role in regulating global climate and ocean circulation. A team of researchers from the University of Melbourne analyzed high resolution ocean and sea ice simulations to assess how changing temperature, salinity and wind conditions are affecting ocean currents. Their findings published in Environmental Research Letters suggest that the influx of freshwater from melting ice is significantly weakening the ACC. Associate Professor Bishakhdatta Gayen said "The ocean is extremely complex and finely balanced, If this current ‘engine’ breaks down there could be severe cons...

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...

Arctic Heatwave North Pole Temperatures Soar 20°C Above Normal, Pushing Ice to Melting Point

Breaking News, Climate Actions, Environment

In a dramatic climate event, temperatures at the North Pole surged more than 20°C above average on Sunday, surpassing the melting threshold for ice. According to European and U.S. weather models, regions north of Svalbard, Norway, had already experienced an 18°C temperature anomaly on Saturday, bringing actual readings dangerously close to 0°C. By Sunday, the anomaly had exceeded 20°C, marking one of the most extreme winter warming events recorded in the Arctic. “This was a very extreme winter warming event,” said Mika Rantanen, a scientist at the Finnish Meteorological Institute. “Probably not the most extreme ever observed, but still at the upper edge of what can happen in the Arctic.” Scientists attribute this rapid warming to a combination of human-induced climate change and r...

Greenland Ice Sheet Cracking at Alarming Rate, Study Warns

Breaking News, Climate Actions, Disasters

Over the past five years, an astonishing 930 million cubic meters of crevasses have opened across Greenland’s ice sheet equivalent to a crack the size of the Great Pyramid of Giza forming every few days. This rapid increase in fracturing, particularly in the ice sheet’s fast-moving regions, could trigger a dangerous feedback loop that accelerates ice loss and raises global sea levels. A new multi-year study, led by researchers from the University of Florida and Durham University, provides the first large-scale analysis of Greenland’s glacier crevasses, spanning 2016 to 2021. The findings reveal significant variations across the ice sheet, with some areas especially in the west initially experiencing fewer crevasses, only to see an uptick in recent years. Overall, the study detected a sh...

Melting Ice Reveals 5,900-Year-Old Forest in Rocky Mountains

Breaking News, Environment, Learning & Developments

The melting ice of the Rocky Mountains has unearthed a stunning archaeological discovery: a 5,900-year-old whitebark pine forest preserved in remarkable detail. Located on the Beartooth Plateau in Wyoming at an elevation of 3,100 meters well above today’s tree line the discovery offers an unprecedented glimpse into ancient climates while raising pressing questions about the future. The frozen forest, uncovered during an archaeological survey, includes more than 30 well-preserved trees. Whitebark pine, a species that no longer grows at such heights, flourished there during a significantly warmer period in Earth's history. “This discovery offers us a window into past conditions at high elevations,” said Cathy Whitlock of Montana State University. Tree ring analysis and carbon dating re...

World Largest One Trillion Iceberg Melt Down After Decades of Stillness

Breaking News, Climate Actions, Disasters, Environment

The world’s largest and oldest iceberg, A23a, has broken free after decades of being grounded on the seabed near Antarctica. This colossal "mega-berg," weighing over a trillion tonnes and spanning an area twice the size of Greater London, is now drifting into the Southern Ocean. A23a was calved from Antarctica’s Filchner Ice Shelf in 1986, marking the beginning of its extraordinary journey. For over 30 years, it remained grounded on the seabed of the Weddell Sea. In 2020, it began to shift northward, but its progress was slowed by a Taylor Column, an oceanographic phenomenon that kept it spinning in one spot for months. Dr. Andrew Meijers, an oceanographer at the British Antarctic Survey, remarked, “It’s exciting to see A23a on the move again after periods of being stuck. We are curi...

Greenland Accelerating Ice Melt Could Raise Sea Levels by One Meter by 2100

Breaking News, Climate Actions, Environment

The melting of Greenland’s ice sheet is accelerating at an alarming pace, with the potential to lose between 964 and 1,735 gigatons of ice annually by 2100 under high greenhouse gas emissions (SSP585), according to new research led by the University of Liège. This massive ice loss could lead to a rise in global sea levels by up to one meter, putting millions in coastal regions at risk. The Scale of the Crisis Recent studies, including one published in Geophysical Research Letters, reveal that Greenland currently contributes 25% to global sea-level rise, adding 0.6 millimeters per year. If melting continues unabated, this contribution could surge dramatically by the end of the century. Three regional climate models RACMO, MAR, and HIRHAM offer slightly varying predictions due to di...

Arctic Glaciers Raises the Environmental Concerns due to traces of Common Sunscreen Ingredients Found

Climate Actions, Environment

In a paper published by the researchers, they noted that, for some of these chemicals, it marks the first time their presence has been reported in the snow in Svalbard. The chemicals include UV filters used in sunscreens, such as benzophenone-3 (BP3), and fragrances found in soaps and shampoos. The findings highlight the increasing challenge of understanding the distribution and behavior of these contaminants in remote regions, where primary sources of pollution remain largely unknown. The far-reaching consequences of human activity on the environment are once again underscored as a study reveals traces of 13 common ingredients found in sunscreens and personal care products in the snowpack of five Arctic glaciers in the Svalbard archipelago. The study, conducted by polar scientist Maria...
