Glaciers Losing Ice at Alarming Rate, Warns World Meteorological Organization

A team of Spanish scientists aboard the research vessel Sarmiento de Gamboa has uncovered substantial methane emissions from the Antarctic seabed, posing significant risks for global warming. The methane, which is up to 30 times more potent than carbon dioxide, is released from previously stable methane hydrates that have been accumulating for approximately 20,000 years. According to geologists Ricardo León and Roger Urgeles, the emissions consist of columns up to 700 meters long and 70 meters wide, comparable to an environmental bomb threatening Earth's climate, as reported in EL PAÍS.
This phenomenon is attributed to the post-glacial rebound, where diminishing ice weight allows the land mass to rise, releasing trapped methane. The researchers estimate that around 24 gigatons of carbon, equivalent to two years of global human emissions, are stored in this area. Additionally, the volatility of marine sediments risks large-scale landslides that could trigger tsunamis, reminiscent of historic events like the Storegga landslide in the Arctic. Their findings signal a concerning new chapter in the response of polar regions to climate change.
