Methane Leaks in Antarctica Raise Climate Concerns

A team of Spanish scientists has discovered significant methane emissions from the Antarctic seabed, raising alarms about potential consequences for global warming. Using the research vessel Sarmiento de Gamboa, the expedition identified methane columns extending up to 700 meters long and 70 meters wide on February 8, 2025. Geologist Ricardo León noted that these emissions could act as an "environmental bomb," as methane is approximately 30 times more potent at trapping heat than carbon dioxide, according to statements reported by EL PAÍS.

The expedition, which began on January 12, aimed to investigate hypothesized leaks caused by the melting of the Antarctic ice sheet and post-glacial rebound, a phenomenon that reduces pressure on the land. The recent findings align with other studies showing rising temperatures in the region—more than 3 degrees Celsius in the last 50 years.

In addition to methane emissions, researchers warned about the potential for significant landslides that could result in tsunamis, similar to the historic Storegga landslide in the Arctic. "When methane hydrates turn into gas, their volume can increase 160-fold, potentially triggering catastrophic geological events," León emphasized.
