Scientists have discovered an alarming rate of methane seeps escaping from cracks in the Antarctic seabed due to warming, raising concerns that global warming predictions may be underestimated. Over 40 seeps were found in the Ross Sea, many in previously studied sites, suggesting they are new. Methane, a super-polluting gas, traps around 80 times more heat than carbon dioxide in its first 20 years in the atmosphere. The fear is that these seeps could rapidly transfer methane into the atmosphere, contributing to further climate change.
