🗞️ Driving the news: Scientists have discovered over 40 previously undetected methane seeps in Antarctica’s Ross Sea — suggesting a rapid and possibly climate-driven increase in the release of this potent greenhouse gas from the seafloor
• These findings, published in Nature Communications, mark a dramatic shift from earlier assumptions that Antarctic methane seeps were rare
• Researchers fear this could signal a broader and underappreciated feedback loop accelerating global warming
🔭 The context: Methane, which traps 80 times more heat than carbon dioxide over a 20-year period, exists in vast quantities beneath the ocean floor
• Typically, methane is partially consumed by seabed microbes before it reaches the atmosphere, but little is known about how Antarctic seeps function
• Until now, only one active seep had been confirmed in the region
• The discovery of dozens of new ones at previously well-studied sites suggests these are newly formed and possibly linked to environmental changes
🌍 Why it matters for the planet: If large volumes of methane are escaping directly into the atmosphere, they could significantly amplify global warming
• Current climate models do not account for Antarctic seabed methane emissions, potentially underestimating future temperature rise
• The seeps may also impact marine ecosystems by altering local chemistry and microbial balances
• As Antarctic warming accelerates, the risk of triggering large-scale methane releases from seabed reservoirs increases
⏭️ What's next: The international research team will return to Antarctica for a two-month expedition to further investigate the seep sites, aiming to measure methane flux and identify the drivers of seep formation
• Their findings will be crucial in informing future climate models and mitigation strategies
• Growing calls are expected for policymakers and scientists to integrate subsea methane risks into global climate assessments
💬 One quote: “They are amazing to study and understand, but one needs to be very aware of what they can do if provoked or underestimated.” — Andrew Thurber, marine biology professor, University of California, Santa Barbara
📈 One stat: The study identified more than 40 methane seeps in Antarctica’s Ross Sea—compared to just one previously known active seep in the region
