Scientists have discovered over 40 methane seeps in the Ross Sea, Antarctica, at an “astonishing rate,” raising fears that global warming predictions may be too conservative. These underwater seeps release climate-polluting gas into the atmosphere, trapping around 80 times more heat than carbon dioxide.
A team of international scientists used various methods to find these seeps, including ship-based surveys and remotely operated vehicles. The findings were surprising, as many previously studied sites showed new methane releases. This suggests a “fundamental shift” in the region’s methane emissions.
Methane seeps are relatively common globally, but this is the first confirmed active one in Antarctica. Researchers are concerned that these seeps could rapidly transfer methane into the atmosphere, making them a source of planet-heating pollution not currently factored into climate change predictions.
The cause of the methane seeps in Antarctica remains unclear, but researchers suspect it may be linked to climate change. The discovery highlights the need for further research and analysis to understand these underwater phenomena.
The study’s authors warn that if humans continue to warm the planet, these seeps could become a major source of danger, making them an “epicenter of danger” rather than a natural laboratory.
