Spanish scientists have discovered massive methane emissions from the Antarctic seabed, a potent greenhouse gas that could accelerate global warming, highlighting the environmental risks of thawing ice sheets and trapped methane hydrates.
A team of Spanish scientists aboard the Sarmiento de Gamboa vessel has made a groundbreaking discovery beneath Antarctica’s icy waters. The researchers detected significant emissions of methane, a potent greenhouse gas that is far more effective in trapping heat than carbon dioxide. These emissions, previously unknown to scientists, could have serious consequences for the planet’s climate.
The methane, which has accumulated on the seabed for approximately 20,000 years, originates from methane hydrates, a crystalline substance created by the decomposition of organic matter. Geologist Roger Urgeles from the Institute of Marine Sciences in Barcelona explained that these hydrates are comparable to ice, but they can ignite if exposed to the right conditions.
The scientists’ findings are particularly concerning given the ongoing effects of global warming in Antarctica, where temperatures have risen by over three degrees Celsius in just the past 50 years. The thinning of the Antarctic ice sheet is believed to be triggering the release of trapped methane. This phenomenon, known as postglacial rebound, could result in the rapid release of large amounts of methane from the seabed.
In the region around Antarctica, approximately 24 gigatons of carbon are estimated to be stored in methane hydrates—equivalent to the total emissions of humanity over the course of two years. This discovery highlights a potentially significant environmental threat, as the release of methane could accelerate climate change, raising global temperatures even further.
In addition to the methane threat, the researchers also identified instability in the marine sediments, which could lead to massive landslides along the continental slope. These landslides could trigger a tsunami, presenting a further danger to the environment and surrounding regions.
This finding underscores the urgent need for continued research on the environmental and geological changes taking place in polar regions. As the effects of climate change intensify, understanding the potential risks associated with thawing permafrost and methane emissions will be crucial for mitigating the long-term consequences on global ecosystems and human populations.
As Antarctica continues to experience rapid changes due to rising temperatures, the world must take note of this significant discovery and its implications for the future of our planet. The potential release of methane from the seabed adds a critical layer to the conversation surrounding climate change and the need for proactive action.
The Copernicus Climate Change Service (C3S) reports that March 2025 was the second-warmest globally and the warmest on record in Europe, signaling ongoing changes in global climate trends.
China's glaciers have shrunk by 26% since 1960 due to accelerating global warming, with thousands of glaciers disappearing. The rapid melt poses significant risks to freshwater availability and could intensify competition for resources, according to recent data and a UNESCO report.
Record greenhouse gas levels in 2024 have driven global temperatures to an all-time high, accelerating the loss of glaciers and sea ice, raising sea levels, and bringing the world closer to a key climate threshold, according to the World Meteorological Organization (WMO).
