0南极海底甲烷渗漏引发科学家警觉
科学家近日在南极海底发现了数量远超预期、且不断增加的甲烷渗漏点，尤其集中在罗斯海（Ross Sea）区域。
这种肉眼不可见的气体是一种强效温室污染物，短期内的蓄热能力远高于二氧化碳，引发了科学界对全球变暖预测可能被低估的担忧。
研究人员在浅水区发现了超过 40 处新的渗漏点，这表明该地区的甲烷释放模式或已出现“根本性变化”——此前人们一直认为这种现象在南极极为罕见。
尽管目前尚不清楚确切原因，但科学家担心，气候变化可能正在促使海底甲烷储层释放，从而形成加速地球变暖的恶性循环。
Antarctic Seabed Methane Seeps Alarm Scientists
The provided text from CNN reports on the alarming discovery of methane seeps around the Antarctic seabed, which scientists are finding at an unexpected and increasing rate, particularly in the Ross Sea. This invisible gas is a potent climate pollutant, trapping significantly more heat than carbon dioxide in the short term, leading to concerns that global warming predictions may be underestimated. Researchers found over forty new seeps in shallow water, suggesting a potential "fundamental shift" in methane release in the region, which was previously thought to be rare. The article explains that while the exact cause is unclear, there is concern that climate change could be influencing the release of this methane from vast underwater reservoirs, creating a dangerous feedback loop that could further accelerate planetary warming.
