Why Some Frozen Lakes Catch Fire

Winter lakes, though seemingly lifeless, are teeming with microbial activity. Some microbes, like methanogens, convert carbon dioxide into methane, a flammable gas. This can lead to pockets of lake ice catching fire, a phenomenon used by scientists to study methane emissions. Research in these harsh environments is challenging but crucial, as climate change is reducing ice cover, potentially increasing methane release. Methane is a potent greenhouse gas, and its increased release could exacerbate global warming through a positive feedback loop.
