Planet-heating methane is escaping from cracks in the Antarctic seabed as the region warms

1. Planet-heating methane is [escaping from cracks in the Antarctic seabed](https://www.cnn.com/2025/10/10/climate/methane-seeps-antarctica?utm_medium=social&utm_campaign=missions&utm_source=reddit) as the region warms, with new seeps being discovered at an “astonishing rate,” scientists have found, raising fears that future global warming predictions may have been underestimated.

   Huge amounts of methane lie in reservoirs that have formed over millennia beneath the seafloor around the world. This invisible, climate-polluting gas can escape into the water through fissures in the sea floor, often revealing itself with a stream of bubbles weaving their way up to the ocean surface.

   Relatively little is known about these underwater seeps, how they work, how many there are, and how much methane reaches the atmosphere versus how much is eaten by methane-munching microbes living beneath the ocean. But scientists are keen to better understand them.

2. Im so tired man

3. The paper is [here](https://www.nature.com/articles/s41467-025-63404-3).

   This is fairly modest in comparison with other sources of methane right now.

4. The article says little is known about such seeps, but the most important thing is that all the way back in the 1990s permafrost and meth hydrates were being described as a “climate bomb“. We knew what to do to keep the bomb from going off back then, even if we did not have empirical measurements of the bomb’s scope

5. How about them positive feedback loops?
