How much methane is trapped in permafrost
WebApr 12, 2024 · The Arctic region is particularly vulnerable to abrupt climate change, as rising temperatures could trigger the release of large amounts of methane gas currently trapped in permafrost and undersea hydrates. This could cause a feedback loop where the release of methane leads to even more warming, leading to further methane release and so on.
