"If their theory is correct, it would mean these types of exploding craters are rare and only form under specific geologic conditions, so there's no risk of something similar showing up in, say, downtown Manhattan."
"As the planet continues to warm, more craters will likely erupt. When this happens, it releases a highly potent greenhouse gas into the atmosphere, which in turn contributes to climate change."
"The colder nooks of the world, in places like Siberia and northern Canada, have a subsurface layer of soil called permafrost that's been permanently frozen for millennia."
"Concentrated amounts of the highly explosive greenhouse gas methane are trapped deep underground in the permafrost in ice-like solids called methane hydrates."
