The Threat of Methane
Methane is a powerful greenhouse gas. More powerful than CO2.
The short film, Last Hours, released only nine months ago, explains the dire threat of a “sudden and massive global warming” – should huge pockets of frozen methane, which are trapped under land and the ocean floor, thaw and escape into the Earth’s atmosphere.
Such an enormous release of methane would create a “runaway” greenhouse effect on our planet. It would be the point-of-no-return. You see, there is no known method or technology to deal with a catastrophic event of this kind.
Today, I read this article published in Daily Kos: Mysterious Siberian Crater Found at “End of the World” May Portend Methane Climate Catastrophe. The time remaining to deal with climate change may really be shorter than we think.
[Methane’s runaway greenhouse effect] is probably the biggest issue that we face. Sea level change is a big one, too, a very expensive one to manage. But the methane release from the Tundra, once that gets underway we reach a point where we lose the option of having an effective mitigation strategy.
We can always abandon the coastlines, but if we activate enough of a carbon reservoir in the terrestrial biosphere, that becomes unmanageable. That’s, unfortunately, a kind of Doomsday scenario that our trajectory is pointed to.
