from https://en.wikipedia.org/wiki/Arctic_methane_emissions https://en.wikipedia.org/wiki/Arctic_methane_emissions :
The Permian–Triassic extinction event (the Great Dying) may have been caused by release of methane from clathrates. An estimated 52% of marine genus became extinct, representing 96% of all marine species.
- Kinrany 6y agoCould we just replace the ice with concrete (before it thaws)?

- randycupertino 6y agoIs there an estimated timeframe on approximately when this will happen?
- irrational 6y agoIsn’t it already happening? Is that what is creating the huge methane explosions and craters in Siberia?
- samiru 6y agoYes. Check the Yamal Peninsula in Google Maps and you realize this kind of cratering is a process that has been going on for thousands of years (since the ice age really!).
- knowaveragejoe 6y agoThe scary part is that it's accelerating in on a timescale that's relevant to our needs as a species.

- omgwtfbyobbq 6y agoI think the largest deposits would take thousands of years to be affected, but there are shallow deposits that could be released, especially those near glaciers, where the glacier melting allows the nearby seabed to rise. https://en.m.wikipedia.org/wiki/Clathrate_gun_hypothesis https://en.m.wikipedia.org/wiki/Clathrate_gun_hypothesis

- adrianN 6y ago1% of the carbon stored in the permafrost is roughly as much a all of humanity is currently emitting per year. It's a lot. Permafrost thawing is an important tipping point in the climate system.
