Need a reference for terrestrial clathrates and how much they are dispersed.

You seem to be confusing permafrost which is under tundra and clathrates which are under the sea. There are many patents about methods of extracting clathrates, and both China and Japan have extracted them as experiment, article from 2017 states that China expects extracting clathrates from south china sea to become economically viable by 2025. Permafrost on the other hand doesn't contain any methane, it contains large amount of biomass which releases methane when decomposing. And it is already melting in many places.

There are clathrates in Arctic permafrost, and also biomass which will release CO2 and methane if it thaws for an extended time. In another answer I mention sea bed clathrates and the possibility of mining them,but it has so far proved impractical..

(Asked by: username_0 on 2019-08-15)

We can see that there are [large buildups of methane clathrates](https://en.wikipedia.org/wiki/Methane_clathrate#Methane_clathrates_and_climate_change) in permafrost regions.

Climate scientist James Hansen has [predicted](https://www.theguardian.com/environment/earth-insight/2013/jul/10/james-hansen-fossil-fuels-runaway-global-warming) that the release of the permafrost methane clathrates could cause runaway climate change.

We know that some have related the [Triassic Extinction event](https://en.wikipedia.org/wiki/Permian%E2%80%93Triassic_extinction_event) to the release of Permafrost Clathrates.

I know that there are various techniques to extract natural gas from shale and rock.

My question is: **Is it feasible to 'harvest' the Clathrates from the permafrost before they evaporate?**
