Siberian Yedoma region:
1. permafrost melt beyond control
2. self-amplifying process
3. warming now hitting 3°C to 6°C
4. major methane release inevitable
5. 40 gigaton carbon-pulse danger
6. 'the melting of Yedoma is a tipping point: once it starts, there may be no stopping it'

from July 2013:
'A large region called the Yedoma could undergo runaway decomposition once it starts to melt. This is because elevated temperatures cause microbes in the soil to decompose, which causes heat, which creates a self-amplifying process.'

Analysis led by the UK's Met Office recognised the 'plausibility of catastrophic carbon releases from Arctic permafrost thawing of between 50-100 Gt this century, with a 40 Gt carbon release from the Siberian Yedoma region possible over four decades'.

Yedoma regions contain 327 - 466 billion tons of carbon:
'Were it all released into the atmosphere, that would amount to more than half of all human-caused emissions from greenhouse gases and deforestation between 1750 and 2011'

⚠️CO2 emission alone is greater than that pumped out by 1 million automobiles.
Methane is so powerful a greenhouse gas that the forcing provided by 4 megaton emission is nearly twice that.

⚠️ IPCC still omits abrupt thaw emissions:

⚠️ Permafrost has been rapidly thawing because Siberia is warming up faster than almost anywhere else on Earth ('more than 3C since preindustrial times'):

⚠️ 'it is becoming clear Earth is entering a shift in state of the atmosphere-ocean system associated with destructive climate tipping points. As Arctic permafrost is thawing an analogy with geological methane-release events...is becoming more likely.'

Yedoma: once it starts, there may be no stopping it:
