Thar she blows

All you folks who were raised (or are still) in a church that actually reads the christian bible: remember when god promised not to destroy the world by flood again, but by fire?  (That's actually really evil, when you think about it.)  Promises made, promises kept. (Caveat: we're the god that's doing all the things ascribed to CG.)

Add this to your California and Australia fires:


Scientists have found evidence that frozen methane deposits in the Arctic Ocean – known as the “sleeping giants of the carbon cycle” – have started to be released over a large area of the continental slope off the East Siberian coast, the Guardian can reveal.

High levels of the potent greenhouse gas have been detected down to a depth of 350 metres in the Laptev Sea near Russia, prompting concern among researchers that a new climate feedback loop may have been triggered that could accelerate the pace of global heating.

[...]

Methane has a warming effect 80 times stronger than carbon dioxide over 20 years.

[...]

The international team onboard the Russian research ship R/V Akademik Keldysh said most of the bubbles were currently dissolving in the water but methane levels at the surface were four to eight times what would normally be expected and this was venting into the atmosphere.

“At this moment, there is unlikely to be any major impact on global warming, but the point is that this process has now been triggered."

[...]

The scientists – who are part of a multi-year International Shelf Study Expedition – stressed their findings were preliminary. The scale of methane releases will not be confirmed until they return, analyse the data and have their studies published in a peer-reviewed journal.

But the discovery of potentially destabilised slope frozen methane raises concerns that a new tipping point has been reached that could increase the speed of global heating.
