  It would be strangely terrible if the beginning of humanities decline was prefaced with something known as the “Big Burp”.  The methane in the arctic is a super green house gas, and if the facts are correct, it is going to over salt our soup sooner than later.

“Wadhams puts to rest the common criticism by many in the scientific community that say not to worry about ESAS starting a bout of dangerous runaway global warming (RGW) because subsea methane deposits oxidize and dissolve in the seawater as released and never make it into the upper atmosphere, to wit: “The East Siberian Arctic Shelf is exceptionally shallow — more than 75 per cent of its entire area of 2.1 million square kilometres is shallower than 40 metres — so most of the methane gas avoids oxidation in the water column and is released into the atmosphere.” (Wadhams, pg. 123)

With ESAS getting more and more active as of recent, it is important to evaluate the risks of further breakout. For example, Wadhams says that Natalia Shakova, the leading expert on ESAS, believes it contains up to 700 GT of CH4. The risk is rapid release, a big burp of 8% of the deposit or 50GT, which, in turn, would crank up worldwide temperatures by 0.6°C over two years. This would have an extremely negative impact on the overall global climate system with unknown but likely horrific results as temps crank up to, or beyond, the IPCC danger zone of 2°C much sooner than anybody expects. Wadhams believes this is society’s biggest climate threat because at 2°C above pre-industrial crop yields start going down, very rapidly. An ESAS big burp would do the job.

The risk of an ESAS methane big burp alone should be enough of a threat to motivate global governments to call an emergency meeting at the UN to do whatever it takes to halt excessive greenhouse gas emissions on a worldwide basis as soon as possible.”

What a time to be alive!
