Update on methane emissions

Methane emissions in the Arctic - 08/17



This is methane at 500 hP which I believe corresponds with 10,000 feet over much of the Arctic.

This does not seem to be where the methane is coming from.


Arctic Methane 08 17 2018

The brown area, around 1860 ppb, is over the East Siberian Sea to the Beaufort Sea. It is over open water. The methane over the Laptev Sea has subsided.

What is happening in the Arctic Ocean is extremely important because of the huge amount of methane stored there.

WHAT A MASS OF PINK! (As well as Red.)


We have evidence of strong methane flow from north of Siberia (Laptev Sea and Eastern Siberian Sea).

How strong of a release we will not know for a while, but there are a lot of people who are frightened. I do not blame them.

I have been saying that I doubt that we will get a 50 Gigaton release of methane from Siberian Arctic Waters as Natalia warned. I said that because I believe it will be released as layers of the permafrost melt

If I am wrong I will have no problem admitting it, but I still doubt that a massive release like that is going to happen. Perhaps 20 Gigatons in ten to twenty years. That, I could agree to, but not 50 Gigatons in a short span of time
