Increase
in methane releases from NOAA (that always trims the info if it looks
too bad)
Methane
Release Rate at Barrow for those of you who do not think it is
increasing. This is from their In Situ data that NOAA always TRIMS.
As we have noted in the past, they love to cut off the higher values.
Never
the less, what they have charted is frightening if you know what a
rapidly increasing methane release rate portends. I know, because I
have been tracking it for the past few years.
I
am only interested in the two inclining lines. The flat line before
it only indicates that during those years there was no great rise in
Methane. Had I gone back 20 years earlier, you would see a definite
incline for that period, too.

Thawing Permafrost Poses Even Greater Climate Threat Than Previously Thought, Study Finds
20
July, 2017
Thawing
tundra may be allowing long-buried pockets of methane to be released
into the atmosphere, new research suggests. A study surveying the
Mackenzie Delta in Canada, published Wednesday in the journal
Scientific Reports, suggested that these methane "seeps" on
the tundra may be more problematic than previously thought.
The
study finds that 17 percent of methane emissions in the area came
from these seeps, despite emissions hotspots only covering one
percent of the tundra's surface area. The authors wrote that warming
will "increase emissions of geologic methane that is currently
still trapped under thick, continuous permafrost, as new emission
pathways open due to thawing permafrost."
"We
were a bit surprised … we saw these very strong emissions. It means
a very tiny fraction of the area produces quite a big share of the
estimated annual emissions," professor Torsten Sachs, one of the
researchers, told The Independent.
As
reported by Inside Climate News:
"This
is another methane source that has not been included so much in the
models," said the study's lead author, Katrin Kohnert, a climate
scientist at the GFZ German Research Centre for Geosciences in
Potsdam, Germany. "If, in other regions, the permafrost becomes
discontinuous, more areas will contribute geologic methane."
