Hi, Josh -
I'll take up your comments later, but first, I mentioned the simple
use of ground-based SO2 emissions as a practical way to fight hydrate
releases for now, which should be more or less socially acceptable and
could possibly therefore be undertaken very soon as suggested by John
Nissen
Hi Nathan,
What concerns me is that the argument you present is based on
conjecture. Your conjecture may be correct, I have no idea, and
informed speculation is entirely appropriate for this type of forum,
but some are now asking policy-makers to make deployment decisions in
the absence of hard,
Hi, Josh –
I think one is seeing what you’d expect to be able to see: rather
large perturbations from background levels right around large plumes,
by as much as ~100ppb, I believe, and then progressively smaller
deviations from background when considering larger regions, with the
whole arctic sea
Hi, John list –
Until now, my view has generally been that we should try like crazy to
get
some rapid SLCF declines, by promoting a separate near-term-focused
emissions strategy,
in an attempt to blunt accelerating arctic methane emissions, while at
the same time
researching geoengineering
Nathan, John, et al.,
One aspect of the methane issue bothers me in particular: is there
evidence indicating a significant increase in the rate of methane
release in the ESAS over the past decade? Anecdotal evidence from the
most recent Russian expedition suggests an increased rate of release,
Hi Folks,
If you go back to the April and look at the weather in the Siberian region,
you will see that a large warm air mass sat above Siberia for some time. It
appeared to me that this early warming of the land would generate early
warm river waters infusing into the down current hydrate
Hi Michael,
I am chair of the recently formed Arctic Methane Emergency Group and we
launched our report in the form of a brochure at the AGU last week [1], as
reported in the Independent [2] and New Scientist [3]. The Russians
researching the East Siberian Arctic Shelf (ESAS) are well aware of
It's interesting how the methane hotspots in the map
accompanying the article seem mostly around river mouths
could this be utilized in conceptualizing remedies?
I remember a Shakova paper talking about the role of riverine flow
in terms of breaking up winter icebut there must be other
Just checking in Shakhova, she mentions that what she calls
flaw polynyas - the areas of open water in winter -
have quintupled in the last two decades, and now cover an area =
to all thermokarst lakes in summer. It's strongly driven by riverine
flow,
so, while the map for the article is very
