Ping!..........
doomed !!
doomed i tell you !!
we all are
Likely not. Looks like a pork project in the making.
Wouldn’t it have to warm FIRST in order to melt the permafrost and THEN release the CO2?
OK, so thawing permafrost released CO2.
Now... what caused the permafrost to thaw?
That’s what I thought, but I’m not a politically motivated scientist and the GSA did not put me up in a Holiday Inn express.
Those damn mammoths and T-rex driving SUVs back then!
I think the point is that orbital fluctuations caused the permafrost to begin melting and that released carbon in the form of methane and other gases that sped up the process in a catastrophic manner.....

Maybe they got their ‘model’ too close to a heating duct.
Two topics: (1) what caused the permafrost to warm and thaw? (2) just because your model fits THESE data, doesn’t mean your model is “true”.
In other words, it drives me nuts when these ‘scientists’ fail to THINK. If the PERMAfrost melted/thawed, then the earth must have ALREADY been warming. If the earth was ALREADY warming, then snow cover would be retreating as well, and the albedo (reflection of IR off snow cover) was decreasing as well.
It defies simple logic to “believe” the premise that CO2 rise precedes temp rise CAUSED by CO2 release. *IF* the PERMA frost is no longer permanent, and thus releasing CO2, then it MUST have been experiencing prior warming? RIIIIGGGHHHTTT?????
This very issue came up with ALGORE’s Inconvenient Truth — the WARMING in his two graph lines PRECEDED CO2 increase by 400 - 1000 YEARS. Geesh, not this crap again.
But, I bet they were well funded in this research ...

The new view is supported by calculations estimating interactions of variables such as greenhouse gas levels, changes in the Earth’s tilt and orbit, ancient distributions of vegetation, and carbon stored in rocks and in frozen soil.
Why do I doubt this math?
OK, so thawing permafrost released CO2. Now... what caused the permafrost to thaw?His High Asininity, The Great Priest of GloBull himself, Al Gore, tells us that "the relationship between carbon and temperature is complicated..."
That's right, Al baby. Complicated in that CO2 increases generally LAGGED temperature increases by as much as 800 years... throughout the entire history of life on earth.
Hmmmm... the Earth is closer to the Sun in WINTER, and further away in SUMMER (or at least for our hemisphere).
If permafrost releases methane gas when it thaws are those permafarts????
But it doesn’t stay that way.
The orbit of the earth alters periodically, slowly, over thousands of years, to where the opposite is true for a looooong time until it comes back to the beginning of the cycle............
Extreme enough to eventually allow the emergence and existence of a human species?
