that all makes sense , so its like a heat sink only its
for carbon and life in general that existed in the lakes
before the lakes drained.

and the "ice box" effect locked it up inside the permafrost
and sediment.

that definitely was not something I had considered , Im
not sure what its impact has been on the overall climate
but could it really have a significant effect when considering
the amounts of CO2 that humans have released by burning fuels?

we haven't caused a rise in temperatures and we pump 1000 times the amount of CO2 into the atmosphere each year than volcanoes do.

as far as the locked up methane goes , if this permafrost
will melt enough to release some of the methane then maybe
that will stall the ice age for a while.



3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.

...yep; volcanoes are just part of the baseline variance; yet some new complication is afoot!

...and back on topic:
Alaska also has some record high temps, in the news today.
Though the July temperatures anywhere, in any given year, have nothing to do with proving (or disproving) climate change or global warming theory.

The scale of climate is too long (and variable) for "record" temperatures to serve as evidence for those. Nor is global warming theory based on observations about temperatures or any recent temperature trends. It’s just physics ...that informs climate change and global warming theory.

....Which is why I want to thank you for that neat link.

Here is the original source:
http://www.nature.com/nature/journal/v511/n7510/full/nature13560.html

...where they mention:
“Our estimate of about 160 petagrams [gigatonnes/Billions of Tons] of Holocene organic carbon in deep lake basins of Siberia and Alaska increases the circumpolar peat carbon pool estimate for permafrost regions by over 50 per cent.” ...fyi, that is equivalent to over 500 gigatonnes of CO2!


I have been looking for information on just this subject;
since I’m also advocating for building more soil,
instead of only cutting emissions
...as a solution to the greenhouse gas problem.

...and globally:

...equivalent to over 8,000 Billion Tons (Gt) of CO2 ...while we worry about emitting an extra 30-40 Gt each year

And that soil carbon is in flux too! Both naturally, and because of anthropogenic land use/land cover changes, soils and soil carbon have recently become significant players in the global carbon cycle.
Opportunities abound for offsetting our [relatively] puny problem with CO2 emissions.

Interesting article, but highlights the confusions that can arise as terms cross the Atlantic. Here, a ton is bigger than a tonne.

"Over the last two decades, about 295 billion tons (269 billion metric tons) of ice is melting each year on average because of human causes and about 130 billion tons (121 million metric tons) a year are melting because of natural causes, Marzeion calculated."

That's a pretty blaring typo. Someone might wanna let that writer know. Talk about adding confusion. 130 billion tons converts to 118 billion tonnes, not million.

The thing that gave me pause for thought was tons being smaller than tonnes; I didn't even notice the arithmetic or the typo.

I didn't notice the typo either (million/billion), but am familiar with the ton/tonne conversion.

Since 2.2 pounds is a kilo:

...a thousand kilos would be 2200 pounds.

So a metric ton (tonne) is 1000 kilograms

...or would that be 1000 kilogrammes? wink

On this side of the Atlantic a ton is 2,240 lbs. It's not often we have something bigger than the Americans have. laugh

...details, details....
1 kilo = 2.20462 pounds. But searching online:

"unit of weight in the avoirdupois system equal to 2,000 pounds (907.18 kg) in the United States (the short ton) and 2,240 pounds (1,016.05 kg) in Britain...."

Nothing is simple, eh?
===

"The tonne (British and SI; SI symbol: t) or metric ton (American) is a non-SI metric unit of mass equal to 1000 kilograms; it is thus equivalent to one megagram" -wikipedia
...so 2,204.62 pounds?

So a metric ton (tonne) is neither a short ton (American) nor a long ton [or imperial ton] (British), it seems. "A long ton is 20 hundredweight."

"In India’s Western Himalayas, changes in altitude are so dramatic and steep that alluvial grasslands, subtropical forests, conifers and alpine meadows lie stacked almost on top of each other, producing a spectacular range of vegetation. Now, the myriad plants that inhabit these mountains are migrating upwards because of climate change — and some are in danger of being lost before anyone has even recorded their existence."
