Kevin, we're a relatively well-behaved group and I appreciate you letting us use this corner of your far-flung internet empire to chat about the impending death of the planet -- or not. I will say there are some very sharp individuals on this board and no, they don't all agree all the time, but we all learn from each other. Not too many places like this. Thanks!

I like the "All Gore" spelling, Sig! It sure seems that way! All Gore all the time!

dresi, If that Antarctic ice graph was a global temperature anomaly they'd say "we're all gonna die!"
Funny how they make great hubbub over one but ignore others...
(or claim that the ice "hockey stick" is caused by global warming)

But but but...its going to come back, theres a new warm pool developing in the Western pacific!! And I'm Lebron James. Lebron, welcome! Now that you're out of the high heat in Miami you can let us know how things are in Cleveland over the winter. I like your screen name: Anthony Violi. Very nice. Glad you're posting here -- your secret is safe with us.

Holy cow! Don't let Graywolf see this!uafcornerstone.net/arctic_lakes_july2014/New University of Alaska Fairbanks research indicates that arctic thermokarst lakes stabilize climate change by storing more greenhouse gases than they emit into the atmosphere. Countering a widely held view that thawing permafrost accelerates atmospheric warming, a study published this week in the scientific journal Nature suggests arctic thermokarst lakes are “net climate coolers” when observed over longer, millennial, time scales. “Until now, we’ve only thought of thermokarst lakes as positive contributors to climate warming,” says lead researcher Katey Walter Anthony, associate research professor at the UAF Institute of Northern Engineering. “It is true that they do warm climate by strong methane emissions when they first form, but on a longer-term scale, they switch to become climate coolers because they ultimately soak up more carbon from the atmosphere than they ever release.” Found in the Arctic and cold mountain regions, thermokarst lakes occur as permafrost thaws and creates surface depressions that fill with melted fresh water, converting what was previously frozen land into lakes. Researchers observed that roughly 5,000 years ago, thermokarst lakes in ice-rich regions of northern Siberia and Alaska began cooling, instead of warming the atmosphere. “While methane and carbon dioxide emissions following thaw lead to immediate radiative warming,” the authors write, “carbon uptake in peat-rich sediments occurs over millennial time scales.” Using published data from the circumpolar arctic, their own new field observations of Siberian permafrost and thermokarsts, radiocarbon dating, atmospheric modeling, and spatial analyses, the research team studied how thawing permafrost is affecting climate change and greenhouse gas emissions. Researchers found that “thermokarst basins switched from a net radiative warming to a net cooling climate effect about 5,000 years ago,” according to their article, published online today. They found that high rates of carbon accumulation in lake sediments were stimulated by several factors, including “thermokarst erosion and deposition of terrestrial organic matter, nutrient release from thawing permafrost that stimulated lake productivity, and by slow decomposition in cold, anoxic lake bottoms.” “These lakes are being fertilized by thawing yedoma permafrost,” explained co-author Miriam Jones, research geologist for the U.S. Geological Survey. Yedoma is a type of permafrost that is rich in organic material. “So mosses and other plants flourish in these lakes, leading to carbon uptake rates that are among the highest in the world, even compared to carbon-rich peatlands.” The study also revealed another major factor of this process: Researchers found that when the lakes drain, previously thawed organic-rich lake sediments refreeze. The new permafrost formation then stores a large amount of carbon processed in and under thermokarst lakes, as well as the peat that formed after lake drainage. Researchers note that the new carbon storage is not forever, since future warming will likely start rethawing some of the permafrost and release some of the carbon in it via microbial decomposition. Because roughly 30 percent of global permafrost carbon is concentrated within 7 percent of the permafrost region in Alaska, Canada and Siberia, this study’s findings also renew scientific interest in how carbon uptake by thermokarst lakes offsets greenhouse gas emissions. Through its data collection, the study expanded the circumpolar peat carbon pool estimate for permafrost regions by more than 50 percent. This international collaboration has received funding or support from the Alfred Wegener Institute, National Science Foundation, University of Alaska Fairbanks and U.S. Geological Survey. It also included researchers from the Far-East Branch, Russian Academy of Sciences; University of Minnesota; University of Florida; Max Planck Institute for Terrestrial Microbiology; and University of New Hampshire. THIS... calls for one of these...

Phydeaux, You will have to forgive Graywolf. He is a firm believer in CAGW, and can't wait everyone to die. So he can gloat. In the meantime, he consoles himself with AGW pron. Pictures of melting snowdrifts and such. I know, I know, that is the stupidest thing you've ever heard. Don't tell me, tell him. Here. This will make graywolf's day!

Sig et al, For no real reason I picked 4.2. Since any number is as likely as any other number at this point, I'm sticking with it.
I was dismayed that your poll didn't have 0 (zero, nada, zilch, bupkis, diddly squat, zip) so that others of "that persuasion" could participate. I guess they could simply participate via a write-in reply...
It didn't quite make zero as predicted last year as I recall...

Sig et al, Still here... work has me quite busy these days. Only time to lurk now and then. Cheers to all.
I (think) I can understand Graywolf's desire for an El Nino. As I recall the last big one in 1998 was great fodder for the "WE'RE ALL GONNA DIE!" crowd.
And Sig, I sure can understand your El Nino desires (minus the Chris Farley costume of course!).
I learn so much here. I want to say I think it was brought to my attention initially by Nautonnier that an El Nino is ultimately a cooling event.
So in the event of an El Nino, Graywolf gets his much-beloved global warming -- but only for a limited time before convection and radiation remove all that wonderful heat. Certainly no warm reminders of that 1998 El Nino remain today.
I guess it's kind of a "careful what you wish for" thing...

Graywolf, thank you for your double post. Graywolf, thank you for your double post.
I am not familiar with the source material, but I am interested in a short (or long) response regarding the thinking behind the expection that big El Ninos are expected to increase in frequency.
What is the proposed mechanism behind that? Can you elaborate?
Thank you. Thank you.

Maybe Sig could put a message in a bottle in his back yard in mid-Summer. Then, he could check it in mid-Winter. If there's snow on it... Presto! CAGW debunked. Sig is famous. He gets a Noble Prize (as opposed to Nobel). The world is saved along with countless humans. They erect a statue of Sig on the mall in DC. T'stat and Numerouno attend.

Well, glenn, I suspect a cold AMO, PDO and quiesent sun will likewise convince many others that the "CO2 does it all" argument doesn't hold up. (Not saying you believe that...) It will make life interesting, however... throttleup, I am not saying CO2 is not a player. But I think it is foolish to think it cannot be trumped by the same factors that have always driven our climate. Copy that...
