Great response to this on Rabett Run: David Appell said... My suggestion is calling it the "Rick Scott effect."

Hey- I'll try it.......when I'm in the mood and if I don't feel I'm participating in a food fight. If we're lucky, it might feel a bit like Christmas in the trenches in 1915

Seems to me that this subject has an intrinsically difficult relationship with the concept of banter. Those of us who are really concerned about the effect AGW will have on us and posterity will have difficulty mustering the lighthearted POV inherent in banter. I fear that those who seriously doubt that the topic is worthy of our concern probably won't come - I suppose I could be wrong about that but it doesn't seem logical. Those who have other (i.e. non-serious) reasons to express doubt will troll. However - I suppose that this might be a good place to exchange gallows humor.

Not sure, although it certainly should have disrupted some methane clathrate beds. The Storegga slide was followed by fairly rapid warming and sea level rise, featuring the flooding of Doggerland (i.e. most of what is now the North Sea) but I always thought that the proximate cause of warming of this period was due to the events that ended the Younger Dryas- i.e.the resumption of the North Atlantic thermohaline current. So the Storegga Slide may well have contributed to this warming, via methane release, but I don't know of any direct proof of it.

http://www.nature.com/news/gas-hydrates-in-arctic-are-shallowest-yet-found-1.11988 Maybe an explanation for those ridiculously high SSTs near the mouth of the MacKenzie last summer?

I came across this too......http://www.nature.com/nature/journal/v490/n7421/full/nature11528.html?WT.ec_id=NATURE-20121025 Since hydrates can exist at higher temps as long as they are deeper, then trajectory changes in very warm currents such as the GS certainly might bring large temperature increases to sea floor regions in the Atlantic that contain such hydrates. And the current changes in the Arctic might plausibly produce changes in the thermohaline dynamics of the GS capable of altering its course. Sigh......

Bumped for some truly crummy news: http://www.bbc.co.uk/news/science-environment-19410444 I sure hope this paper (the Nature paper that is the source of the article) turns out to be another case of Nature's famous "molecular memory" paper, where some people diluted a solution to nullity and claimed that the solvent "remembered" the solute.....................

It's an emotional thing, too. I for one will mourn the passing of the Karri tree in SW Australia. But what was the deal about "Walmart birds"? Doesn't he know that we killed off the passenger pigeon - the ultimate "Walmart bird"?

I suppose it was..........but telling us collectively that stopping AGW is not worth redirecting economic activity (especially when such redirection is an economic PLUS) is outrageously counter to the facts (in a rather Rush - ite way) - and did rather invite derision. Mea culpa then........I maintain that your opinion as stated is factually without support and logically flawed, but I take back implications that you are unfit to discuss the point. BTW - its "futile", not "feudal"

But please don't wipe out the world's economies!!!! It's bad enough already.... Blizzard, take some advice: Stick to forecasting local Wx You have a red tag - presumably you can do that well enough. But complaining about wind farms killing birds in a world where whole mountaintops are being removed to mine coal tells me that you'd better leave the "big picture" stuff to others. And I don't mean Rushbo.

Hi Terry, The heat may be less of an issue than the pressure.........see my post at Nevens.

The "blue ice" phenomenon is interesting - at first I though it was regional (limited to fast ice and kettle lakes in the Lena Delta region), then it became clear that much of the CAA has it as well. Lots of Greenland glaciers too. But look at the uploaded file of the Ob'/Taz estuaries as they melted recently (fair weather, 5/28 to 6/9). The ice starts as gray - turns white before melting and assumes a bluish cast only just before the final melt (last frame - Ob' only) So the blue ice does after all have an important regional component, which would favor the involvement of CH4 release (or the blooming of CH4 eating microbiota). I'd have thought the lower Ob' would have LOTS of CH4, though.

"These seeps were characterized by anomalously high methane fluxes, and in Alaska by ancient radiocarbon ages and stable isotope values that matched those of coal bed and thermogenic methane accumulations." This seems to be the money quote. The release of LIA era CH4 from the Greenland sites may not be of great consequence, since Greenland has not exactly been a compost heap for the past 500 years. However, they seem to have direct evidence that ancient CH4 is being released from melting permafrost in Alaska. Since there could be a very great deal of methanogenic C in/under that permafrost - and since the CH4 from those deposits may have been generating it and then trapping it for thousands of years, there would seem to be some cause for concern......
