New, better science provides new, better understanding. Is this truly a game-changer?

Undersea volcanoes may be impacting long-term climate change

Mid-ocean ridge eruptions as a climate valve
Maya Tolstoy
Abstract. Seafloor eruption rates and mantle melting fueling eruptions may be influenced by sea level and crustal loading cycles at scales from fortnightly to 100 kyr. Recent mid-ocean ridge eruptions occur primarily during neap tides and the first 6 months of the year, suggesting sensitivity to minor changes in tidal forcing and orbital eccentricity. An ~100 kyr periodicity in fast-spreading seafloor bathymetry and relatively low present-day eruption rates at a time of high sea level and decreasing orbital eccentricity suggest a longer-term sensitivity to sea level and orbital variations associated with Milankovitch cycles. Seafloor spreading is considered a small but steady contributor of CO2 to climate cycles on the 100 kyr time scale; however, this assumes a consistent short-term eruption rate. Pulsing of seafloor volcanic activity may feed back into climate cycles, possibly contributing to glacial/interglacial cycles, the abrupt end of ice ages, and dominance of the 100 kyr cycle.

Just wait till methane is released from the seafloor due to global warming. Thing will get real fast.
 
2008? Please don't continue this. Methane has been advanced as a boogie man for years. It's nothing. And the Siberian holes were explained long ago.

Feel free to play the ostrich in the room. There lots of science out there re the methane threat. Not saying CO3 isn't a threat as well.
 

From the article: "So little data is available from the Arctic Ocean that no scientists dare say with certainty whether the world is watching the fuse being lit on a marine methane time bomb." - or a natural event. They left that part out. This is all it takes for some to cue the hysteria in the absence of any real data.


the threat is not just from the sea floor but also the permafrost. This has never been observed before in Siberia

Mysterious Siberian hole likely due to methane buildup and release

This isn't a threat. It's a natural event. I would even bet there are some other things we haven't observed. Just a wild guess, of course.

Greetings, Jack. :2wave:

And if it turns out that undersea volcanoes are the culprit here, what plans does anyone have to stop them from erupting? :shock:

Don't worry Pg, we have experts working on a solution as we speak.

One lonely guy working on this supposedly catastrophic problem? It figures! The rest must be needed to keep the propaganda machine fine-tuned, I guess! :lamo:

Try mailbox again..
 
Why would you expect this to be a "game changer?" What's changed?
 
Another case of...

The AGU press release explains it pretty well, I think.

The AGU also issued a press release [link]

"Possibly more important than we thought" translates into "game changer," in your opinion?

Oh, wait. it wasn't your opinion in the first place.
 
What article and/or thread did you read?

Oh...all this "methane" stuff.

Heck, nobody can decide if CO2 is something we should or can do anything about and now people in this thread are going on about methane.

I guess the "sky is falling" thing is my way of describing this stuff. Kind of like the "global cooling", "running out of food", etc...chickens in the past 40 years or so.

But I like it.

" . . . These findings could change the way scientists think about how to model Earth’s climate’s past behavior and could influence how they predict the planet’s future climate, Tolstoy said. . . ."
