I have never seen a realistic demonstration that even a large volcano sub-sea could warm a region of water. Water has a large heat capacity is this in fact true, does anyone have a paper that covers this? What about all the moons like Europa that have liquid oceans all thanks to volcanic activity? |

I think the liquid is kept in this state by tidal flexing due to Jupiter's gravitational influence??
(Er.....got that from wiki)

You only have to look at heat distribution in the N Atlantic to 'need' an additional heat source for the warm water on the returning gyre's. diggingintheclay.wordpress.com/2011/08/25/effects-of-subsea-volcanic-heat/This guy has some referenced papers at the end but does an interesting analysis... |

Boxman Last year this time you were having a terribly cold summer. How has this year been? |

Those Icelanders are doing a pretty good job at kick ball too! Now we have a current as well?  |

Excerpt from WP article.
"The debate reprises, in a sense, what happened only last week when another paper suggested that Greenland’s melting hasn’t been large enough, at least not yet, to slow down overturning circulation in another key region where it occurs, the Labrador Sea."
Looking at Greenland temperatures for the past two months, I doubt whether any serious melting has occurred. Perhaps it will be found that net accumulation was the result of central icecap accumulation being less than offset by diminished peripheral melting.
Watching sea levels might be interesting as a gauge on planetary ice accumulation.
In a month's time, the sun will start to seriously head for the horizon, and net melting gets less and less likely.

The world is internally heated by nuclear decay, and tidal friction. where that energy emerges is generally controlled by crustal conductivity plus a number of point releases such as volcano's and hot springs.(are there others?)
What is the balance between these two and if the world comes out of a cool spell as it did 12Kyr ago how long does it take to re establish equilibrium so that the crusts thermal gradient is again regular. Where the land is and was.
The ocean is very cold at the bottom and the heat comes from within it must be a significant mobilizer of said energy to the surface. I have seen little written about this, actually nearly zero.

No Argo updates since June. Suppose there's something they don't want us to see? Or they have just locked it down until someone gets around to publishing something? Come January, if someone has a contact in the new administration, we could complain about people not distributing data collected with public funds. There doesn't appear to be anything new on climate4you. The following chart is a good depiction of what has happened to temperatures to 800 m in a cross section across the N Atlantic current.  |

The surface of the north atlantic hasn't been as cool this year, you think Mboy??
VERY interesting to see the subsurface temps and of course, who knows what has gone on under the surface....
More and more however, I'm looking east for signs of a cold wrather pattern for N Europe.... (still learning here 😉)
Blocking the westerly atlantic flow and allowing cold air to draw over us from siberia/Scandinavia is what really gives us a drop in temps. The polar vortex, stratospheric conditions and jetstream are all combining in some way to generate blocking conditions
For now, anyway, any westerly air is still way warmer then freezing and moisture laden so wet and windy (booooo!!)
Be interesting to see what happens next spring....
