Count me in as a consultant. I’m not highly qualified, but I can give a highly qualified opinion on any subject.
The sea surface temperatures in these regions in August is normally 6C to 12C. So, 10C to 18C would be 4C to 6C warmer than today.
Some of these newer isotopes like the Uk37 used in this study seem to be showing warmer temperatures than other isotopes do.
This chart should show a temperature history over 67 million years which are very similar to the locations chosen for this study.
3 million years ago +1.0C to +2.0C and 55 million years ago +12.0C. If we applied the same ratios as this study, temperatures would be closing in on 100C 55 million years ago. So they need to recalibrate these isotopes.

This makes about the fourth piece I’ve seen based on these old proxies recently revealed where each new twist is a caution against repeating what took place years before there was any industrial activity or other source of man-made contribution.
Considering how hard the CRU worked to bury the warm period in the hockey Stick when there were men here in small number, all this noise seems to be just noise.
If this crap can happen without men around to stop it then, they must be imaging that we can forestall it now.
How ‘cool’ is that!?
The ocean levels were higher and there was a greater current moving warm water into the Arctic.
One theory is that due to North America's tectonic plate moving further North this has blocked the flow of that warm water which then plunged the Earth into a very long ice age.
Until the plate rotates a different direction, North America will continue to move North and further reduce the flow of warmer water into the Arctic.
My simplistic, but most likely accurate estimation is that it's going to get colder for a very long time.
I have no disagreements with what you said.

Thanks decimon. It's a little late this week to post a bunch of GGG topics, and I'm about to go to bed, AND tomorrow is spoken for, hmm, guess it'll be easy to do the Digest on Saturday. :') |

I think the complaint is about summer sea ice. Your picture are for December. Do you have anything for August? or July?
I seem to recall that about 3 million years ago was when the two hemispheres became connected by the isthmus of Panama, which caused major changes in ocean circulation and temperature distribution.
I was there. Horrible, horrible thing ~ just a peaceful middle-class school of sharks and next thing you know we were separated into two species ~ and it took forever to swim around Tierra del Fuego to meet up with old friends (and kissing cousins of course).
So warmer temperatures in the Arctic are or have been the norm? So what is the cause of the earlier warm periods?
Blame Panama for the earlier warm period.
Most scientists think this happened when the isthmus of Panama closed blocking global ocean currents.
So, the pattern is unlikely to break until plate tectonics breaks up the North/South America land mass.
Aren't geologists supposed to know this stuff?
The North American deal is more recent ~ 3 million years or so ~ and it moved into position to support year round ice and also to restrict the flow of warmer water into the Arctic ocean basin.
This lowered aggregate Ocean levels ~ and could have "cooled things down". The Ice Age started up 2.5 million years later ~
It's interesting the opening of the Straits of Gibraltar came just before the Pliocene Warm. Any connection?
North America rotated to begin enclosing the Arctic, and when that's done we're back to Snowball Earth where there really isn't any circulation of water currents between the equator and the poles.
The Leftwingtards will undoubtedly object to the use of nuclear energy to "restore circulation" claiming that this will disturb the ecological balance (of that time).
“The Cloud Mystery” on YouTube explains climate change with cosmic rays. I find it very believable. Actual experiments and real numbers, not “massaged” statistics.
Also check the book “The Chilling Stars” by Henryk Svenmark. Svenmark is the scientist featured in the documentary “The Cloud Mystery.”
