We saw yesterday how 19th explorers discovered that the Ross Ice Shelf receded by 30 miles in the 19thC.
To add to that picture, this study found that elephant seals migrated to the Victoria Land Coast in the Ross Sea about 8000 years ago, as the region became warmer, and stayed there till about 1000 years ago when sea ice returned.

Meanwhile another study shortly afterwards found evidence that the Ross Sea cooled significantly during the Little Ice Age:

This all indicates that modern glacier retreats are just part of a much longer climatic cycle.
One of the arguments against the claims of Catastrophic Anthropogenic Global Warming is that what ever it is that they are claiming, it probably happened before.
There is very little that is new under the sun.
It is why they fight so hard to erase it, with hockey sticks and proxies that “prove” it is warmer now than even the Holocene optimum despite endless physical evidence it was warmer back then.
They are religious but their faith in their beliefs is weak.
“It is why they fight so hard to erase it,”
Exactly.
How do they get to publish this stuff? It contradicts ‘the narrative’.
C’mon. We know that seals can be trained to clap and balance a ball on their nose, but they’re really not that smart. According to Michael Mann, they must have been mistaken.
They can’t play hockey with sticks!
Michael Mann is no doubt planning on an expedition to core into these seals to examine them internally and shut them up once and for all!
But the science is settled –
a ‘Distinguished Professor’ told us yrs ago there was no LIA, … & he had a bald head & a NoBalls Prize & numbers & big words & a picture with lines on & everything !!
l think it was very likely that the LIA affected both the NH and SH. As it looks like to me that low sun spot activity affected the jet stream right across the globe. l think it affects were felt more in the NH because there is much greater landmass there and that’s where the most people were to record its effects.
Here in the NH l think what’s key to understanding what was going on during the LIA. Was how the change in the jet stream forced high formation away from the Hadley cell area and to form further to the north over the eastern Pacific and north Atlantic. While also stalling the weather patterning so it was remaining over an area for longer periods in time. The current state of the jet stream is pointing me to the reasons how both these things could happen.
.
Along these lines, I recall that back in they day when Mann published his tortured data there was some chatter that perhaps the NH and SH were 180%deg; out of phase.
Yes l have heard that the LIA was confined to the NH. But the current state of the jet stream suggests to me that was wrong.
l think its because there is much more ocean in the SH. That any changes in the jet stream had less impact.
A lot of peer reviewed studies indicate the LIA was global. Go to CO2 Science web site.

It is well documented.
Jim King:
The Central England Instrumental Temperatures data set (1659-present) spans about one third of the LIA, and is probably representative of the full LIA.
All LIA temperature decreases within that period show complete correlation with volcanic eruptions around the globe, so all hemispheres would have been affected at the same time.

I was thinking that as I read the article.
I’m no climate scientist, or even just a climastrologist, but I once (ca. 2016) got irritated enough to write up a layman’s explanation for climate change, and yes, there definitely is a mechanism for 180 degree phases between the two hemispheres, something I believe is actually happenening right now (as it’s always been, after six years of “new data, I’ve only ever had to change spelling mistakes).
The pictures are real amateur, the prose is very unpoetic and I don’t hardly never give no references, but here you go:

8,000 years ago humans had only 12 years to save the planet.
And they did it! They threw away all their cars and electrical devices, everything that made living in the copper age worthwhile and returned to the Neolithic for the sake of the planet. Green neofascists expect no less sacrifice from us, today.
I loved the copper age, there were bright copper kettles and warm woolen mittens.
All my favorite things.
Ok that made me LMAO!!!!!!!!!!!!!!!
Well, from the current state of our State, I would say the blighters failed…
Seems to indicate that we’re dumber now than we were 8,000 years ago, anyway.
Oops more evidence the LIA wasn’t local?
The current understanding is not that the LIA was local, but that it was not a globally synchronous event. See, e.g., Neukom et al., 2019.

Last line of abstract
“This provides strong evidence that anthropogenic global warming is not only unparalleled in terms of absolute temperatures5, but also unprecedented in spatial consistency within the context of the past 2,000 years.”
Paper paywalled so it could be in there or references, but the ‘firm’ conclusion needs an explanation of how certain areas of ocean and land were left out. I see this too frequently in fisheries/ecological papers where the blame is put on something people did such as overfishing, wetland loss, climate change, etc. I once sat next to such a modeler during a ‘robust’ discussion who said something to a colleague like–“…well, it would still be due to people.”His fisheries models didn’t work out very well. Credibility is better when you separate the assessment from the (preferred) management.
“but also unprecedented in spatial consistency within the context of the past 2,000 years.”
If one believes that current warming is happening everywhere and is consistent with with the Global Average Temperature, one should look more closely at what is occuring in the globe. There are currently regions with little to no warming and even cooling when regional temperatures are calculated. That should lead one to the conclusion that GAT is not an accurate description of temperature at any location.
1000 years ago was during the Oort solar minimum, when the Arctic was warming. The polar see-saw effect in action.
