Of the 4 documents you posted

2 were about condition in the Holocene period - 6000 years before the MWP

1 was pure gobbledygook

1 was in the right time but specified a rather small local event.

That's  why they renamed it climate change.  They want everything to change and call it progress. Except climate. Climate must not change. That is also progress.

And each showed the MWP. But I guess you can't read graphs. ;)

Thanks Lee but I thought the science is decided?
There is no further room for debate?

Nobel Prize in physics awarded to scientists
whose work warned the world of climate change


By Rob Picheta and Katie Hunt, CNN

Updated 1308 GMT (2108 HKT) October 5, 2021


(CNN)The Nobel Prize in physics has been awarded to scientists Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi, whose groundbreaking work over the past 60 years predicted climate change and decoded complex physical systems.
Manabe, 90, and Hasselmann, 89, were jointly honored for "the physical modelling of Earth's climate, quantifying variability and reliably predicting global warming," according to the news release from the Royal Swedish Academy of Sciences.
Both men carried out pioneering work in the 1960s and 1970s that sounded an early alarm on human-made climate change.

Italian physicist Parisi, 73, claimed the other half of the award, for "the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales."

The trio were announced as winners at a news conference Tuesday in Stockholm, Sweden.

Natural variability still has not been quantified. The cooling in Antarctica is said to be within natural variation, although at odds with the CO2 meme of it only causing warming.

I would think that we don't want climate change that we cause leading to millions of people dying is probably what you should be thinking about.

Who said that ?

How does that fit with a lot of variability but overall warming ?

That is CO2 theory petal.

"How Exactly Does Carbon Dioxide Cause Global Warming?"

https://news.climate.columbia.edu/2021/02/25/carbon-dioxide-cause-global-warming/

or skepsci

     

"How do we know more CO2 is causing warming?"

https://skepticalscience.com/empirical-evidence-for-co2-enhanced-greenhouse-effect.htm

Nothing at skepsci about CO2 causing cooling.

The IPCC says so.   ;)

"Mean temperatures and heat extremes have emerged above natural variability in almost all land regions with high confidence."

"Several impact-relevant changes have not yet emerged from the natural variability but will emerge sooner or later in this century depending on the emissions scenario (high
confidence). "

"It is likely that the proportion of intense tropical cyclones has increased over the last four decades and that this cannot be explained entirely by natural variability."

So how many millions have died so far? How many climate refugees?

Were they displace by climate or war?. Drought is not climate. Long periods of drought may be.

"In conclusion, there is simply no supporting evidence or physics behind the claim that the global warming over the past century could simply be attributed to internal variability."

https://skepticalscience.com/internal-variability.htm

But apparently it can explain cooling. ;)

Oh, because... climate models. ;D ;D ;D ;D

And just look at the 1930-1940s peak which has since disappeared.
