On that point the geological evidence also shows the entire planet surface was once a molten hot mess, a recently formed rough ball made by collision and accretion.
None of which has to do with our human actions tipping the recent climate stability that cradled the formation of what currently passes for civilization.
It was also during this time that glaciers covered half of North America and most of Canada, which retreated and then came back again.
Yet, we act in some our media as if the knowledge of these events is suddenly novel, and that the trend of de-glaciation is somehow fresh. That the climatic reversion to the mean has just emerged
Saying that we need to replace a climate based timeline for a geological one is an order of magnitude of hyperbole.
Please, continue hiding the Medieval Warm Period and the Piri Reis Map and other things when it is convenient.
This "medieval warm period" that doesn't look anywhere close to what we're going through ?
And yes earth has been much colder and much warmer, so what ?
Please, open a book and lok at the scale of things
Southern Greenland, England, Russian, and Norway were all growing wine grapes during the medieval warm period. Some people claim the medieval warm period was regional, but this seems to be misstated - 55th parallel north across the world. Wine was being made in England as far north as York, and in the Americas, in Southern Ontario.
This calls into question the "regionalism" of the Medieval Warm Period.
One of the biggest reasons that the MWP is called into question is because the Climate Models don't have a good understanding of why, and we think it may have had a lower CO2 amount than today (although ice core drilling has numerous scientific problems)
A simple response to that is a graph of glaciation cycles https://opentextbc.ca/geology/chapter/16-1-glacial-periods-i...
In respect to CO2 https://mashable.com/article/co2-earth-history-climate-chang... or any longterm measurement of CO2 levels, however, speaking from a scientific perspective there is a great deal incorrect with current processes of measuring CO2 levels from ancient ice cores.
During the Last Glacial Maximum, many plants showed evidence of CO2 starvation also, which is part of the reason why desertification increased so much during the LGM.

I don't know on the downvotes question.
Exactly how many of the 22 full-length books and 700+ papers by Alfred Russel Wallace have you read though?
They're packed with meticilous observations direct from decades of field work on both sides of what is now known as the Wallace line.
Wallace had a better grasp on evolution than Darwin.
