s/historical/geological/ please.
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.

I checked out your link, maybe you know more.
I am hoping to find other graphs to dismiss these 2 graphs below:

Hi xwdv,
We have carefully reviewed your suggestion. Unfortunately there are no big mountains in Antarctica, just flat sheets of ice. So it is not really suitable for a ski resort. Might work for polar bear hunting tho.

The word climate is mentioned >= 14 times in the article, not including the references. It is clearly an article about climate. Despite our measuring the climate (NOT WEATHER) in 30 year increments, and despite our knowing that from a climate perspective, the Last Glacial Maximum was ~21k years ago and during this time the glaciation hit a maximum and sea levels dropped incredibly.
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.

Starting a timeline at 20k years ago when we were, or near to the peak of the Last Glacial Maximum is not only deceptive, and most of Canada was under the giant Laurentide & Cordilleran glaciers, as was much of Asia, is frankly unscientific and alarming.
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 can't see your first comment(it's flagged) to reply more. How many down votes does this take to get flagged like this?
When you talk millions you have a point, but it does not apply to modern humans. (That I can see). I think hockey sticks(in my lifetime) are really meaningful in 20,000 year graphs. There is a lot of money out there to poke holes in these 20K year graphs, so I am looking for this holes.
