but compares the increase in CO2 and the increase in temperatures over this period, compared to the contemporary period.
Also compares the technical means of obtaining accuracy stats from then to those of today.

You must not have read them well, the evidence all converges on
CO2 causes warming (and not the other way around)
https://skepticalscience.com/docs/Scien ... French.pdf
Knowing that man is only responsible for about 1.x% of greenhouse gases (excluding the half that is naturally reabsorbed) you can go against the laws of physics with words Izentrop, but not with facts it doesn't have the same success.
It is therefore the warming that causes the release of Co
2 of the seas, and not the other way around. You can experience it...
In the middle of summer, take an unopened bottle of sparkling water from the fridge, open it to release the pressure and close it by placing it in direct sunlight, and when it's really hot you reopen it and you'll see... fine if the Co
2 did not come out by increasing the pressure to the max... (well you can also try without opening the bottle at the start, but the pressure will only be stronger). Then you compare with a bottle that has remained cool... And there will be no excessive pressure because the pressure will not have risen!
Then you do the opposite, but immediately creating an unfavorable situation, you take an unopened bottle, but you don't open it to release a little pressure, and put it directly in the sun, after a few hours. .. In the hypothesis that you suggest, either:
- “
that it would not be the increase in temperature which would release the Co2" ...well the pressure in the bottle should remain constant... right...?
But I bet if it's very hot the bottle will even have increased in volume, the Co
2 released forcing the PET to warp, and if you open it carelessly, you might get a kick out of it, but if you put it back in the fridge, it'll be back to normal.
If the experiment works, it is the proof that it is the action of the temperatures which acts on the Co2 and not the reverse.

However, I usually say that anthropogenic warming should not be taken lightly, not being either a climato-thing, or a climato-thing... all studies must be pursued without a peremptory, dogmatic position, political or ideological and above all to stop the plundering of resources...
