They are?
Those look highly correlated to me.
The more important bit here is that climate in the past has been influenced by the Milankovitch cycles which are changes in the Earth’s tilt, orbit, and other mechanisms. As temperatures rise it releases more CO2 from the oceans which increases temperatures even more.
The difference now is that CO2 increases are no longer in response to the Milankovitch cycles. We are increasing CO2 independent of this mechanism. This will necessarily capture more heat. This was established by Svante Arrhenius clear back in 1896:
If that were the case then the Earth would be a cinder. It isn’t. Heat gets out. Earth does find an equilibrium between heat in and heat out.
What determines that equilibrium is the height in the atmosphere where that heat is able to escape. Below this altitude heat is reabsorbed before it can escape, but there is a altitude at which the atmosphere is thin enough that heat can finally escape. The higher this altitude the more heat that is trapped below this layer. CO2 increases the altitude at which heat escapes which increases global temperatures. It’s the same concept for why the Sun shines.
This is the saturation myth. It’s false.
