alt Hacker NewsThat does not look very reliable to me, because that implies certain things are only affected by ambient temperature.
Btw, Can you tell me how ancient temperature is measured from ice cores? My lookup only says we can detect atmospheric composition, and not temperatures from the ice cores.

Air bubbles from ancient atmosphere caught in ice -> historic CO2 levels -> historic average global temps.
This is fairly 1:1 linkage, and the Earth-heating effect of atmospheric CO2 was established in what, early 20th century or so?

It seems like you're on the trajectory to refuting all historical measurements altogether. In that case, I can't help you. Good luck. I suggest the philosophy of Last Tuesdayism, it may interest you.
