Keep in mind that the earliest great ape is about 7 million years old, the earliest homo is about 2.8 million years old, and the earliest Homosapien is 300,000 years old. Our whole existence was basically during the “very low base”.
One of the things I almost never see mentioned in the various climate debates is the observation that Earth is historically on the cooler side and is rising from that very low base.
The planet has historically gone through multiple cycles of not having polar ice caps and then having them again, etc. Over millions of years. There's been a really long-term feedback loop there.
I'm not a climate scientist by any stretch, but I just find that general omission in public discussions around it to be interesting.
