So a little bit of context to your facts, you forgot to mention that the rate of change in CO2 levels and global temperatures in modern times is on the order of 1,000 times faster than throughout the planet's history.
That’s not really true. You’re talking about 1.1 degrees C in almost 200 years and the Younger Dryas warming was much faster than that.
From Britanica.com: A second abrupt climatic warming event, approximately 11,600 years ago, marked the end of the Younger Dryas and the beginning of the Holocene Epoch (11,700 years ago to the present) and Earth’s modern climate. There is evidence that this warming was quite rapid; Greenland ice-core samples suggest that local temperatures increased by up to 10 °C (18 °F) in just a few decades.

CO2 is life.
If you want an example, look up at the moon. It’s carbon neutral.
Two look backs by different researchers:
CO2 is not a man-made issue.

The Younger Dryas was regional.
