The average temperature wasn’t much more than 10 degrees C above today’s, and those of you who have heard of the runaway hothouse Earth scenario may wonder why it didn’t happen then.
So the Sun was cooler, CO2 was more and magically we didn't get runaway global warming?
Meanwhile, Zeke Hausfather, an IPCC climate scientist, has this to say -
"Hausfather argued that RCP 8.5 had been used by some experts, policymakers, and the media as something else entirely: as a likely 'business as usual' outcome. The worst-case scenario has been blown out of proportion as the most probable. "
Runaway global warming died at the hands of an IPCC climate scientist. RCP8.5 is highly improbable if not impossible; we don't have the fossil fuel to achieve that. That's why a transition to a reliable power supply is imperative. The only candidate so far is nuclear.

A major factor was that the Sun was cooler, and the planet’s orbital cycles were also different.
You have a time machine secreted in your basement? Theories abound. Proof not so much.
