Not within the history that we can reasonably determine data from. Other than perhaps asteroid strikes, which probably is not a scenario we want to reenact.
Now if you want to argue that the ways they determine prehistoric temperature are inadequate I disagree but that’s at least possible. We could have some fundamental misunderstanding about how to figure out temperature that far back that is throwing things off. There’s a significant amount of corroborating evidence that we’re right, but let’s say we aren’t.
We know, pretty damn well, how much CO2 and other GH gasses we are pumping out.
We also know, pretty damn well, what those gasses do. We can compare the ability of CO2 to absorb heat versus other atmospheric gasses.
I don’t really think either of those things are reasonably arguable. And I don’t think you need much more than those two things to realize that there is a problem.
