PETM

The PETM is the natural experiment that skeptics seek.

And remember that the PETM was a major increase in global temperatures caused by a major increase in atmospheric greenhouse gas concentrations.

I have no idea how you get that impression when the full name of the PETM is the “Paleocene-Eocene Thermal Maximum”.

The PETM is the closest natural analog which does not mean it matches the current circumstances exactly, that would be ludicrous! to the current addition of greenhouse gases to the atmosphere.

The PETM is the basic “real world” demonstration of the radiative forcing effect of LAGs that is repeatedly requested.

The PETM is a stunning example of carbon dioxide-induced global warming and stands in contrast to critics who argue that the Earth’s temperature is insensitive to increases in carbon dioxide, said Pagani.

I was under the impression that the idea that the cause of the PETM was a GHG excursion has been accepted science for some years, so I don’t know why you would expect this paper to dwell on that point.

This sudden warming event, called the Paleocene–Eocene Thermal Maximum (PETM), was one of the most notable climatic upheavals in Earth’s history.
