Actually, we know for at least one industrial revolution in sumerian times a.k.a the beginning of the iron age. And we have a way to find for civilizations with larger impact by checking the isotopes locked in ice. This is the method for dating volcano eruptions and for tracking the produce of lead in antiquity.

Yet look at today, with climate change.

How many areas are seeing reliable ice layer formation? Stuff at the top (most recent) is melting away, too!

So... if the same thing happened before, Industrialization, co2, eventual collapse after warming, ice records may be unreliable...

Yes, but per the graph in the article, any earlier "industrial revolutions" and even the Roman Empire weren't even visible blips relative to the Western European industrial revolution.
