I mean, it kind of needs time for there to be enough of a layer. You’re talking about a science that looks at the distant past and asking it to talk about at least the next several thousand years before they happen. It’s not the place to do it.

Something catastrophic could happen that makes the impact of the human-derived section of the layer we’re currently putting down miniscule by comparison. It’s unlikely, but the point is that we don’t know yet.

Geology isn’t really a good medium for activism of that particular variety.
