That's true enough. The key point, though, is that the cold would have come at a typical rate. Typical being extremely slow, by human standards. We would have had many generations to prepare for it.
There is growing agreement that what we are facing is going to happen very quickly, even by human standards.
- kaybe 10y agoThere is research that hints that a very quick onset might be possible. It's even be suggested that it can happen in months. [1] (I tried to find the corresponding paper but could only dig up a conference talk abstract.) The studies I found all used lake sediments in Irish lakes, so it's somewhat local and not conclusive yet imho. Still, it seems to be a surprisingly fast change in the data. (I was surprised; I didn't know.) Do you have a source for your point? It looks like a more extensive literature review is needed to answer this question since the answer is not on the surface. Or my google-fu is just weak today. On the other hand I also found research stating that the next glacial period might be a few 10,000 years off, so there's that.

- Diederich 10y agoI over-stated it. Like you, I've run into a couple of mentions over the past half year, but I don't have them handy.
