Current climate change is happening at an incredibly fast rate compared to historical fluctuations. I don't think they are comparable. But the point is nobody knows for certain so when it comes to modifying our environment at a grand scale we should probably try to be conservative.

There were a lot of rather abrupt changes even during Holocene [1]. We do not understand what could have been triggers for those changes. Which really emphasizes that we do not know how the climate works and as a civilization should have being preparing for the worst.

This is not true at all. During the recent period known as the Younger Dryas average global temps changed about 5°C over a few decades and then did it again in the opposite direction 1000 years later.

The post-industrial period is so short it wouldn't even register on most historical proxies.
