Crazy in my mind to think about the system moving unimaginable amounts of energy around the planet and now we're changing it on a time scale shorter than what the planet usually sees. Reminds me of what I read about the Younger Dryas and how temperatures changed within centuries, if not decades.

I've heard some speculation that rapid climate change at that time could be the origin of global flood myths in so many cultures. Imagine you're just minding your own business and a glacial dam breaks. As far as you're concerned, you just experienced a global flood.

Melting so much ice in such a short time without some kind of a dam made of not-ice is physically unimaginable. Water has soooo much heat capacity it'd take hundreds of years unless we're talking about a yellowstone or deccan traps eruption under the south pole or something (haven't done the math, but I'm not sure if it'd be enough).

Something like this already happened relatively recently.

The water is already liquid. It’s just held back by an ice dam that fails. That’s what I meant by glacial dams.

The inter-glacial periods are 10K to 20K years. We are currently around 12000 years into it. "AI overview" keeps telling me human induced climate change may lengthen it, but the collapse of the AMOC might just end it.
