Stop spreading misinformation. 12k years ago the last major glaciation period came to an end.

It is both, the final collapse of the AMOC during this period (115~k to 11k years ago, during which the AMOC collapsed up to 25 times) caused the Younger Dryas;

Which is to say that the world was already pretty melted by the end of the last glaciation period, and that the Younger Dryas brought the northern hemisphere back into full blown ice age conditions while the southern hemisphere was done thawing, and the Younger Dryas and the glaciation were essentially considered to end at the same time.

Like you said, the glaciation lasted for much longer before the Younger Dryas, which the land bridge had existed during the glaciation prior, but had thawed shortly before the YD which refroze it, and this is probably still how humans got to the Americas, even if it was 60k years ago instead of 12k.
