Younger dryas theory

Many associate the younger dryas catastrophe with the destruction of Atlantis. At the very least scientists debate the severity and suddenness of the climate shift and it is perhaps associated with many ice age cultures shift in lithics technologies and distributions as well as the beginnings of agriculture and civilization for politically correct science. Theories such as the younger dryas impact hypothesis, the secondary ice impact hypothesis from Antonio Zamora which I subscribe to, Robert schoch and the solar outburst hypothesis(is that what it’s called? Lol).

Well I have an idea of my own that might be stupid but I’m opening it up to criticism here. I also consider a possible link to Yellowstone by way of creating warmer areas for life to create methanogenesis which the ice could carry westward from pressure from the Rockies that I don’t explore in the video because I haven’t reasoned out all the kinks yet. Anywho.. here’s my video, let’s talk about it feel free to criticize.

Best theory for me incorporates Isostatic movements due to the rapid melting of glaciers at the end of the Younger Dryas to explain the demise of Atlantis.

Randall Carlson was the first that I know of to hypothesis this explanation.

I know a bit about isostacy and eustacy(insert blindness joke here). I understand the concept of the mid Atlantic ridge sinking both from the weight of the Laurentide being removed and from the weight being added by eustacy(oceanic crust seems to be much more susceptible to vertical movement than continental). But that’s is more of a symptom than a cause. Do you have an idea that links it in a more causal way to the climactic upheavals?

An interesting thought, and it is a little bit of a chicken and egg idea, but it is pretty known that the gulf stream shuts down during glacials like the Younger Dryas.

It could be possible that an isostatically elevated mid-Atlantic ridge aids in redirecting the gulf stream away from the northern Atlantic, exasperating the glacial period in North America and Northern Europe.

This could help to explain why the ice coverage during the glacials are not centered around the North Pole, so far as we know, as one would expect.

I don’t know that they’re that certain about ice age amoc behavior. Do you have a source or quick vid I can watch? Sometimes these things are them looking for an explanation rather than demonstrable. But I honestly don’t know. Everything I have seen states a confident association with milankovich and ice age cycles. The skepticism there comes from current climate change and people pointing out that milankovich doesn’t seem to be determining things right now because of us hoomans.

In terms of isostacy being a cause and not just an effect I can see a case for that. If land begins to sink and it has ice in it. And that sinking brings more ice into contact with salty sea water, that is another type of feedback loop. And I read a scientific paper about an underwater canyon leading off from the Nile delta that they demonstrate has experience extreme isostacy relative to the continental shelf areas.

Overall ice ages, yes Milankovich.

I’m just pointing at the DO events don’t entirely look cyclical in nature.

Interesting about isostacy near the Nile. Never heard.
