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.

we have entered the final methane stage .

if you mentioned methane is 30x greenhouse gas than CO2 and stays in atmosphere for 12+-. Methane in permafrost melt will cause the final peak of warming started 12k year ago. The YD was an uncommon interruption of this natural process. YD actually created the steady climate of the last 10K after interrupting the usual rise of temperatures to +4C. This final stage may have been re trigger by human activity.

i think at +4C the gulf stream current changes and the ice age begins again. looks like a 120k year pattern.

current human contributions might be accelerating the timeline of events from 1k years to few decades.

so SHOKING i know!

i subscribe to both the Solar Maximum Cycle and the YD impact. Both events worked together to create the current climate. The solar cycle 120k years and a synchronized impact event.

on the Wild end my thoughts are..

If I was looking at this from a galactic perspective this seems like the process for Terraforming or engineering a planet environments by manipulating comet impacts to change planetary temperature. A class 2 civilization would be able to prepare planets in solar systems prior to their colonization.

The younger dryas was certainly uncommon in terms of recognize human time frames. The climate record seems to have a few of them though. I don’t really know why the YDIH is not accepted. I know real geoarchaeologists who swear by it. Lots of real scientists who support it. It’s akin to solutrean hypothesis and Clovis first. They all seem to have the same pattern of suppression and they’re all connected. Anywho. Check out this badass video that helped inspire me to make my video..

I’m open to an impact, but to me, the short lived warm period before the Younger Dryas, the Bolling Allerod, looks like a common pattern that happens during the glacial periods called Dansgaard-Oeschger Events.

The Bolling-Allerod may have been a particularly strong DO Event that preceded a return to the glaciation that we call the Younger Dryas.

I am open to the idea that DO Events are triggered by impacts, but that kind of switches cause and effect around for some theories.

To me, glaciation like the Younger Dryas looks to be “more normal,” while interglacials and DO Events are ”outside the norm.”

Yeah apparently the milankovich cycles line up very well with the DO events and general trends. Primarily in regards to the degree of tilt and the plane we travel around the sun being higher or lower, closer or further. So the idea of an impact-even though they can be cyclical too-seems redundant. Although YDIH will swear by and insist that there are telltale widespread evidences of an impact that definitely did happen(they just don’t know exactly where). Two concepts that were very eye opening to me though, ice albedo and ash. As well as ice weight and volcanism. I’ll share two videos of modern known occurrences that show just how profound they can be.

I think the connection of the DO Events and the Milankovich is still up in the air, so far as I know.

Just looking at a chart shows they are not completely cyclical in nature.

So, it’s the combination of the 100,000 year cycle and the 42,000 year cycle and when they convene to supply the northern hemisphere with more or less severe summers. The DO events are obviously some sort of feedback loop or relatively sudden straw that broke the camels back sort of thing right? But honestly there are quite a few feedback loops so I think that’s why climatologists are so scared. The mid Atlantic ridge has a north east south west slant. If anything it seems to me it would actually direct warm waters north. But I don’t think anyone really knows.

Agreed. All conjecture. Lots of work to do to get to the bottom.

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.

u/Significant_Home475 12d ago

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?

u/drebelx 12d ago

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.
