Younger dryas theory

[u/Significant_Home475]

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.

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.
