Randall Carlson has a series of YouTube videos up (about 17?) from a “class” he conducted some years ago. They vary in quality as some were well recorded and others had only audio, or nothing.
I’ve found them very interesting. His basic thesis is that there is a LOT of information pointing to a Younger Dryas impact field both in North America and around the world. (One of the big surprises for me was the South American mega-fauna extinction and impact sites).
I’m gong to post here his video about the huge number of woolly mammoth and rhino found in “muck” and permafrost largely in Siberia and other far north places. FWIW, my belief is that an impact into the ice field sent a giant Tsunami of ice slush over the north pole entombing these animals in very cold ice slush. Basically flash freezing them with chunks of 20 below ice in a froth of impact water.
Here’s his video. 42 minutes:
I think he does a pretty good job of showing the evidence for a major and catatrophic impact into the ice shield at the Younger Dryas. This is the 16th episode, so a lot of earlier ones are out there too.
IMHO, the Younger Dryas Impact Theory and those who Poo-Poo it is Yet Another Example of corrupted science where the “entrenched but wrong” use a variety of despicable methods to suppress the voices of those with better ideas. Lot of “attack the person” and not much of “examine the evidence”.
It is my belief also that such large impacts tend to set off a LOT of volcanic events (often on the other side of the planet due to refocusing the energy as it rounds the planet – antipodal focusing) so we end up with endless bickering about “impact vs volcanic” when the reality is “impact AND volcanic”.
Last time I brought up the impact event, on a challenge point, I’d said I didn’t know of any fires then. I did some quick looking into it, and in fact there IS a lot of evidence for some kind of global scale fire events as forest were ignited and burned. I’ve not done a decent enough dive on it to say anything beyond that, but it does look like it was “impact and fire”.
So it looks like we’d warmed out of the Ice Age Glacial, then got a major impact field over North America, South America, parts of Europe, and perhaps into the Pacific causing tsunami. Then a giant ice slush wave over the pole into Siberia, and a massive outbreak of forest fires. Then a big plunge back into the Glacial as the fires burned out. Talk abut your catastrophe.
This is coincident in time with the 12,000 – 14000 year ago evidence for a significant human civilization that collapsed and only recovered thousands of years later with the start of the Egyptian Empire history.
In short: We ought to be much more worried about stopping giant rocks from space than about burning oil.
FWIW, I have a lot of “things that piled up” in my posting ideas bucket, so I’m going to try to knock out a bunch of them without a lot of analysis and commentary, just so I can reduce the queue to something manageable.
