Just 20 years ago, few had heard of the Younger Dryas—a 1,300-year period of violent climate upheaval.
It ended 11,600 years ago with a sudden ice melt, a massive sea level rise, and the extinction of Earth’s great megafauna—all in a geological blink.
What triggered it? We still don’t know. But it was the moment the world we know… began.

Younger dry ass
Massive meteorite hits would do it
It wasn't just megafauna that went extinct. Lots of little guys died off as well.
It's very clear that interinterstadials occur with recurring consistency and a change in output from the Sun of 2% will change the earth surface between 40-60% very quickly. Core samples from the moon proved this theory. 😊
So even then America was number 1
Research The Carolina Bays . This is where the huge ice chunks landed. Elliptical, they show the direction they came from. The great lakes area. Large crater in NW Greenland dated the same time period. Or did I disturb your religious timeline.
Civilization growth then crash, then repeat
It has to do with a few factors the climatologist seem to conveniently forget. You have Sun cycles. You have changing magnetic poles and cycles here on the planet of volcanism and sometimes meteor hits ECT. To claim climate change is a manmade phenomenon is incredibly ignorant, arrogant, dishonest and in many cases insane bonkerville pseudoscience. We all agree. Don't like the smog. Wanna save the fishies. Like polar bears. I like polar bears. The whole issue like most left wing issues is manipulative. It's under the assumption that this is why government is needed and your liberties must be violated because after all. Storm A or event B or disaster C is unjust and must be solved and the only one who can solve it is government. Really both sides will find a way to take your liberty but the left and social ideas tend to be dominated by the democratic party in America.
Solar variability is the key. Sun sleeps, earth freezes, nice micronova! Ice melts. Rocks show the micronova. The trees and our climate shows our star is a classical long term variable. If you examine the evidence, you will see it too.
SUVs are clearly changing the weather. 😅
How will HAARP weather control affect this cycle ?
Man has absolutely nothing to do with this warming!
So is there a normal state of earth or average ? Cause the alternative doesn't sound fun.
The answer is 42 !
The planet killer! We had one season & Dinosaurs loved it. When the Moon arrived, it made it impossible for large animals that rely on a single season so, slowly more complex life came & slowly the Moon will wipe out life before it leaves. I was a Moon of the Sun like Mercury is, close to the same size & baked hard (Rings like a bell) That's what happened & I know it!
The man theyre afraid of. Says a lot !
Randall is an awesome researcher! He knows his craft very well!
I didn't realize humans were affecting the weather with carbon emissions way back then. That's sarcasm if you are not smart enough to figure it out.
Imagine we lived 11 thousand years ago. Ancient woke liberals would blame my cave fire for rapid climate change that melted glaciers 🤦
Look closer to the sun for answers to your climate questions.
CLIMATE CHANGE HAS BEEN HAPPENING FOR THOUSANDS OF YEARS.
More like the last 800 000 years, there has been large swings between glacial and interglacial periords. What drives these is Milankovitch cycles and glacial and freshwater interaction with the AMOC. The younger dryas was special in that there probably was a comet impact on the Laurentide ice sheet, leading to more rapid cooling and the extinction of the large NA fauna.
Discussed Y-D almost 30 years ago in college (probably herpetology/ichtheology)
Mother nature is best guess.
I think the weather reflectivity has the most to do with it. Almost like clockwork something happens every so often that keeps the sun from melting everything. I guess we're about due for another volcanic winter is the explanation your looking for.
I don't consider this as enormous climate change. Compared to other planets, we're looking good!
It could have something to do with our plants position in the galaxy that is constantly changing.
My uniformed brain says we are in between ice ages, duh huh!!. My opine is that the earth will continue to warm until the beginning point of the next ice age, then it will bounce about again with the interglacial and glacial environments and then go into snowball earth or something close to it again. Its a cycle, IE: natural. Have we contributed to the change, likely, but I nor anyone else can prove it beyond a shadow of doubt.
Santa Claus the beloved Scientist needs a man's haircut.
I think one must clarify the term "rapid" in geological terms. Carbon related warming due to fossil fuel burning by us humans cannot be compared to geologic time scales. Catastrophic phenomena e.g. impacts etc. excluded.
It's not your SUV's fault!
Mr Carlson is the most productive and consequential Scientist we have today….Thank you…!
Our ancestors 2,000,000 ago used plastic straws.
We’ve already been told
Solar micro-novas and earth magnetic field reduction?
"Must have been man made, carbon is bad we need to eliminate carbon." most liberals!
Pre-flood there was no rainbow The Bible says that was given as a promise. Doesn’t that suggest a heavy cloud in the upper atmosphere that blocked out a lot of the light? Couldn’t volcanoes in massive amount of atmospheric bombardment from space have caused a cloud like that that would last
I live right near Lake Erie and literally everytime I look at it, I think of how it must have been made. All the rolling hills in the surrounding area and massive rocks the size of cars liter the area.
Sir was yellow stone caldera there where it is now? Thank you 😮
Im just …swinging on a star😊
It fluuded every year4 …, 3hundred yrs .. Gilgamesh Epic..Noah, Biblical Floods, all same event..
Planet Nine, 100%.
Science, not capitalism. Refreshing
So if you have a glass of ice water and you let the ice melt does it not stay about the same water level…
The democrats cause climate change in order to raise a tax to make them a wealthy oligarchy
Must be that old diesel truck Bert keeps driving aeound in, that ol husk is a damn fossil i tell ya hwat.
From what I've all listened to, IMO….,. I've been drawn more to the idea, global weather shifts are due to us being in the middle of a "Pole Shift". Frozen water (Ice) actually decreases in….. Volume?……I believe….. When it melts and becomes liquid water, the water molecules get smaller. But with a "Pole Shift", it will cause a change in the gravitational pull of where the water may rise and fall to/from. Or…… Serious question here….. Am I just dumb and missing something?
How about geomagnetic excursions changing the way the earth absorbs the suns energy? During the height of one of these, our field strength is down considerably.
After having seen Randall many times and absorbing all this fascinating stuff. After asking why these quick dramatic changes. Sunbursts and more and less activities in combination with meteorites and vulcanic activity.🤔
