The YouTube channel. I just finished Fingerprints of the Cosmos. Randal Carson delivers a campfire talk, pointing out the historically proven timeline of chaotic, drastic changes using geology and pointing out the instability of the climate because of things that happened To the planet, caused by direct and indirect consequences of, the theory goes, comets slamming into the sun. The way I get it, it's a pretty new idea that is an explanation for Why the sun has Coronal Mass Ejections. He's saying that helps explain the times of warming. The cooling that brought about the ice ages is also covered.
The artwork is really good. Whoever is doing that is quite the artist.

Understanding How the badlands came to be, and the Carolina Bays, the thousands of elliptical depressions in the Northeast, trying to figure out What triggered the end of the last ice age, it's worth the twenty Ish minutes.
If nothing else, watching the artwork develop in step with the story being told is pretty cool.
I hope you guys enjoy this.

A phrase to get familiar with is The Younger Dtook

Younger Dryas (YD, Greenland Stadial GS-1)[2] was a period in Earth's geologic history that occurred circa 12,900 to 11,700 years Before Present (BP).[3] It is primarily known for the sudden or "abrupt" cooling in the Northern Hemisphere, when the North Atlantic Ocean cooled and annual air temperatures decreased by ~3 °C (5.4 °F) over North America, 2–6 °C (3.6–10.8 °F) in Europe and up to 10 °C (18 °F) in Greenland, in a few decades.[4] Cooling in Greenland was particularly rapid, taking place over just 3 years or less.[1][5] At the same time, the Southern Hemisphere experienced warming.[4][6] This period ended as rapidly as it began, with dramatic warming over ~50 years, which transitioned the Earth from the glacial Pleistocene epoch into the current Holocene.[1]

Significant cooling in the Northern Hemisphere took place during the Younger Dryas, but there was also warming in the Southern Hemisphere. Precipitation had substantially decreased (brown) or increased (green) in many areas across the globe. Altogether, this indicates large changes in thermohaline circulation as the cause[1]


The Younger Dryas onset was not fully synchronized; in the tropics, the cooling was spread out over several centuries, and the same was true of the early-Holocene warming.[1] Even in the Northern Hemisphere, temperature change was highly seasonal, with much colder winters, cooler springs, yet no change or even slight warming during the summer.[7][8] Substantial changes in precipitation also took
