[Insert Your Own Catchy Title About Younger Dryas Here]
The hosts explain the Younger Dryas, a sudden return to near-ice age conditions about 12,900 years ago that interrupted the warming after the last glacial maximum. They describe what Earth was like during the preceding ice age and the brief warm Bølling-Allerød interstadial, how the Younger Dryas abruptly cooled the Northern Hemisphere while warming much of the Southern Hemisphere, and how this affected humans, megafauna, and early agriculture. They then walk through the main scientific hypotheses for what triggered the event and close by noting how its abrupt end opened into the Holocene, when agriculture and complex civilizations emerged.
