In short
Around 10900 BCE, the Younger Dryas—a sudden return to ice-age conditions lasting roughly 1,200 years—plunged the Northern Hemisphere into cold, drought, and widespread famine. As glaciers readvanced and temperatures dropped by up to 15°C in some regions, human populations that had begun settling into agricultural life faced mass starvation, forcing migrations and upending the early trajectory of civilization.
How it unfolded.
The five-minute version
What actually happened.
Famine has been a recurrent feature of life in the Indian subcontinent countries of India and Bangladesh, most commonly cited as a feature of British rule. Famines in India resulted in millions of deaths over the course of the 18th, 19th, and early 20th centuries. Famines in British India were severe enough to have a substantial impact on the long-term population growth of the country in the 19th and early 20th centuries.

Post-Younger Dryas expansion
Neolithic settlement and agriculture accelerate across the Fertile Crescent, Europe, and Asia. Population densities increase; permanent villages become established. The foundation for subsequent civilizations is laid.

Younger Dryas ends
Abrupt warming begins. Temperatures rise 7°C or more over 50 years in some regions. Glaciers retreat; moisture returns to formerly arid zones. The Holocene proper begins.

Natufian culture adjustments in the Levant
The Natufian, a proto-Neolithic culture in the Levant, shows signs of stress—reduced settlement size, dietary shifts, increased reliance on stored grains. Evidence suggests both adaptation and demographic pressure.

Younger Dryas onset (disputed trigger event)
Temperature begins sharp decline. Proponents of the Younger Dryas Impact Hypothesis cite evidence of impact around this time; other researchers argue for Heinrich Event 1—a collapse of Atlantic Meridional Overturning Circulation.
