Ajouté : 2026-05-22

[00:00:00]In 1816, a seemingly ordinary year turned into the year without a summer, altering life across the northern hemisphere.

[00:00:09]The catalyst was a massive eruption of Mount Tambora in Indonesia, the largest volcanic eruption recorded in history.

[00:00:18]When Tambora exploded in April 1815, it spewed ash and sulfur dioxide into the atmosphere, leading to drastic climate anomalies the following year.

[00:00:29]This volcanic winter caused temperatures to drop significantly, leading to widespread crop failures and food shortages in North America and Europe.

[00:00:40]In New England, snow fell in June, while across the Atlantic, Europe experienced relentless rains.

[00:00:47]Cities faced riots over skyrocketing grain prices, and famine loomed over rural communities.

[00:00:54]Yet, the unusual summer spurred unexpected creativity and innovation.

[00:01:00]In Geneva, trapped indoors by rain, Mary Shelley conceived Frankenstein.

[00:01:07]The poor weather also led to the invention of the bicycle as a response to a shortage of horses, which had become too expensive to feed. The year without a summer demonstrated nature's power to disrupt human society, leading to adaptation, resilience, and unforeseen cultural shifts.
