Climate Change - 1816 - The Year Without a Summer
The climate can react to sudden shocks.
The weather in 1816 was very strange.
The weather in 1816 was very strange.
Spring arrived, but then everything seemed to turn backward, as cold temperatures returned.
The sky seemed permanently overcast.
The lack of sunlight became so severe that farmers lost their crops.
Food shortages were reported in Ireland, France, England, and the United States.
1816 became known as "The Year without a Summer" or "18-hundred-and-frozen-to-death".

It was over 100 years before anyone understood the reason for this weather disaster.
The eruption of an enormous volcano on a remote island in the Indian Ocean a year earlier had thrown enormous amounts of volcanic ash into the upper atmosphere.
The dust from Mount Tambora, which had erupted in early April 1815, had shrouded the globe.
With sunlight blocked, 1816 did not have a normal summer.
In Switzerland, the dismal summer of 1816 led to the writing of a famous story.
A group of writers, including Lord Byron, Percy Bysshe Shelley, and his future wife Mary, challenged each other to write dark tales, inspired by the gloomy and chilly weather.
During the miserable weather Mary Shelley wrote her classic novel Frankenstein.
This event was not unique.
Volcanic events can cool the Earth for a few years.
The large eruption of Mount Pinatubo caused a dip in global temperatures in the early 1990s:

In 1258 there was a European famine across many countries, and this is now linked to a major eruption in 1257 on Lombok in Indonesia - it has a much bigger sulphate peak in the ice cores than Tambora, so it was a bigger eruption.
An analysis of ice from a Swiss glacier by a team at the Climate Change Institute of The University of Maine (UM) in Orono has reported that a cataclysmic volcanic eruption in Iceland spewed ash across the Northern Hemisphere early in 536.
Two other massive eruptions followed, in 540 and 547. The repeated blows, followed by plague, plunged Europe into economic stagnation that lasted until 640.
Temperatures in the summer of 536 fell 1.5°C to 2.5°C, initiating the coldest decade in the past 2300 years. Snow fell that summer in China; crops failed; people starved. The Irish chronicles record "a failure of bread from the years 536–539."
