The year 1816 is known as the Year Without a Summer (also the Poverty Year and Eighteen Hundred and Froze To Death) because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.72–1.26 °F).
Impact: Caused a volcanic winter in the summer that dropped temperatures to 33.8 degrees in some parts of the US.
Start date: Eruption occurred on 10 April 1815
Mount Tambora, or Tomboro, is an active stratovolcano in the northern part of Sumbawa, one of the Lesser Sunda Islands of Indonesia. It eruption was felt worldwide.
The last time this occurred was in 1465. Scientists aren’t sure which volcano erupted then. This one helped created a year of darkness.
The summer of 1816 was not like any summer people could remember. Snow fell in New England. Gloomy, cold rains fell throughout Europe. It was cold and stormy and dark – not at all like typical summer weather. Crops failed causing famine.
Red snow fell in Italy.
Jerusalem froze over.
It snowed in many parts of Northern Africa and India.
Ironically, crops failed in many places except the Southern United States. The global food shortages made the southern planters very wealthy and helped ushered in what became known as “The Era of Good Feelings” 1815 – 1825.
Apparently something happened prior to Mount Tambora because there was a low solar activity between 1810-1823. The temperatures were below normal.
