Year Without a Summer
From Wikipedia, the free encyclopedia

"Impact Caused a volcanic winter that dropped temperatures by 0.4 to
0.7 °C worldwide
The Year Without a Summer (also known as the Poverty Year, The Summer
that Never Was, Year There Was No Summer and Eighteen Hundred and
Froze to Death[1]) was 1816, in which severe summer climate
abnormalities caused average global temperatures to decrease by 0.4–
0.7 °C (0.7–1.3 °F),[2] resulting in major food shortages across the
Northern Hemisphere.[3][4] It is believed that the anomaly was caused
by a combination of a historic low in solar activity with a volcanic
winter event, the latter caused by a succession of major volcanic
eruptions capped by the 1815 eruption of Mount Tambora, in the Dutch
East Indies (Indonesia), the largest known eruption in over 1,300
years, which occurred during the concluding decades of the Little Ice
Age, potentially adding to the existing cooling that had been
periodically ongoing since 1350 AD..."
