1816 simmer temperatur anomaly compared tae average temperatures frae 1971–2000

Location	Lesser Sunda Islands, Dutch East Indies 8°15′S 118°0′E / 8.250°S 118.000°E / -8.250; 118.000

Impact	Caused a volcanic winter that dropped temperaturs bi 0.4 tae 0.7 °C warldwide

The year 1816 is kent as the Year Withoot a Simmer (an aa the Poverty Year, the Simmer that Niver Wis, Year Thare Wis No Simmer, an Aichteen Hunder an Froze tae Daith)^[1] acause o severe climate abnormalities that caused average global temperaturs tae decrease bi 0.4–0.7 °C (0.7–1.3 °F).^[2] This resulted in major fuid shortages across the Northern Hemisphere.^[3]

Evidence suggests that the anomaly wis predominantly a volcanic winter event caused bi the massive 1815 eruption o Moont Tambora in the Dutch East Indies (the lairgest eruption in at least 1,300 years efter the extreme wather events o 535–536), aiblins plus the 1814 eruption o Mayon in the Philippines. The Yird haed awready been in a centuries-lang period o global cuilin that stairtit in the 14t century. Kent the day as the Little Ice Age, it haed awready caused conseederable agricultural distress in Europe. The Little Ice Age's existin cuilin wis aggravatit bi the eruption o Tambora, that occurred in its concludin decades.^[4]
