Global Climate Anomaly
- When
- 1816
- Where
- Global climate anomaly, strongest in the Northern Hemisphere
- Part of
- Mount Tambora eruption
Sulfur release caused global cooling, leading to the Year Without a Summer in 1816. Northern Hemisphere temperatures dropped significantly during the summer of 1816.
The eruption released SO2 into the stratosphere, causing a global climate anomaly. During the Northern Hemisphere summer of 1816, temperatures there cooled by 0.53 °C. Countries in the Northern Hemisphere suffered extreme weather conditions, dubbed the Year Without a Summer. Evidence suggests the anomaly was predominantly a volcanic winter caused by the massive eruption of Mount Tambora in the Dutch East Indies (modern-day Indonesia) in April 1815.
