What is a volcanic winter?
VolcanoesClimate
Quick Answer
A volcanic winter is a period of cooler global or regional temperatures caused by volcanic ash and sulfur aerosols blocking sunlight.
The Full Story
Explosive eruptions can inject sulfur dioxide high into the stratosphere, where it forms sulfate aerosols that reflect sunlight. This can reduce surface temperatures for months or, in some cases, a few years. The 1815 Tambora eruption led to the “Year Without a Summer” in 1816, with widespread crop failures in parts of the Northern Hemisphere. Volcanic winter is a climate effect, not an actual winter season, and it depends on how much material reaches the stratosphere.
