Volcanic winter

Volcanic winter refers to the significant drop in global temperatures that can occur after a large volcanic eruption. When a volcano erupts, it releases vast amounts of ash and sulfur dioxide into the atmosphere. These particles can block sunlight and reflect it away from Earth, leading to cooler temperatures. This cooling effect can last from months to years, disrupting weather patterns, affecting agriculture, and potentially leading to food shortages. Historical examples include the eruption of Mount Tambora in 1815, which caused the "Year Without a Summer" in 1816, impacting climate and agriculture around the world.
