Which volcano caused the most infamous volcanic winter in history?

Mount Tambora’s 1815 eruption injected vast amounts of ash and sulfur compounds into the atmosphere. These aerosols reflected sunlight and helped cool global temperatures for months. The result was the notorious climatic disruption of 1816, remembered as the Year Without a Summer. Crop failures, food shortages, and unusual weather were reported in parts of Europe and North America. Tambora is one of the clearest examples of how a single volcanic eruption can affect the global climate.
