As per the above examples, while eruptions like [[Mount Unzen]] have caused deaths and local damage, the impact of the June 1991 eruption of [[Mount Pinatubo]] was seen globally.<ref name=":05"/> The eruptive columns reached heights of 40&nbsp;km and dumped 17 megatons of SO<sub>2</sub> into the lower [[stratosphere]].<ref name=":14">{{Cite web|title=Self|url=https://pubs.usgs.gov/pinatubo/self/|access-date=25 October 2024|publisher=United States Geological Survey}}</ref> The [[aerosol]]s that formed from the [[sulfur dioxide]] (SO<sub>2</sub>), [[carbon dioxide]] (CO<sub>2</sub>), and other [[Volcanic gas|gases]] dispersed around the world. The [[Sulfur dioxide|SO<sub>2</sub>]] in this cloud combined with water (both of volcanic and atmospheric origin) and formed [[sulfuric acid]], blocking a portion of the sunlight from reaching the [[troposphere]].<ref name=":05" /> This caused the global temperature to decrease by about 0.4&nbsp;°C (0.72&nbsp;°F) from 1992 to 1993. These [[aerosol]]s caused the [[ozone layer]] to reach the lowest concentrations recorded at that time.<ref name=":14" /> An eruption the size of Mount Pinatubo affected the weather for a few years; with warmer winters and cooler summers observed.<ref name=":14" />

A similar phenomenon occurred in the April 1815, the eruption of [[Mount Tambora]] on [[Sumbawa]] island in [[Indonesia]]. This eruption is recognized as the most powerful eruption in recorded history.<ref name=":05" /> Its eruption cloud lowered global temperatures as much as 0.4 to 0.7&nbsp;°C.<ref name=":2">{{Cite web|date=24 October 2024|title=This Day In History: Mount Tambora Explosively Erupts in 1815|url=https://www.nesdis.noaa.gov/news/day-history-mount-tambora-explosively-erupts-1815|access-date=25 October 2024|website=National Environmental Satellite, Data, and Information Service|language=en}}</ref> In the year following the eruption, most of the Northern Hemisphere experienced cooler temperatures during the summer. In the [[Northern Hemisphere|northern hemisphere]], 1816 was known as the "[[Year Without a Summer]]". The eruption caused crop failures, food shortages, and floods that killed over 100,000 people across Europe, Asia, and North America.<ref name=":2" />
