Mount Tambora Volcano
Volcanoes are like pimples on the face of the Earth. Except, instead of spewing gross pus when they erupt, Volcanos drown the surrounding area in ash and hot lava, and coat the entire sky in acidic rain and dark clouds. Come to think of it, volcanos are nothing like pimples on the face of the Earth
In 1815, Tambora, an Indonesian volcano, erupted with such magnitude that it may have resulted in worldwide climate change. The volume of magma that spewed from the volcano is estimated to be around 24 cubic miles which, by our paper-and-pencil estimates, would require a sacrifice of two million virgins. Terrifyingly enough, the magma wasn't the most destructive part of the eruption. Several million tons of sulphur dioxide were emitted into the Earth's atmosphere. The gas quickly turned into a large cloud which encircled the Earth and scattered sulphuric acid droplets in the form of acid rain. It's scary to think that the precipitation that was sizzling skin in South America could be caused by a volcanic eruption on the other side of the world.
Ironically, this eruption of hot magma led to a massive cooling of the entire Earth's surface. 1816 became known in Europe and America as the “year without a summer." Snow was recorded falling in New England in June, and the New World's ample guild of sunglass vendors all went bankrupt (we presume). This, the largest volcano eruption in history, is estimated to have killed 71,000 people. Not only that, but only about 10k died as a direct result of the eruption, the remainder perished at the hands of the resulting climate change (North America had their worst famine of the 1800s as a result). So, while the phrase "polar vortex" may sound scary, it's still nothing compared to "volcanically-caused climate change."
