Some eruptions cooled the global climate—inducing a volcanic winter—depending on the amount of sulfur dioxide emitted and the magnitude of the eruption. [ 1 ] [ 2 ] Before the present Holocene epoch, the criteria are less strict because of scarce data availability, partly since later eruptions have destroyed the evidence.
Climate changes of 535-536 (535–536 AD), sudden cooling and failure of harvests, perhaps caused by volcanic dust 900–1300 Medieval Warm Period , wet in Europe, arid in North America, may have depopulated the Great Plains of North America, associated with the Medieval renaissances in Europe
This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536); its effect on the climate may have been exacerbated by the 1814 eruption of Mayon in the Philippines. The significant amount of volcanic ash and gases released into the atmosphere blocked sunlight, leading to global cooling.
Along with Zavaritskii, three other volcanoes blew their tops between 1808 and 1835. They marked the waning of the Little Ice Age, a climate anomaly that lasted from the early 1400s to around 1850.
He suggests that changes in the concentration of these gases could bring climate change. [20] 1883 Eruption of Krakatoa in Indonesia. The sound of the explosion is heard as far as Australia and China, the altered air waves causes strange colours on the sky and the volcanic gases reduce global temperatures during the following years.
A.D. 79: Mount Vesuvius, Italy. Mount Vesuvius has erupted eight times in the last 17,000 years, most recently in 1944, but the big one was in A.D. 17. One of the most violent eruptions in history ...
Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...
From ancient times, people suspected that the climate of a region could change over the course of centuries. For example, Theophrastus, a pupil of Ancient Greek philosopher Aristotle in the 4th century BC, told how the draining of marshes had made a particular locality more susceptible to freezing, and speculated that lands became warmer when the clearing of forests exposed them to sunlight.
