The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
The volcanic winter of 536 was the most severe and protracted episode of climatic cooling in the Northern Hemisphere in the last 2,000 years. [1] The volcanic winter was caused by at least three simultaneous eruptions of uncertain origin, with several possible locations proposed in various continents. Modern scholarship has determined that in ...
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.
Similar climatic effects to "nuclear winter" followed historical supervolcano eruptions, which plumed sulfate aerosols high into the stratosphere, with this being known as a volcanic winter. [223] The effects of smoke in the atmosphere (short wave absorption) are sometimes termed an "antigreenhouse" effect, and a strong analog is the hazy ...
Some scientists have suspected a volcanic winter resulting from the eruption was a big enough shift to wipe out most early humans due to genetic evidence suggesting a steep drop in the human ...
Super volcano is the term used to describe volcanoes that have gradually over time built up immense amounts of magma and could wreak havoc if ejected onto the planet's surface. And in the heart of ...
Year 536 (Roman numerals: DXXXVI) was a leap year starting on Tuesday of the Julian calendar.At the time, it was known as the Year after the Consulship of Belisarius.. In 2018, medieval scholar Michael McCormick nominated 536 as "the worst year to be alive" because of the volcanic winter of 536 caused by a volcanic eruption early in the year, causing average temperatures in Europe and China to ...
But somehow Vesuvius isn't the biggest volcanic threat the modern city faces: Within the Naples metropolitan area is Campi Flegrei, a supervolcano whose eruption 40,000 years ago might have wiped ...
