The Way Volcanoes Shape the Global Climate Conditions
After the 100-day eruption of the Krakatau volcano in 1883, the relationship between major eruptions and adverse weather changes was established. A powerful emission of ash and gases into the upper atmosphere caused a global decrease in air temperature, which lasted in some places for more than one year. It is believed that as a result of a powerful eruption, ash and gas fell into the stratosphere and were there for several years. For the most powerful eruptions in modern history, such consequences turned out to be so noticeable that they gave some skeptics a reason to declare a person’s influence on climate insignificant, or even non-existent.
Volcanoes Directly Affect Climate
In fact, volcanoes have the ability to directly influence the climate. But it would be wrong to blame them only for global warming since volcanoes can both increase and decrease air temperature indicators.
The degree of influence of a volcanic eruption on the climate depends on the power of the eruption, and not only on the mass of emitted gases and small particles, which scientists call aerosols but also on the height to which they are thrown. If the volcano “shot” high enough, then in the stratosphere, at an altitude of more than 15-20 kilometers, the products of the eruption may be active for several years.
Other observations show that volcanoes can noticeably cool the planet – after another famous eruption, the Philippine Pinatubo Volcano in 1991, the average global temperature as early as next year, according to scientists, “lost” 0.5 degrees Celsius.
As part of these findings, scientists also suggest that the volcano could be the cause of the death of ancient Egypt. Scientists believe that the eruption contributed to global climate change and, as a result, the extinction of the Nile.
Scientists have yet to study all the mechanisms of the behavior of volcanoes and the possibility of their influence on the atmosphere. And we suggest you always stay up to date with reliable weather information and use Free Weather API for your website.
