Why did the mt. Pinatubo eruption result in global temperatures dropping two degrees?
The eruption of Pinatubo blew thousands of tons of fine ash into the upper stratosphere. The ash clouds were carried all around the world, and increased the Earth's albedo, or reflectivity, enough so that enough sunlight was reflected back into space that the Earth actually began to cool down.
These eruptions have happened many times before; for example, the 1815 eruption of Mount Tambora in Indonesia caused the 1816 "Year Without A Summer", a time of widespread crop failures and famine.

Why did the mount Pinatubo eruption result in global temperatures dropping almost two degrees?
The 1991 eruption of Mount Pinatubo released massive quantities of sulfur dioxide. This led to the formation of tiny droplets of sulfuric acid in the stratosphere. These reflected sunlight back into space, reducing global temperatures.
Why did the Mountain Pinatubo eruption result in global temperatures dropping almost two degrees?
The eruption of Mount Pinatubo in June 1991 released vast amounts of sulfur dioxide into the stratosphere, forming a sulfate aerosol cloud that reflected sunlight away from the Earth. This resulted in a temporary cooling effect on the planet's surface, as the aerosols blocked solar radiation. The cooling, which lasted for about 1-2 years, contributed to a notable drop in global temperatures, with estimates of around 0.5 to 1 degree Celsius in the year following the eruption. The overall impact was significant enough to cause a nearly two-degree drop in some regions, particularly in the Northern Hemisphere.
How hot was the lava in mount Pinatubo?
Mt Pinatubo is a composite volcano and the lava is primarily dacitic making it explosive and highly viscous. Dacite would likely erupt at about 800 degrees Celsius.
How did Mount Pinatubo eruption affect global temperature?
The eruption of Mount Pinatubo in June 1991 injected vast amounts of volcanic ash and sulfur dioxide into the stratosphere, which formed sulfate aerosols. These aerosols reflected sunlight away from the Earth's surface, leading to a temporary cooling effect. Subsequent studies indicated that global temperatures dropped by about 0.5 degrees Celsius for approximately two years following the eruption. This phenomenon highlighted the significant impact that large volcanic eruptions can have on the climate.
What can happen to global temperatures for several years after a volcanic eruption?
After a volcanic eruption, particularly a large one that emits significant amounts of ash and sulfur dioxide into the atmosphere, global temperatures can temporarily decrease. This occurs because the ash and sulfur particles reflect sunlight away from the Earth, leading to a cooling effect that can last for several years. The extent and duration of this cooling depend on the eruption's magnitude and the amount of aerosols released. Notable examples include the 1991 eruption of Mount Pinatubo, which caused global temperatures to drop by about 0.5 degrees Celsius for a couple of years.

What thing's temperature may reach as high as 2000 degrees Celsius?
Lava during a volcanic eruption can reach temperatures of 2000 degrees Celsius.
What might happen if a major volcanic eruption every year?
Global temperatures might cool by several degrees
What digrees do volcaneos get up to when they irrupet?
During volcanic eruptions, temperatures can vary significantly depending on the type of eruption and the materials involved. Lava temperatures typically range from about 700 to 1,200 degrees Celsius (1,300 to 2,200 degrees Fahrenheit). In explosive eruptions, pyroclastic flows can reach temperatures of up to 1,000 degrees Celsius (1,832 degrees Fahrenheit). Additionally, volcanic gases can also be extremely hot, contributing to the overall heat during an eruption.
What might happen if a major volcanic eruption occurred every year?
Global temperatures might cool by several degrees
How hot is mount vesuvius?
Currently the temperature on Mount Vesuvius is no different from that of an ordinary mountain. Temperatures at certain spots may approach 2,000 degrees Fahrenheit during an eruption, but the last eruption at Mount Vesuvius was in 1944.
How hot is the plume?
The temperature of a volcanic plume can vary significantly depending on the type of eruption and the materials involved. Typically, temperatures can range from about 100 to 1,000 degrees Celsius (212 to 1,832 degrees Fahrenheit). In explosive eruptions, plumes can reach even higher temperatures, potentially exceeding 1,200 degrees Celsius (2,192 degrees Fahrenheit). The heat is primarily generated by the magma, gases, and volcanic ash released during an eruption.
Coldest planet in world?
The coldest planet in our solar system is Neptune, with average temperatures around -214 degrees Celsius (-353 degrees Fahrenheit). However, some regions of Uranus experience even lower temperatures, dropping to about -224 degrees Celsius (-371 degrees Fahrenheit). These extreme temperatures are due to their distance from the Sun and the composition of their atmospheres, which contain hydrogen, helium, and methane.
