How did the eruption of Mt Pinatubo affect the global temperature?

Sulfur dioxide released by the eruption formed tiny droplets of sulfuric acid in the upper atmosphere, which blocked out a small portion of the sun's light, slightly lowering global temperatures.

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 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.
How did Mount Pinatubo's eruption affect the rest of the world?
The eruption of Mount Pinatubo in 1991 was one of the largest volcanic eruptions of the 20th century. The eruption ejected massive amounts of ash and sulfur dioxide into the atmosphere, which spread around the globe and had a profound impact on the Earth’s climate. Sulfur dioxide gas reacts with water vapor in the atmosphere to form tiny sulfuric acid droplets. These droplets reflect sunlight back into space, cooling the Earth’s surface. The eruption of Mount Pinatubo injected about 20 million tons of sulfur dioxide into the atmosphere, causing a temporary decrease in global temperatures of 0.5°C (0.9°F). The eruption also had a major impact on the local population. More than 800 people were killed, and tens of thousands were left homeless. The eruption destroyed more than 200 villages and caused billions of dollars in damage.
Can a volcanic eruption drop the global temperature?
Yes, volcanic eruptions can drop global temperature. The release of sulfur dioxide into the stratospheric aerosol layer causes chemical reactions that reflect the sun's rays away from Earth. It has even been studied as a possible (if not controversial) model for counteracting the effects of global warming from carbon dioxide buildup.
How would mount st helens affect the atmosphere?
All depends on the size of the eruption. If it were a big eruption then it could bellow ash and smoke into the atmosphere and cause sunlight and heat to be blocked around the world making the earths temperature fall for a little while. Also it will send gasses like methane, carbon dioxide and sulpher into the atmosphere, adding to the greenhouse gas level and maybe contributing to global warming.

How can a particularly violent volcanic eruption impact global temperature?
Ash released from a volcanic eruption can enter the upper atmosphere where it can reflect sunlight. Volcanoes formed the early atmosphere of the planet, so they definitely can have global impact, an increase in agriculture does not signify a significant change in global temperature.

What abiotic factors affect penguins?
Global warming and the temperature of the ice.
Does global warming affect intertidal zone?
global warming would indeed affect the intertidal zone, it would affect the water levels, salinity and most likely temperature.
What are the secondary effects of the mt Pinatubo eruption?
One would be that due to over 20 million tonnes of Sulphur Dioxide being injected into the atomosphere global temperatures temporarily fell between 1991 and 1993 by half a degree celsius.

How does global warming affect global precipitation?
It would seem logical to assume that increases in temperature would cause increases in precipitation.
Could human activities affect earth's capacity to limit changes in global temperature?
Yes. Deforestation, which is primarily a human activity, affects the earth's capacity to control global temperature.
How does the ozone affect the weather?
Ozone causes global warming. It then increases the temperature changing the weather.
