Some large events can throw up dust (Sulfur dioxide) that blocks out sun light, cooling the earth under its shadow. Some events can block the sun for days and few can throw up such fine dust in such great numbers that cooling can last for years. Such events are very rare, one every 500 years. When volcanoes throw massive amount of fine dust that can cool the surface, they can also throw out massive amounts of carbon dioxide. The dust last for days until it settles, but the carbon dioxide can last for decades. So the effect is cooling followed by warming.

Are volcanic eruptions weather or climate related?
No, climate and weather do not cause volcanic eruptions. However weather affects the products produced by a volcanic eruption.
What kinds of climate change might be caused by volcanic eruptions?
hindi ko alam
Why do volcanoes errupt due to global warming?
Volcanic eruptions are not caused by anything related to climate.
Dust and ash entering the atmosphere as a result of volcanic eruptions can affect earths?
Weather and climate.
Why does it matter that volcanoes erupt?
One major reason is that erupting volcanoes are very dangerous. Volcanic eruptions can very very deadly and destructive. The largest eruptions can even affect the climate world wide. Additionally, many islands in the world are made up of material expelled by thousands of volcanic eruptions.
How has the Earth's climate changed over time?
Earth's climate has changed due to ice ages, volcanic eruptions, asteroid impacts, the Sun's cycle, and global warming.

Weather and climate.
What are some natural events that have caused change in earth climate?
The eruptions of volcanos can cause significant climate changes due to volcanic ash in the air.
What causes masive climate changes?
global warming, massive (vei8) volcanic eruptions & meterorite hits (ask the dinosaurs)
True or false major volcanic eruptions and the aerosols they release contribute to short term warming of earth climate?
false
