Volcanoes can cause a slight warming effect because of their carbon dioxide emissions, and a somewhat greater, but short-term, cooling effect due to particulate emissions. Apart from the short-term cooling effect, volcanoes are not considered to have a significant effect on temperatures, compared to the effect from human activities.

∙ 10y agoThe amount of volcanic activity that we have now does not increase global temperatures. A volcanic eruption does emit some carbon dioxide, but man, in a year, by burning fossil fuels, emits more than 150 times the average yearly emission from volcanoes.
Volcanic eruptions actually cause a cooling of the earth, though only briefly. Dust and ash in the atmosphere acts as a barrier to the sun's heat, and temperatures cool till the ash settles.

How does dust from volcanoes link to global warming?
Volcanic eruptions can reduce global warming for a short time by blocking and reflecting the sun's heat with their dust and ash.
Which is best used to track the global movement of volcanic ash after an eruption?
satellite photographs
How does volcanic ash affect people?
kill and harms them in many way
What are two factors that can affect the distance that volcanic ash can travel?
The blast of the volcano, the wind, and how light the ash is all affect how far it will travel.
How does volcanic ash affect humans?
volcanic ash can clog up the lungs when inhaled suffocating the human, it can get in their eyes and irratate and blind them, it can burn them then infect the injury or it can block out the light and heat of the sun

What is volcanic ash and how does it affect worldwide climate patterns?
Volcanic Ash is the material produced from volcanic eruptions which is ejected into the atmosphere. It is normally comprised of carbon and mineral based debris, rock strata, granite, basault dust etc. This material sits in the atmosphere and actually absorbs thermal energy and also helps to shield the earth from sunlight, as a result it lowers global temperatures slightly when there is a large eruption akin to either Krakatoa or St helens. It is thought volvanic eruptions could actually slow down global warming.
How does global warming cause volcanoes?
Global warming has no effect on volcanoes. It's the other way round. Volcanoes can increase global warming slightly if the emit carbon dioxide. And they can reduce global warming for a while if their dust and ash block out and reflect the sun's rays.
Does global warming have an effect on volcanos?
No, Global warming has no effect on volcanoes. It's the other way round. Volcanoes can increase global warming slightly if the emit carbon dioxide. And they can reduce global warming for a while if their dust and ash block out and reflect the sun's rays.
Does global warming take part in volcanoes?
No, global warming takes no part in volcanoes. It's the other way round. Volcanoes can increase global warming slightly if the emit carbon dioxide. And they can reduce global warming for a while if their dust and ash block out and reflect the sun's rays.

Do volcanoes prevent global warming?
Dust and ash from volcanic eruptions can darken the sky for weeks at a time. This prevents sunlight warming the earth. However, this is usually only temporary and will not prevent global warming.
Is it true that volcanic ash can affect the climate?
Yes it is very true

The blast of the volcano, the wind, and how light the ash is all affect how far it will travel.
Do volcanic eruptions increase global warming?
Usually not. The amount of carbon dioxide emitted by volcanoes is very small compared to our emissions from the burning of fossil fuels. In fact, the dust and ash emitted by volcanic eruptions often shields the earth from the sun's rays for days and sometimes weeks, bringing a cooling effect.
