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.
The 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.
Volcanic ash after an eruption remains in the air for days, and sometimes weeks. This ash is made up of tiny particulates that reflect and block solar radiation, so the earth cools a little after an eruption.
it makes certain areas more humid and also makes globle warming more difficult to resolve
Volcanic eruptions can reduce global warming for a short time by blocking and reflecting the sun's heat with their dust and ash.

The blast of the volcano, the wind, and how light the ash is all affect how far it will travel.
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

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.
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.
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.
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.

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.
Yes it is very true

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.
