When a powerful volcano erupts, it sends dark clouds of ash into the atmosphere. These dark clouds block out the sun's rays, causing global dimming.

What causes global dimming?
Global dimming stops the sun's heat and light reaching the earth. If this lasts for a long time it could cause much loss of life. Global dimming is one suggestion for the death of the dinosaurs.
How do you reduce global dimming?
Global warming is the observed increase in temperature caused by the increase of greenhouse gasses. Greenhouse gasses warm the planet by trapping infrared radiation and slowing its escape into space. Global dimming could roughly be described as the opposite. It is caused by fine particles in the atmosphere (known as "aerosols"). These particles reflect sunlight away, reducing the overall amount of radiation that enters the planet. This has a cooling effect.
How may the increase of air pollution in the Earth's atmosphere cause global warming?
Air pollution would not cause global warming. Pollution of our air is rarely done with colorless gases. Sulfur Dioxide, for example has some color. These gases would cause an effect called global dimming. This increases the albedo effect and would cool the planet. Water vapor and CO2 cause the warming our planet. Most of this is very natural (over 99%). The addition of CO2 to our atmosphere is believed to cause some level of warming.
What was the primary cause of global interdependence?
The Major Cause of the Global Crisis
Can global warming cause lake fires?
No global warming can not cause Lake fires .

What can be done to stop global dimming?
To battle Global Dimming we could try to reduce aeroplane contrails and to be done on a Global scale we would see a large increase in Global Warming.
What effects do volcanoes have on global warming and ozone layer depletionhtml?
Volcanoes do cause global warming and ozone depletion. But the amount is very low.
What is the meaning for global dimming?
Global dimming is a gradual reduction of global direct irradiance, or electromagnetic radiation, that hits the Earth's surface. The process interferes with the hydrological cycle.
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.
Why is global dimming dangerous?
Global dimming occurs when the clouds in the sky reflect the sun's energy back into space. It is also caused by greenhouse gasses. Global dimming can be dangerous because it indirectly causes crops to die, and the waters in the world's oceans to become cooler.
Can global warming cause volcanoes to erupt?
No, quite the opposite really. Volcanoes add to the atmospheric greenhouse gasses.
What can global dimming do for us?
Global dimming was a time in the last century when temperatures were cooler because there was so much pollution in the air that it reflected away some of the sunlight. This was not a good situation. If global dimming returned the earth might be cooler, but the air would be more polluted causing lung diseases and other undesirable effects.
What factors other than smog contribute to global dimming?
Aerosols
Why should people care about global dimming?
because it's effect a lot of everything

How do you prevent global dimming?
Keep the air clean with Clean Air Acts around the world.
