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.

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.

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.

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.

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.
