Dimming appears to be caused by air pollution. Burning coal, oil and wood, whether in cars, power stations or cooking fires, produces not only invisible carbon dioxide (the principal greenhouse gas responsible for global warming) but also tiny airborne particles of soot, ash, sulphur compounds and other pollutants.

What is global dimming caused by?

It's due to something happening on Earth that blocks the sun's rays. Global dimming is important from a climate standpoint because less sunlight reaching the Earth creates a cooling effect. What causes global dimming? Most likely air pollution, in the form of tiny particles produced when we burn fossil fuels.

What pollution is the major cause of global change?

Global warming, also known as climate change, is caused by a blanket of pollution that traps heat around the earth. This pollution comes from cars, factories, homes, and power plants that burn fossil fuels such as oil, coal, natural gas, and gasoline. Global warming pollution knows no boundaries.
