Fossil fuel use, as well as producing greenhouse gases, creates other by-products. These by-products are also pollutants, such as sulphur dioxide, soot, and ash. These pollutants however, also change the properties of clouds.
Clouds are formed when water droplets are seeded by air-borne particles, such as pollen. Polluted air results in clouds with larger number of droplets than unpolluted clouds. This then makes those clouds more reflective. More of the sun’s heat and energy is therefore reflected back into space.
This reduction of heat reaching the earth is known as Global Dimming.

Records show that over the past 50 years the average amount of sunlight reaching the ground has gone down by almost 3% a decade. "It's an extraordinary thing that for some reason this hasn't penetrated even into the thinking of the people looking at global climate change. It's actually quite a big deal and I think you'll see a lot more people referring to it." There fore it is a bad thing. Yet in some ways it is not so bad because of the global warming issue I also researched on http://blog.360.yahoo.com/blog-dMWGRys6aa_XpBRW8maZPnay52Qj_6U-?cq=1&p=12, The global dimming will keep the earth from overheating here is an article on that http://www.tonyrogers.com/news/global_dimming.htm I hope I helped you and answered all of your questions because this is a complex contradictory subject.

You are right, it is why the global warming phenomenon, is not really artificial but his caused by multitude factors, some are related to this planet geomagnetic activities, and geologic activities that heat the ocean water and release biogases even more... But the increase in water vapor levels is the real cause of warming at sea levels!!

global dimming can cause an ice age and it also can stop crops from growing with out full sun light and a long growing season many people will die from hunger and if a large volcano should erupt there goes life on earth everything will freezes and all life on earth will change if any life survives. no one can tell for sure what type of life from will evolve.
