GLOBAL DIMMING- SHOULD WE BE CONCERNED

GLOBAL DIMMING SHOULD WE BE CONCERNED? The concept of global dimming comes as a counter act to that of global warming. Both are ironically due to pollutants in the atmosphere. Just as much as the earth would be below the freezing point of water without global warming, so it is that without global dimming the earth would be scotching hot. Global dimming is caused by what we know as aerosols. Aerosols are a mixture of dust water or soot that cause turbidity in the atmosphere. These aerosols then cause a cooling of the atmosphere by acting as catalysts in the formation of clouds. Clouds formed by aerosols are more reflective of both heat and light sending the rays back into space. I think that without global dimming the earth would already be in a state whereby it is impossible to live in due to the fact that global warming is a reality and on the increase. In fact the magnitude of global warming is not entirely felt because aerosols mask the whole effect. It is for the above stipulated reason then that I feel we should be concerned, if not I think we will be deceived into thinking the effects of global warming are minor whereas its just global dimming masking it.
