Atmospheric Geochemistry/Air Quality:

What is the cause of most air pollution?
Does Hawaii have the least polluted air in the nation (since it is surrounded by water and the wind carries the pollution away)?
Why is the Ozone Hole only over the North and South Poles, and not distributed evenly over the earth's atmosphere?
Atmospheric and environmental condition today "aren't that bad". Current and future environmental regulations should be based on cost and not on how much help the environment actually needs. Can you suggest or evidence in support of this arguement?
Are chlorine emissions from volcanoes more of a hazard to the ozone layer than man made chlorine?
how do marine carbonate sediments effect the concentration of carbon dioxide in the atmosphere and where I can find some information on this topic

Greenhouse Gases/Global Climate

How much would clouds affect the current predictions of global warming? the current global warming models that I am aware of do not include clouds. I think that as the Earth would warm, more clouds would develop that would reflect more light, so clouds would ack as a safety valve for heat, am I right, is there any data?
