The amounts of material that will be put into the upper atmosphere by such a project are utterly negligible compared to what's already there; it doesn't matter which particular material you are thinking of. The only reason there is any noticeable effect at all is because the material ejected from the shuttle is concentrated in one small area. It doesn't stay that way. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
