This talk will address the changing composition of the atmosphere due to man's effluents.  The talk would touch upon carbon-dioxide and methane from fossil fuel activities, halocarbons from air conditioning, ozone, long range transport of dust and pollutants around the world, and atmospheric warming from all of the above.
