Atmospheric structure T up to 1500 K due to intense solar radiation Chemical composition changes to be richer in lighter gases, gravitational stratification almost no H2O or ozone T relatively constant, increasing to About 200K at the stratopause Average dT/dh = -6 K/km The region of weather! http://www.mardiros.net/atmosphere/atmosphere_structure.html
Common Pollutants Sometimes called TSP Total volume in the US is about 180Mton/yr: about 3.3lb/day.person Note: this is about HALF of what it was 40 years ago even though the population and economy have grown substantially

Temperature Inversion In extreme cases the temperature can actually increase with height. The inversion inhibits convection and as a result, pollutants can concentrate near the ground. http://www.weatherquestions.com/What_is_a_temperature_inversion.htm

Acid rain patterns in the US NOTE: neutral water is pH=7; the lower the number, the stronger the acid.

Typical TRACE Impurities in Coal (does not include sulphur, which is not a trace impurity!) • How much lead, mercury, and uranium is emitted per year in the US by power plants burning this stuff?

Carbon Cycle http://en.wikipedia.org/wiki/Carbon_cycle
Spectrum of Solar radiation at the Earth’s surface H&K fig 6.2 Absorption bands due to gasses like CO2, H2O, CH4 etc. These are the so-called green-house gasses.
Note that total temperature change across several ice ages was only about 12oC or about 22oF. CO2 Concentrations and Temperature Change
