Document Summary
Water vapor is the only substance found in a gaseous, liquid, and solid state on earth"s surface. An extremely important gas in our atmosphere. Over 100 years the earth average surface temperatires has warmed by 0. 8 degrees celsius or 1. 4 degrees f. Current climate models indicate a possible additional rise of 3. 0 degrees c (5. 4 degrees f) by the end of the century. 2016 will be the warmest year for the world on record. 97% of 03 is found in upper atmosphere. 03 in upper atmosphere blocks harmful ultraviolet radiation (uv) Very small concentration by volume (0. 00000002%) or 0. 0002 ppm. Uv rays break down cfcs that release chlorine which in turn destroys the ozone. They can have the opposite effect of a greenhouse gas by causing a cooling of the global temperatures. Aerosols are beneficial as a surface for which water vapor can condense onto to form clouds. Nitrogen dioxide reacts with hydrocarbons in sunlight to produce ozone.
