Name one doomsday prediction by the "experts" that has ever happenned. Temperature records keeping began in 1880. The warmest period on record was in the 1930's, that is until NOAA "adjusted" the data. Anyone remember the "Dust Bowl"? Can anyone explain the Medieval warming period in terms of man made effects? You know aroud year 1000 AD when the Vikings in open boats rowed to discover "Greenland". There is only one think that is constant about the climate and that is constant change. CO2 represents less than 1/2 of 1 percent of the atmosphere. The Sun drives the climate, nothing else is significant. See www.climatedepot.com for real facts.
