Hansen' s doctoral thesis of 1967, was that the higher than expected   
   temperature at the surface of Venus, is caused by dust particles which block   
   or trap microwaves.   
      
   In this thesis, he states directly that neither water vapor or co2 are   
   important to the complete thermodynamic analysis he has supposedly achieved.   
      
   His thesis was not rejected by the theoretical science of the time, because   
   this concept of specific reactivity of some gases to infrared, from   
   pre-science, was rejected because of no supportive empirical science.   
      
   Those educated in higher education of any physical science at this time, never   
   heard of greenhouse gases, within or without their field of specialty.   
      
   Methane exist at about 1 ppm,   
   Or about 1,500 parts per BILLION.   
      
   Methane oxidizes naturally in the atmosphere in 10-12yrs,   
   Therefore it does not accumulate.   
      
   If changes in methane of parts per 10 million or 100 million can affect   
   atmospheric temperatures, this surely could be demonstrated in the   
   laboratory,  WHICH IT CANNOT.
