During the last 3 decades. the concentrations of greenhouse gases have increased monotonically. These are expected to produce warming in the troposphere and cooling at higher altitudes. Expetimental observations of various atmospheric parameters were examined. It was noted that not all parameters showed monotonic trends. In some cases, the trends before and after about 1970-75 were opposite or, the trends developed only after 1970-75. The reason for this transition needs to be explored. A possible cause could be a more rapid increase of CFC concentration in recent years. Also, effect of meteorological fators speciailly sea-surface temperature changes before and after 1975. could be a possible cause though this in turn may be relaled to increasing levels of greenhouse gases.
