As was discussed in another thread,
About the rough idea of the greenhouse effect and the temperature of the troposphere I said:
So we test the hypothesis and see no troposphere warming in the measured radiosonde data and a distinct lower warming trend in the calculated satellite data:

How about the stratosphere data, that would require a cooling trend.

Yes, they are cooler now than usual albeit without a distinct trend. We see some distinct spikes and a distinct lasting drop between 1993 and 1994, the temperature seems to be slowly recovering again. Not nearly a steady trend inverted proportional to the increase in greenhouse gasses.
So what would be causing this behaviour of the stratosphere?
However I stand by what I've said, I can't see any mechanism that accounts for the tropo. warming and upper strato cooling. ...with the panoply of technology we have, there seems no alternative to the CO2 warming theory.
About the rough idea of the greenhouse effect and the temperature of the troposphere I said:
Facts & physics: The sunlight that hits the Earth surface is absorbed by the surface, heating it. CO2 is not interfering with this. The surface heating causes reradiating of heat waves (Infra red) and some of this is absorbed by the CO2 molecules in the air, warming the air.
Hypothesis: So with more CO2 in the lower atmosphere air, (troposphere) gets warmer and since this is the first effect this trend should be the strongest. The warmer troposphere is keeping the Earth warmer but this is secondary and hence this should be the weaker trend. Due to this resistance of IR radiation the higher atmosphere, or stratosphere cools.
