Do Atmosphere Temperatures Support Greenhouse Gas Warming Theory?

A paper published this month in Journal of Atmospheric and Solar-Terrestrial Physics evaluated the atmospheric temperature trends of the UAH satellite temperature record to determine if the data supports the theory that global warming is mainly due to the increase in greenhouse gases, hereafter GHG theory.  The paper evaluated temperature trends in four vertical regions and five latitudinal bands. The GHG theory (as used in climate models) requires that the temperature change is more enhanced at high altitudes than near the surface, that near-surface temperature trends are amplified at high latitudes in each hemisphere, that the stratosphere temperature decline in response to tropospheric warming and that the tropopause increases in height. The paper reports;

·        The troposphere temperature trends decreases with height.

·        The lower troposphere temperature trends in the southern hemisphere decreases at high latitude.

·        The thermal regime in the lower stratosphere is mainly affected by the ozone dynamics and not by the thermal regime in the troposphere alone. Therefore, the observed cooling in the lower stratosphere cannot be attributed unambiguously to the warming of the troposphere.

·        The near zero trend of the tropopause cannot support the increase in the height of tropopause.

Each of the four points is contrary to GHG theory. The atmospheric temperature data does not support the GHG theory, but contradicts it. 

The paper also investigated the temperature variability of the troposphere and the lower stratosphere and to determine whether these are associated. It shows the lower stratospheric temperature anomalies over tropics obey power-law behaviour, while it is not the case for the low stratospheric temperature anomalies over both poles. This may be attributed to the ozone dynamics in this region. The intrinsic properties of the thermal regime in the lower stratosphere are not associated with the thermal regime in the troposphere.
