And there is. Voila.

Nice theory, unfortunately the tropospheric data does not support what your attribution of the cause.

Nor does the theory take into account other reasons for global climate changes that overwhelm any manmade influences by more than an order of magnitude.

100 kyr Glacial Cycle:

On those cycles we are due for the onset of another glaciation totally unrelated to any of the "global warming or global cooling" theories of the environmental opportunists.

As much as you don't think I know nothing about the fundamentals, I know about them and they are easy to find on the Web. Such as:

Causes of Climate Change

As for the tropospheric data, the satellite data doesn't tell the whole story:

Global, hemispheric, and zonal temperature deviations derived from radiosonde records

Harvard Medical School, Center for Health and the Global Enviroment: Quarterly Review, Global Climate Change Vol. 2, No. 1, March 2000


"Angell JK, Comparison of surface and tropospheric temperature trends estimated from a 63-station radiosonde network, 1958-1998. Journal of Climate 1999;12:2551-2561.

While debate continues to rage over the future impact of climate warming, researchers are continuing to probe what has been happening recently. Much has been made of the surface temperature trends showing rapid warming during the last few decades. However, suspicions linger that some of this warming could be due to increases in the urban heat island effect, which may influence the temperature records at low levels. Therefore, it is important to determine what has been happening at higher elevations, where greater atmospheric mixing diminishes such concerns.

In this article, trends for the last 40 years in radiosonde (instrumentation used to gather and transmit meteorological data) temperatures extending up to 30,000 feet elevation were compared with surface temperature records in similar locations. The surface warmed at 0.14 degrees Centigrade per decade; the atmosphere from 5,000 to 30,000 feet warmed at only a slightly lower rate (0.10 degrees Centigrade per decade). There are hemispheric differences, but it appears that the troposphere as a whole seems to be warming, at least in these locations.

However, radiosonde data used in this analysis is available primarily for land stations in the Northern Hemisphere. Unfortunately, there is no other source for data above the surface extending back as far as 1958. Satellite data, which has the advantage of being global, is more ambiguous about warming at levels above the surface, but this data extends back only 20 years, and its trends may be affected by calibration and orbital changes. Obtaining global records for the atmosphere above the surface, and maintaining the consistency of the recording instruments, will probably continue to be a problem."
