Utilising Cloud Cover Elevation Alteration to Control Global Warming

[Veli Albert Kallio]

A new negative feedback has been observed which opens a possibility for a temperature adjustment and cooling by cloud cover height alteration.
 
New reasearch suggests the upper atmosphere is getting colder or drier to the extent that the cloud tops now reach 1% lower than 10 years ago.

This is a novel negative forcing from greenhouse gas forcing that traps more heat and moisture to the lower parts of the air column:

I look forward to seeing how this holds up to scrutiny. Given the latitudinal gradient of temperature, the result would seem to suggest that clouds get lower as one goes toward the equator, and are lower during the summer than the winter. Is this really the case?

While changes could be induced by circulation changes (e.g., a strengthened Hadley circulation could perhaps thin the subtropical boundary layer), I look forward to understanding better how global the effect is found to be.

One years worth of data does not a trend make.  Throw out the data around 2008 and you get a straight line. I would like to see the data for myself or at least a paper. However, Solomon et al. paper (attached) shows that changes in SST, may be resulting in less UTLS water vapor.  See also the attached paper by Yeh et al. on the shifting El Nino pattern.  So the reported observations could be plausible.
