The Terra satellite determines the height of cloud tops by taking stereographic images of clouds. It is an automated process. It cannot tell the difference between cirrus aviaticus or natural cirrus (since they are the same thing, differing only in the manner in which their formation is triggered).
The Department of Transportation and PARTNER disagree with you.
crap like the clouds are sinking wee are doomed/saved or whatever else stupid science which is a fancy word for guesswork
Anyone who believes groupthink is not a problem in the insular self-righteous climate science community, should read the Hockey Stick Illusion or wade through just a few of the infamous emails hacked from the Climate Research Unit at the University of East Anglia.)www.counterpunch.org...
To compensate for a doubling of CO2, which causes a greenhouse warming of
4 W/m2, the required continuous stratospheric sulfate loading would be a sizeable
5.3 Tg S, producing an optical depth of about 0.04. The Rayleigh scattering optical
depth at 0.5 ?m is about 0.13, so that some whitening on the sky, but also colorful
sunsets and sunrises would occur. It should be noted, however, that considerable
whitening of the sky is already occurring as a result of current air pollution in the
continental boundary layer.
Locally, the stratospheric albedo modification scheme, even when conducted at
remote tropical island sites or from ships, would be a messy operation. An alternative may be to
release a S-containing gas at the earth’s surface, or better from balloons, in the tropical stratosphere. A gas one might think of is COS, which may be the main source of the stratospheric sulfate layer during low activity volcanic periods (Crutzen, 1976), although this is debated (Chin and Davis, 1993).
However, about 75% of the COS emitted will be taken up by plants, with unknown
long-term ecological consequences, 22% is removed by reaction with OH, mostly
in the troposphere, and only 5% reaches the stratosphere to produce SO2 and sulfate particles (Chin and Davis, 1993). Consequently, releasing COS at the ground is not recommended.
However, it may be possible to manufacture a special gas that is
only processed photochemically in the stratosphere to yield sulfate. The compound
should be non-toxic, insoluble in water, non-reactive with OH, it should have a
relatively short lifetime of less than about 10 years, and should not significantly
contribute to greenhouse warming, which for instance disqualifies SF6.

If your statement is true, then it would seem obvious why they reached the conclusion they did.
The cloud tops are lower because they were not actually measuring just cloud tops. Some of the cloud tops they were measuring were from airplanes and that means the whole study is invalid.
You can't have a valid study about clouds if your data is actually mixed with data about jet exhaust.
The only windows of control that there have been were 9/11 and the Iceland volcano which both showed that without jet emissions (whatever they may in the end turn out to be) everything was a lot nicer.

A "lot nicer"? Care to quantify that?
Airliners contribute a tiny fraction, over-all, to the total pollution from internal combustion fossil-fueled engines. Compared to the hundreds of millions of cars, trucks, motorcycles, scooters, diesel railroad locomotives, gas-powered lawnmowers and leaf blowers, diesel electrical generators, etc, etc, etc.....
No - you don't get any links because you've been given the links and you don't read them preferring your own pseudo-self-serving-'science' full with mis-information and dis-information to anything real.

Everyone knows what I'm talking about when I say 'a lot nicer.' No X's, grids, rainbows in wierd places, white lines, super-reflectant haze, artificial clouds and chemical spew.
