"Stratosphere cooling" refers to the cooling or decrease in temperature of the stratosphere, which is a layer of Earth's atmosphere above the troposphere. It happens when the stratosphere becomes colder than usual.

Eli, Gavin is arguing above that adding greenhouse gasses would cause the stratosphere to cool even if the stratosphere was not being warmed by the adsorption of UV and that this is the explanantion
of stratosphere cooling.
An experiment starting next month in the U.K. will pump water one kilometer into the air to test a new climate - cooling method that eventually could deliver sunlight - reflective sulfate particles into the stratosphere
, the basic issue is that stratospheric temperatures change in response to local effects, they do not change because the troposphere does (i.e. troposphere warming does NOT
imply stratosphere cooling).
What's the probability of
the stratosphere cooling while the earth gets warmer?
When ozone is lost from the stratosphere, it is not available to absorb incoming ultraviolet light from the Sun; so
the stratosphere cools.
The hot dry subtropical climate belts have expanded as the troposphere has warmed and
the stratosphere cooled [33]--[36], contributing to increases in the area and intensity of drought [37] and wildfires [38].
There are empirical evidence for the exact opposite — a cooling stratosphere (Why does
the stratosphere cool when the troposphere warms?).
Another factor is the fact that stratospheric temperatures are generally cooling as greenhouse gases increase (see MSU Temperature Record, also Why does
the stratosphere cool when the troposphere warms?).
However, there are also increases in the upper troposphere / lower stratospheric gradients (due to
the stratosphere cooling and the troposphere warming) and that has been shown to lead to increases in wind speeds at the surface.
On the issue of why
the stratosphere cools here is a nice illustration of the relative roles of ozone depletion and greenhouse gases, plus links to a strange discussion of same.
Question: Why is
the stratosphere cooling while the troposhere warms, and why are nights warming faster than days?
2)
The stratosphere cools.
He then says he doesn't know why
the stratosphere cooled as the troposphere warmed.
The stratosphere cools when ozone is destroyed because there is less ozone to absorb UV radiation.
For these two reasons, the current climate models predict that increasing infrared - active gases should actually speed up the rate at which the tropopause and
stratosphere cool.
The hot dry subtropical climate belts have expanded as the troposphere has warmed and
the stratosphere cooled [33]--[36], contributing to increases in the area and intensity of drought [37] and wildfires [38].
To say nothing of the warming trends also noticed in, for example: * ocean heat content * wasting glaciers * Greenland and West Antarctic ice sheet mass loss * sea level rise due to all of the above * sea surface temperatures * borehole temperatures * troposphere warming (with
stratosphere cooling) * Arctic sea ice reductions in volume and extent * permafrost thawing * ecosystem shifts involving plants, animals and insects
