Heaven comes down to Earth for the last 10 years, the cloud descended on average by 1%, the researchers showed the University of Auckland (New Zealand) based on measurements of the upper limit, made from March 2000 to February 2010 with the help of the polygonal Spectroradiometer (MISR) American spacecraft Terra.

1% - 30-40 m is usually reduced due to the fact that at very high altitudes less cloud formed.
The lead author of Roger Davis notes that the data cover too short a period to be able to make far-reaching conclusions. At the same time we can not turn a blind eye to the fact that probably there is something important - and it is related to changes in global average temperature.
The fact that the reduction in the height of the cloud cover of the Earth slightly cooling the planet and possibly slow down global warming. Perhaps we have an example negative feedback mechanism, when the growth temperature reduces the cloud and, respectively, contain warming. Apparently, it has something to do with the atmospheric circulation at high altitudes, but scientists are not yet able to propose a model, fully describing these processes.
