Shrinking Sky - Cloud Tops Dropping Closer To Earth

The sky is falling… sort of. Over the last 10 years, the height of clouds has been shrinking, according to new research.

The time frame is short, but if future observations show that clouds are truly getting lower, it could have an important effect on global climate change. Clouds that are lower in the atmosphere would allow Earth to cool more efficiently, potentially offsetting some of the warming caused by greenhouse gases.

"We don't know exactly what causes the cloud heights to lower," study researcher Roger Davies of the University of Auckland in New Zealand said in a statement. "But it must be due to a change in the circulation patterns that give rise to cloud formation at high altitude."

Is it possible that when gases are cooled they become less energetic and contract in volume? ie. the Earth is cooling - thanks to the Sun.
