Earth’s clouds are getting lower, NASA satellite finds

A consistent reduction in cloud height would allow Earth to cool to space more efficiently, reducing the surface temperature of the planet and potentially slowing the effects of global warming. This may represent a “negative feedback” mechanism — a change caused by global warming that works to counteract it. “We don’t know exactly what causes the cloud heights to lower,” says Davies. “But it must be due to a change in the circulation patterns that give rise to cloud formation at high altitude.

Cool that this could work as a negative feedback stabilizing climate. Gaia Theory, anyone?
