February 22, 2012 – EARTH - Earth’s clouds got a little lower — about one percent on average — during the first decade of this century, finds a new NASA-funded university study based on NASA satellite data. The results have potential implications for future global climate. Data from NASA’s MISR instrument on NASA’s Terra spacecraft 
show that global average cloud height declined by about 1 percent over the decade from 2000 to 2010, or around 100 to 130 feet (30 to 40 meters). Lead researcher Roger Davies said that while the record is too short to be definitive, it provides a hint that something quite important might be going on. Longer-term monitoring will be required to determine the significance of the observation for global temperatures. 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.” NASA’s Terra spacecraft is scheduled to continue gathering data through the remainder of this decade. Scientists will continue to monitor the MISR data closely to see if this trend continues. –Physics
The timing of the decline in the planet’s cloud height also curiously corresponds to a mysterious period of acceleration of the migration of the magnetic north pole towards Siberia as the chart shows on the left. Might the two events be related? -The Extinction Protocol
