Satellite Data Show Clouds Have Cooling Impact
Clouds have a cooling effect on global temperatures, science writer Willis Eschenbach reports after examining data from NASA's CERES satellite. A negative temperature feedback for clouds would undermine alarmist computer models programmed to assume additional cloud formation caused by modest global warming will produce a positive feedback leading to still warmer temperatures.
Eschenbach, writing for meteorologist Anthony Watts' Watts Up With That? website, documents surprising global variance regarding the impact of cloud cover on temperatures. In some regions, cloud cover has a warming effect on temperatures. In other regions, cloud cover has a cooling effect on temperatures. Overall, cloud cover produces a negative temperature feedback, which is exactly the opposite of what alarmist computer models are programmed to assume.
