Cloud feedback is the coupling between cloudiness and surface air temperature where a surface air temperature change leads to a change in clouds , which could then amplify or diminish the initial temperature perturbation .. temperature. temperature. feedback. climate change feedback. Cloud feedbacks can affect the magnitude of internally generated climate variability or they can affect the magnitude of climate change resulting from external radiative forcings .. Global warming is expected to change the distribution and type of clouds .. Global warming. Global warming. Seen from below , clouds emit infrared radiation back to the surface , and so exert a warming effect ; seen from above , clouds reflect sunlight and emit infrared radiation to space , and so exert a cooling effect .. infrared radiation. infrared radiation. Cloud representations vary among global climate models , and small changes in cloud cover have a large impact on the climate .. cloud. cloud. climate models. climate models. Differences in planetary boundary layer cloud modeling schemes can lead to large differences in derived values of climate sensitivity .. cloud. cloud. planetary boundary layer. planetary boundary layer. climate sensitivity. climate sensitivity. A model that decreases boundary layer clouds in response to global warming has a climate sensitivity twice that of a model that does not include this feedback .. climate sensitivity. climate sensitivity. feedback. climate change feedback. However , satellite data show that cloud optical thickness actually increases with increasing temperature .. cloud. cloud. temperature. temperature. optical thickness. optical thickness. Whether the net effect is warming or cooling depends on details such as the type and altitude of the cloud ; details that are difficult to represent in climate models .. cloud. cloud. climate models. climate models
