On a global scale clouds affect the climate by cooling the planet, however, as the global warming progresses the clouds cooling capacity will be lost, according to a study by the Texas A&M University published in the Science journal. The study supports current thinking on how atmospheric carbon dioxide affects global temperature.
Clouds can have both, negative and positive influence on climate and this leads to much insecurity about the amount of warming that will occur in the atmosphere due to increased carbon dioxide concentrations.
So far the scientific community only have a general idea about this effect but overall agrees the feedback is quite positive and that when larger amounts of clouds trap infrared radiation warming increases.
Under the Andrew Dessler lead, scientists have calculated the actual extent of this feedback effect by analyzing the flow of radiation through the upper layers of the atmosphere, satellite data which were collected in a period of ten years. Dessler concludes that the feedback effect is indeed positive and a value that matches the range of existing estimates on how much warming will occur if the doubled atmospheric carbon dioxide.
