Ned Nikolov,a physical scientist and researcher affiliated with Colorado State University and Karl Zeller a retired U.S. Forest Service meteorologist published a study that found that recent warming is not the result of increasing CO2."The greenhouse theory claims that atmospheric composition is important.They argue that increases of the carbon dioxide in the atmosphere cause global warming and that we must stop burning fossil fuels.That is completely wrong".After analyzing satellite data,the 2 researchers found that the earth has warmed & absorbs more sunlight because of reduced cloud cover.
