Polar ice caps are melting. Glaciers are disappearing. Average temperatures across the globe are increasing. The Intergovernmental Panel on Climate Change lays the blame for global warming squarely at the feet of human activity, generating what is now known as greenhouse gases, the most important gas identified as carbon dioxide. Author Dr. Sam O. Otukol believes there are other scenarios. In Climate Change: Is It Really Caused by Carbon Dioxide? he focuses on global changes in climate and explores a wide range of causes. Otukol discusses the key elements of the atmosphere and delves into the creation of carbohydrates and what happens when those carbohydrates or hydrocarbons are burned or metabolized. Climate Change: Is It Really Caused by Carbon Dioxide? assigns less significance to carbon dioxide as an alleged key element in creating the greenhouse effect and identifies another gas as the potential villain. Supplemented with applicable graphics and tables, Otukol offers an alternative theory on global warming and presents global warming mitigation strategies.
