Climate Change Science is Based on an 1896 Paper

Our understanding that increasing carbon dioxide levels in the atmosphere could change the climate is not new. The relationship between carbon dioxide, water vapor, and climate was first laid out in detail in 1896 by the Swedish physicist Svante Arrhenius, who estimated that a doubling of carbon dioxide levels would cause global warming of 4.9° to 6.1°C. In his landmark paper, Arrhenius reported that "a simple calculation shows that the temperature in the arctic regions would rise about 8°...
