Professor Kerry Emanuel claims that human impact is causing the climate change. He uses many historical references in support of his claim. John Tyndall, a 19th century physicist, said that humans have a major effect on climate. He also says that gases such as water vapor, carbon dioxide, nitrous oxide, and others have increased the surface temperatures as well. Svante Arrhenius, a 19th century scientist, claimed that carbon dioxide will increase the earth’s temperature. Doubling the percent of carbon dioxide would increase the temperature by four degrees and increasing it by fourfold would make the earth’s temperature rise by eight degrees.
