Kluger and Lindzen's essays are opposite in claim. They claim that global warming causes different things. While Kluger claims that global warming is melting the ice caps and causing the sea levels to rise among other problems. Lindzen claims that global warming is causing the lack of tropical storms. A key difference in each argument was the effect of carbon dioxide levels in the enviornment. Lindzen claims that CO2 will contribute to future warming, but does not make global warming the fault of humans. Kluger claims that CO2 will prove very dangerous to our future, and cites data, such as the fact that during the last ice age, CO2 levels were 180ppm, then in they rose to a comfortable 280ppm, but are now a dangerous 381ppm. This traps the heat in, and heats up our atmosphere. Kluger's argument is much more convincing because of the fact that he cites many more statistics and facts, such as the previously mentioned statistic.
