- Con to the question "Is Human Activity Primarily Responsible for Global Climate Change?"
“There is little doubt the air’s CO2 concentration has risen significantly since the inception of the Industrial Revolution; and there are few who do not attribute the CO2 increase to the increase in humanity’s use of fossil fuels. There is also little doubt the earth has warmed slightly over the same period; but there is no compelling reason to believe that the rise in temperature was caused by the rise in CO2…
Proponents of the notion that increases in the air’s CO2 content lead to global warming point to the past century’s weak correlation between atmospheric CO2 concentration and global air temperature as proof of their contention. However, they typically gloss over the fact that correlation does not imply causation, and that a hundred years is not enough time to establish the validity of such a relationship when it comes to earth’s temperature history…
In thus considering the seven greatest temperature transitions of the past half-million years – three glacial terminations and four glacial inceptions – we note that increases and decreases in atmospheric CO2 concentration not only did not precede the changes in air temperature, they followed them, and by hundreds to thousands of years…
Hence, the climate history of the past half-million years provides absolutely no evidence to suggest that the ongoing rise in the air’s CO2 concentration will lead to significant global warming…
Proponents of the CO2-induced global warming hypothesis often predict that extreme weather events such as droughts, floods, and hurricanes will become more numerous and/or extreme in a warmer world; however, there is no evidence to support this claim. In fact, many studies have revealed that the numbers and intensities of extreme weather events have remained relatively constant over the last century.”

“The Center for the Study of Carbon Dioxide and Global Change was created to disseminate factual reports and sound commentary on new developments in the world-wide scientific quest to determine the climatic and biological consequences of the ongoing rise in the air’s CO2 content. It meets this objective through weekly online publication of its CO2 Science magazine, which contains editorials on topics of current concern and mini-reviews of recently published peer-reviewed scientific journal articles, books, and other educational materials. In this endeavor, the Center attempts to separate reality from rhetoric in the emotionally-charged debate that swirls around the subject of carbon dioxide and global change.”
