A. According to the CDIAC [The Carbon Dioxide Information Analysis Center] a primary climate-change data and information analysis center of the U.S. Department of Energy. Greenhouse gas changes correlate closely with temperature changes, suggesting that greenhouse gases have an important role in global temperature changes.

B. A 2001 study done by the CDIAC, found that of the causes of the greenhouse effect water vapor and water vapor alone was the largest contributor, contributing to 65% of the gas emitted.
