Greenhouse gases and their effects are well-known. Here are some of things we know:
• The most effective greenhouse gas is water vapor, comprising approximately 95 percent of the total greenhouse effect.
• Carbon dioxide concentration has been continually rising for nearly 100 years. It continues to rise, but carbon dioxide concentrations at present are near the lowest in geologic history.
• Temperature change correlation with carbon dioxide levels is not statistically significant.
