A new exercise in infographics: CO2 facts and short-term forecasts. "(...) while carbon dioxide contributes less to the overall greenhouse effect than water vapor, scientists have found that carbon d... ioxide is the gas that sets the temperature. Carbon dioxide controls the amount of water vapor in the atmosphere and thus the size of the greenhouse effect. Rising carbon dioxide concentrations are already causing the planet to heat up. At the same time that greenhouse gases have been increasing, average global temperatures have risen 0.8 degrees Celsius (1.4 degrees Fahrenheit) since 1880."
