COMMON MISCONCEPTIONS ABOUT GLOBAL WARMING

Friends of Science: "Myth 4: CO2 is the most common greenhouse gas.

Fact: Water vapour or clouds, which makes up on average about 3 % of the atmosphere, is the major greenhouse gas. CO2 makes up only about 3% of the greenhouse gases, or about 0.03% of the atmosphere. Moreover, because of its molecular weight and absorptive capacity, water vapour is 3000 times more effective than CO2 as a greenhouse gas. Those attributing climate change to CO2 rarely mention this important fact.":
