In the interst of making sure the lurkers know that we've got our facts straight, I will point out that Earth's atmosphere is composed of 78% nitrogen, 21% oxygen, and 1% other (0.9% argon, 0.037% carbon dioxide), though at lower the lower altitudes water vapor can make up as much as 5% of total volume. The atmosphere as a whole reflects ultra violet radiation, with CO2 playing only a minor role in that process.
That’s incorrect. Based on the NASA report, CO2 plays a much more important part in preventing the Sun from raising temperatures on Earth than previously known The other question is given the greater percentage and effectiveness of water as a so-called greenhouse gas, why have the scammers focused on a relatively insignificant gas, CO2. The answer to that is obvious. CO2 was looked upon as the next best thing for diverting money from the private sector to government. Fortunately the research continued and CO2 has been proven not to be the fearsome planet changing boogey man as was widely promoted.
