Default trivia

Out of all the atmospheric gases, what is the most abundant "green house gas"? I will give you a hint, #1 is nitrgen @ 78.08% and #2 is oxigen @ 20.95%, what is the next gas and it is the reason the earth retains heat and it makes up the vast majority of the remaining, .07%

(the percentage do vary depending on where you are in the globe)
