Poll: tomorrow is eath day. Does anyone know what the earth's #1 greenhouse gas is?

water vapor

There are articles by people who may have an agenda other than the absolute truth. Science marches forwards and we figure out stuff that we did not know earlier. There are multiple factors. Did you know that NASA found that the Ice Caps on Mars are melting? Mankind could not possibly have caused that, right? The Sun has got to be going through some kind of cycle. When we look at weather history, with evidence found in the ground, tree rings, major historical events, it becomes pretty obvious that the planet has had several cycles of global warming and global cooling, long before human technology was playing much of a role. I do not believe that any one thing is responsible. It is a combination. That makes it difficult to analyse which is "more" or "less" responsible.

Carbon Dioxide. Carbon Monoxide.

That gas that is lingering in the breezeways of all Taco Bells
