If you figured it out, you should have said something.
CO2 is greenhouse gas. 50 grams of CO2 doesn't float, it sinks. The PSA is trying to say otherwise which is a lie.
There is some CO2 in the atmosphere, but it's always been there. The CO2 that we produce doesn't rise. It's not a pollutant because it can be converted naturally into something usable. It can mix with oxygen and nitrogen, but that doesn't change it's density unless it becomes a totally different gas.
My point of this post is that global warming is bad science. Don't be scammed.
