Yep, it seems to be the most valid explanation at this point.The cause of the most recent warming trend may not even have anything to do with any greenhouse gas. It could just be a fluctuation in solar output.
Ha! That sparked another thing that I was going to say, thxP.S. Water vapor and methane are far more potent greenhouse gases than CO2.
Methane caused by large livestock factories (cow slaughterhouses, milk pastures, that sort of thing) is worse than our cars could ever be! All of the massive fart clouds that they make (i'm absolutely serious lol) has a strong greenhouse effect, besides the bad smell of course. All Americans becoming Vegetarians would reduce greenhouse emissions more than All Americans riding bicycles everywhere. Not that it makes much of a difference because the Sun is the one deciding how hot our planet is
