That's just false. You might try to rule it out yourself to see. My comments here and the responses demonstrate that it's a waste of time to argue against people in the purity cycle of global warming. My position is one of moderation not denial - and I'm downvoted, told I don't care, and I haven't done even the minimum of research. Pffft. HN is not what it used to be.

You are being down-voted not because of some imaginary "purity cycle", but because you discard without reasoning a vast amount of evidence to the contrary of your hypothesis.

You've heard of the saying that extraordinary claims require extraordinary evidence? Holding a hypothesis of water-vapor from air travel being the primary driver of warming trends is extraordinary.

Invoking the oft-repeated "do your own research" rhetorical crutch and referring to scientific consensus as "hype" doesn't help your case.

It took me about five seconds to find this: https://climate.mit.edu/ask-mit/why-do-we-blame-climate-chan...

Do you have any reason to believe otherwise besides a couple of anecdotes about looking at the sky and short-term temperature variations?
