Many people are worried about carbon dioxide in the atmosphere trapping in heat with a greenhouse effect.

Others are even more worried about methane, which is a much more potent greenhouse gas.

But nobody is worried about the REAL danger... FAR worse than those two is a SUPER POTENT greenhouse gas that is so prevalent and so thick that you can SEE IT making white billowing structures in the sky.

Dihydrogen monoxide!  It will kill us all!
